Navisworks Clashes to Revit using Dynamo!
ฝัง
- เผยแพร่เมื่อ 19 พ.ย. 2019
- This video shows how you can use Dynamo to mark 3D clash locations in your Revit models. This could prove to be a simpler and cheaper alternative for some as opposed to using Navisworks Manage or paid plugins.
I hope you enjoy the session and learn something new! Feel free to comment any feedback/questions below, or follow my channel if you enjoyed this.

It seems the little adaptive sphere is the star of the show!
You can find it, and some other families from my videos here:
github.com/aussieBIMguru/Revit-Files/tree/master/Families
Excellent tutorial - Thank you. What is the benefit of using an Adaptive Family for the Sphere over a normal family containing a Sphere?
@@paulwoodward81 thanks! The benefit here is an adaptive family can be placed at a specific point in 3d space with no bearing on level or offset, unlike a typical level/workplane based family.
Thank you Gavin! These tutorials are awesome. Look forward to the series of Naviswork.
Thanks Nguyen! Glad you liked them :)
Oh my God, I have looking for this tutorial for so long, you made my day. Thanks!!
You're welcome!
Thanks Gavin! awesome workflow / solution as always
Cheers Jose! Appreciate the discussion and exchange of ideas behind all of this
Hi Gavin,
You spoil us with your Revit tutorials and in doing so I have been accustomed to them.
Although there are Navis tutorials out there - I'd love to see how you handle Navis & the workflow you use in your work environment.
Please more Navis videos in your future trajectory.
Cheers mate
Thanks Anwar, once I've been through Python I aim to target Navisworks next!
I'm expecting I'll be through Python within about a month or so, then will try to find some room in my schedule to do this :)
I love love for you to cover navisworks! after this i will be searching to see if you did :)
I think this is the only other video I've done on Navisworks so far;
th-cam.com/video/uwm1N-THKx0/w-d-xo.html
I'll likely make a course on it eventually as it works better in that format I'd say for a program like Navisworks.
Gav,
I'm new to your channel and so far all your tutorials that I've viewed are super helpful. especially because I'm fairly new to the Dynamo space.
thank you so much
Welcome to the channel, and to Dynamo!
I appreciate your take into the programs and connecting them. It would be great if you would also teach Navisworks. Love what u do!
Unfortunately I dont use it much these days, more often than not we use Revizto or BIM360. If I get back into it in future I'll think about it though.
Simply amazing, Gavin!
Cheers mate, good to hear from you!
Very generous sharing of knowledge.
Navisworks tutorial would be awesome!
Thanks Tim! Look forward to sharing my knowledge on Navisworks
Thank you so much Aussie BIM Guru, that was great!
You're welcome!
Wonderful ! (as usual) Thanks for sharing !
You're welcome!
great job, we are looking forward to starting using APIs between Revit and naviswork :)
Nice, that sounds pretty neat!
pivotal dude, awesome content
Cheers!
Amazing Gavin, thanks for all the knowledge..... you have many ninja tricks, again thanks Mr Guru -Rock 'n' Roll-
Thanks Daniel! Always pays to have a bag of ninja tricks when dealing with BIM :)
Really good! thanks a lot for sharing this incredible video.
You're welcome, and thanks!
Great Video! thanks
You're welcome!
Awesome explanation. More intreseted to watch Dynamo videos.
Thanks Nantha, you came to the right channel then - lots of videos :)
This is so great, thank you a lot!
You're welcome!
Thank you very much, it's really great job
You're welcome!
THANK YOU !!
You're welcome!
its really great job, i suggest generating the views with clash name , grid location will be the additional muscle to the tool. This gives the picture , We were underestimating the dynamo , adopting python , since these are possible in dynamo.
Yes Dynamo is capable of many things, even without much python required (a few of the nodes here use python behind the scenes.
Clash to views would be a good next step to this workflow, although it can be risky if users make 1 view per clash - can create 100's of views!
Hey! Love your work just needed to know which Loci version to use this?
Unfortunately it's been a long time since I made this video so I'm not quite sure, but it would be one that has a date stamp around the time I made this video probably. You'll find some help in the comments about how to deal with the updated coordinates node that tends to cause issues given it has changed a bit
Great Video, i have learnt so much from it. However, I am not sure how to build that family. Do you mind to share how to build the adaptive sphere family. Thank you very much.
Thanks Yinglong, I've made a short video here; th-cam.com/video/rGypOZn38Zs/w-d-xo.html
The sphere itself is on my github.
Thanks for all the videos!!! Challenge for you, can you do this exercise
in Grasshopper?
It would technically be possible, but I'm not sure it would be necessary in this case unless your rhino model is the coordination model source as well.
@@AussieBIMGuru Thanks for getting back to me. I'm using Rhino Inside to have all the grasshopper apps inside Revit. this the reason. Find some difficulty with Dynamo. Anyways, love your work.
@@antonwelgemoed6094 in that case I'll try to think of a workflow a bit like this. I encourage you to persevere with both platforms, but I understand new platforms take a while to learn as well :)
@@AussieBIMGuru Great stuff. Thanks
Please share some of Navisworks!!!
Onto the list it goes! Most likely around feb/march i'll begin a series :)
Thanks fot the request!
Further, after adopting the method, I realized that there will be 3 additional blue points created throughout the process, even we when attach the clash sphere, those three points would not have anything to be attached on. When i zoom out of the model. The three points are very far away from each other. This increase the difficulty in turning the model around also when using zoom to fit as they will zoom out to a very far place. Any idea why these three points were created and any resolution to it?
I suspect these points are from the genius loci coordinates node, try disabling its preview. Theyre probably the three base points.
Hi Gavin, I have question for you. I've succesfully bild this script following your tutorial (thanks!) although I had to do a few adjustments, probably because of nodes versions.
Now I'm trying to implement this workflow within the team but there is one more step missing in order to work that I'm not able to finish: here I go>
I've added a new shared parameter called "Clash_Priority" in order to allow the project leader classify them and assign other team members to work on those one. But the problem comes when I run the "second week Navis test" that overrides all the manual input. Is there an easy way to save that data? Perhaps creating another script that overrites first the Navis Excel by adding a new column called "Priority" before pushing the bubbles (this is what I've been trying so far)?
Thank you!
Welcome back to Dynamo land!
I'd modify the script to identify pre-existing clash markers (by checking their clash ID number), and instead of recreating them I would set the existing markers parameter values and use 'set location' node to update their location - this way your priority field isn't lost. Adaptive one point families can simply be updated in location using a single point. You'd need to use some boolean masks to split up the new and existing markers so that you can still create the new ones the standard way.
Hope that helps mate, and nice work on innovating on the script.
Thank you for another great video, Gavin. I was trying to replicate it but the GeniusLoci package node no longer has the Project Internal Point. How should I get it?
There should still be the node in the package but I believe it may have changed in list structure for some of the outputs (e.g. in one the pbp is a point, the other it is a list of values).
You could try using my package (Crumple) alternatively which has nodes to get the various base points, but it would be a bit different to using genius loci in the script layout at that point if so.
Hi Gavin,
I am having issues with the Genius Loci - Get Project Locations node. It looks like they updated the package. I am new to Dynamo and I can't seem to get pass this issue. I was wondering if you could give me some pointers on how to solve the issue. Your video shows (20:00) the node as Active Project Location and the new node replace the Active Project Location with Internal Origin.
Yes unfortunately they updated this node shortly after I made this tutorial. It's really just a matter of reviewing what the node returns now and trying to reach the same values as what I retrieve here, shouldn't be too hard. From what I can see the project rotation is at a lower index in the pbp list output now, and the internal origin is a point instead - so you can deconstruct it to get its X/Y value now instead.
Thanks alot for the tutorial! Hitherto, The method you show is the best way. I followed your instructions, but it doesn't work perfectly.
Maybe my excel file is not compatible. I am new to Dynamo so Can you guide me how to export the Excel file?
In this case I am actually opening the html clash report generated by Dynamo. This can be done in Excel in the open dialogue by enabling ''.all files" and opening the report file, then saving it as an Excel workbook in the save as options.
Thank you very much for that tutorial !!
I'm using Revit 2020. What can I do if I have following warning over the Code Block: There is no version of Get.ValueAtIndex that accepts argument type(s) (Autodesk.DesignScript.Geometry.Point, int). ??
It is the block for moving Dynamo coordinate system, where is written: N_s_disp = int_or[1]*-1; E_w_disp = int_or[0]*-1;
The item must be a point instead of a list - look at the node outputs.
The package manager changed his node after I made this (annoying!) So it now outputs a point instead of a list of numbers.
Grab a look at the recent comments and you'll see the fix ;)
Hi Gavin many thanks for your guidance. really appreciated. I am trying to give some good use of your script but it seems that the Get Project Locations node has slighlted changed by introducing "Internal" Origin" instead of the "Active Project location", but it doesn't work as I get a warning at the followin node "Point.by.Cartesian.Coordinates". Any clue? Thank you!
yes unfortunately the node changed since this video, but you should be able to get the same values out of the outputs using slightly different techniques. In principle you just need to get the NS/EW/Rotation values I think, which the node contains.
I made a more up to date version of the script here also if it helps:

hi please tell us about how to set rule in navis while clash detection to set or group ignorable clash & also moderate clashes in whole with all descplines pls
Honestly I typically set up search sets manually, as they will depend on the data quality you can filter by. I then clash these and use the 'exclude' mode to isolate groups of clashes by common elements. Some addins out there help a bit but I find doing it manually helps me review it all as I go.
Hi Gavin! Thank you very much for this tutorial! I just have a question. In my case this works great when the survey point is at (0,0,0) but it's failing me when the survey point has different coordinates. Do you know how could I handle this situation? Thank so much!
In that case you will likely need to compensate the offset applied by the survey point's difference. The model typically relies on the relationship between the internal origin and the project base point the project base point's values could be used for the offset as well given it's relative to the surveyed coordinate system.
@@AussieBIMGuruThank you very much for your reply! On the meantime I found that the Genius Luci package has a node that allows you to transform survey coordinates to internal coordinates. It doesn't place the element at the exact point but it's close. I'll give your solution a try! Thanks again for the amazing content.
Hi I'm new to Naviswork and Revit. Would you please recommend how to set up Revit to easy transfer and search in Navis. Thanks
Hi Huynh, to export to Navisworks from Revit, go to R > Export > NWC.
There are some settings you can adjust here to optomize your export, typically if you search for the properties tab and export all your data this works best for review purposes. You will need fairly clean data structures to take advantage of elements in Navisworks, so I suggest using shared parameters in Revit if you aren't already.
Hi sir
Thank you for this video.i did same thing in this video but when i come to ' coordinate system rotate ' i am having issue.Issue is my clash ball dont stay in my project.Also my project has elevation value and i dont set code.block bottom of coordinate system rotate. How can i fix that ?
To correct elevation discrepancy, you would need to add the elevation of your internal origin to your points, probably using the translate node at the end. Usually people keep this point at RL 0, but it looks like you must have it higher than this.
If the translated coordinates aren't working, there is probably an error. Check the rotate/move steps are working a few steps at a time carefully.
Hi Gavin.
My task is either doing MEP coordination or cost control depending on what's available for me.
I am zero in Revit, Navisworks and Dynamo.
My question
1. which one that I should buy and learn 1st and thereafter.
2. do u tailored course for individual like me.
Thanks in advance.
If you are measuring a Revit model then you should focus on Revit itself. Coordination is probably more widely needed in the industry versus cost control, unless you are a quantity surveyor. I have a video coming out next Monday on using Dynamo for cost takeoff, and my video from Monday of this week focused on Revit and cost takeoff.
I don't do tailored courses as they would take too much time and not be affordable unfortunately. Most of what I do here for TH-cam is my spare time, whilst otherwise I do paid consulting services. My rates are targeted at western markets also (as I live in a country where everything costs equivalently), so are usually not affordable in other economies or for individuals.
Very interested in this workflow. Can you tell Revit to automatically adjust the clash and what happens if you are using fabrication parts with rolled 90s and 45s?
This workflow is mainly focused on marking the clashes so users can judge the solution within their model.
Technically an alternate script could be used to reroute ducts through clear space adjacent, however each scenario would be rather unique so it would be a very lofty challenge (far more complex than this script). It would likely involve generating a 3d space lattice using Topologic, removing all points within duct size tolerance of neighboring pieces and finding the shortest possible route through the remaining viable points. MEPover could then turn this geometry into ducts and connections.
Aussie BIM Guru would you be open to creating this for us? Do you work for hire?
@@slidewalker whilst I will be running my own BIM consulting business in March, my insurance doesn't cover me for work in the US (good old patriot act!). Looks like you're in Birmingham AL? Hoping to expand it once it grows in a few years.
I would get in touch with Sigma AEC Solutions and Sean Fruin - he is a strong Dynamo MEP consultant (I'm not as experienced with MEP) who does script building (one of the best I know) and is also state side. I believe this idea would be of interest to him. Would love to hear how it goes if you do
Thank You Aussie BIM Guru for the detailed tutorial, nice work! However, I came across the issue of not being able to use the get project location from the Genius Loci Package that you used. How can I resolve this issue ?
The node has been changed since my tutorial unfortunately, but the data can still be obtained, it's just in a different structure. I will likely remake this tutorial eventually with a simpler method that doesnt use the genius loci node - it has caused a lot of trouble and time for me due to being changed after i made this unfortunately.
@@AussieBIMGuru I faced the same problem, I am blocked on getting the active project location and would love to see how it can be resolved. Thanks again!
@@joannahalal8614 it needs a different approach. Use point.x and point.y on the points to get the N/S E/W values instead.
@@AussieBIMGuru it worked :D :D !!! thank you so much !!
Hi Gavin assistance would be appreciated. I have worked through recreating this script however I have come up against an issue when I run the script the Point.ByCoordinates has a warning and doesn't work I believe from reading the geometry scaling needed changing which I have set to Extra Large however the points are still outside dynamo range.
Yes this can happen, it may be worth using Genius Loci and its coordinate translation nodes instead as that does it without the need for geometry to be processed distantly in Dynamo's preview.
Can yuh please share the demonstration video for sphere..
Sphere family here:
github.com/aussieBIMguru/Revit-Files/tree/master/Families
Hi , Aussie . Greatful idea for using our work. I want using your idea. but i can found you using node(ex. get project location) . how can i search that node and download ?
This node has changed since this video unfortunately. Feel free to email me and I can send you an updated version.
Should we learn navisworks or revit for building coordination process?
I would learn both, as well as ACC/BIM360 platform. All our necessary. If you are a team leader or coordinator a platform like Navisworks may be worth investing more time into vs an authoring side such as Revit though.
Hii... Great video... A small query.. When I imported some points from autocad they are placed at a far position and I unable to correct those because I have my north/south and east/west values as 0 in my model so I am unable to measure the
distance and there is no vector to pull the points back at original position.. How should I do that..? Kindly suggest me Gavin.. Thanks in advance..
In this case you may need to manually measure the differences and build the vector from XYZ components in Dynamo instead. I would try the genius loci package which has a node for reading blocks, or bimorph nodes with one for lines on layers instead maybe unless you're using the dataextract tool in AutoCAD.
Hey Gav, i exportet a Revit Projekt to Navisworks to do the clash detection. Now i want to prozess your updated scipt but due to 0 roation i get an error in the group "Translate points, make adaptives", do you have any recommandation to work around this? Bescause i would like to have ur scipt in case of a rotation but also the oppertunity to work with the script if there is no rotation or different project base point. many thanks in advance and best regards :)
Try using the internal to project coordinates node from genius loci package as an altefnative for converting the coordinates.
Hi Gavin Nice Script..In dynamo we can get spot coordinates from element location points but is it possible to get location points from spot coordinates..? Thanks in advance
Not that I am aware of - can't see any API for this.
Good work gavin...I have elevation difference in survey and project base points... how do i proceed that..
Subtract the two elevation values and add or remove from the z values of the points; whatever combination gives you the adjustment you need.
Alternatively you can translate (move) the points instead by this value.
@@AussieBIMGuru Hi Gavin, firstly thanks for the video, I really admire your work, it is helping me a lot.
I did the same script following your video, it works fine just the point come in a different elevation because the model has an elevation difference between Base Point and survey point.
Active Project Location (Z=0)
Base Point (Z=0.3)
Survey Point (Z=0)
I tried what you suggested in this comment, but it still didn't work, but it worked when I subtracted 4700 from all the Z values of the points.
I cant find any relation, why the number is 4700 to the point to fall right in place. Do you have an idea why?
Thanks again.
Hi from august 2021 and thank you for the video! I am sure that I can't criticize free educational content (especially so useful). But I have to say that working with custom nodes with no information about packages versions is really painful. Genius Loci, for example, "Get project locations" node has another output pins functionality in my current installed version. P.S. Sorry if there is version info and I just missed it.
You're welcome. Yeah I mostly use my own package these days where possible as sometimes nodes change and I'm not typically aware of it as the packages I use tend to have 100s of nodes. I typically work with the current builds at time of recording where possible for reference.
My hope is that people can apply their knowledge of dynamo if they come across slight changes in the node functions as even the dynamo nodes change sometimes as well.
One of the issues with youtube is it cant really be updated (just removed). This has in part encouraged me to develop a course platform in future to capture more structured and updatable content.
Hi Gavin,
Assuming one had real world raw GPS data, long, latt and elevation. Would it be possible to have this show in the same manner in the Revit file ?
Cheers Gavin
Probably not due to the 10km window of comfort the software works within. If you could set the revit origin to be within this distance in relation to the numbers it's possible though theoretically.
@@AussieBIMGuru Cheer Gavin. Appreciate the insight
Truly inspirational. Can't thank you enought. I have followed your instructions, and concluded that when you add more information form Navisworks (like Layer Name, Item Path) ID columns are not next to each other, so I made some slight corrections and additions to your original script. Hopefully you dont mind me sharing it on Dynamo forum.

Thanks! More than welcome to share the idea and script (it's on my github anyway).
It's always great to see people innovate on my ideas, I always have to stop short of the 'polish' so it's never quite complete. Nice work on adding those extra touches :)
I'm using vuk vukanic script but get an error on Custom node definition is not loaded.
@@zulamri6447 I listed the required Custom Packages needed for the script to run in the description within Dynamo. What node is showing the error?
Is there any way to filter those clash spheres using dynamo (I'm trying to automate all the process) ?
Yes you could apply graphic overrides using dynamo in the active view, but I would suggest building view filters into your project template is more suitable long term.
What's the best way to get the HTML into Excel?
There is a good guide here; www.myofficetricks.com/how-to-import-data-from-html-into-excel/
Alternatively, you could use python to read the html file using regex pattern detection also.
How add matyrail import solid work components in Revit
I would suggest getting it into a format that can be imported to a family editor such as dwg, 3dm, sat or skp. You will lose most functionality/parametricism however, so usually it's best to use this as a base and remodel as native geometry after - the programs aren't really that compatible.
There's a thread discussing it in depth here;
forums.autodesk.com/t5/revit-structure-forum/converting-solidworks-assembly-to-revit/td-p/6783547
(Warning: Your inputs lie outside of the allowable modeling range, consider choosing the Extra Large setting with a modeling range between 1 and 100,000,000 from the "Settings => Geometry Working Range" dialog)
This is the only warning its shows, i've change my geometry setting to extra large but still its showing the same error and points also not highlighted in revit model. i don't understand why ?
could you help regarding this
Your coordinates must be quite far from the origin in your model coordinates system from Navisworks prior to translation in Dynamo - that's my guess...!
Usually this warning is ignorable, and if extra large units don't correct it there isn't much more that can be done I believe. Might be worth cross checking your project coordinates system vs. the internal origin and making sure you aren't making any points more than 10km from the origin.
@@AussieBIMGuru Thanks Aussie , Could you tell me what packages were installed in your dynamo ?
In this script I use Genius Loci and Bumblebee.
The genius loci packagi i downladed (for rvt 2020 latest) is not the same you got in your videos . The get locations node now export a point instead of list of values. Might need to update it.
Yes it's a different workflow to retrieve the same values now. Hopefully viewers can discern how to obtain the same starting values (it's not too many extra steps). If i remade my videos everytime custom nodes changed I'd be remaking my videls quite often!
Great script. But it places spheres at very far points outside my model. I guess I need to workaround between coordinate systems.
Yes the steps I added in the video should account for discrepancy in coordinates ideally...
what is the code block for z displacement,
the project im working on currently has a Z displacement but in the video you only gave N_s_disp... and E_w_disp... what would be for Z
Z would be the elevation property of the project base point.
it seem that genuisloci is different from the node that you had use for the tutorial is there any work around for this? thank you so much
@@user-xi3tv8dw5p it is different, yes. It changed later unfortunately. Later revit builds have standard nodes for getting these values under revit > coordinates I think.
@@AussieBIMGuru I'll try to look into it, appreciate your fast response and this tutorial is very helpful for someone who's starting out! :)

@@dodiisnandar4287 yes you can generate a clash report for any NWC vs another NWC. The names of the parameters being isolated in the report (in the header row) should be the same regardless of the file.

yes please, i love Navisworks, but......
But....?
To see the clashes back in revit is a crime. Searching on ID’s and so.
And to the timeline working is even worse. Can we do something about that?
I’ve to say. I’m a MEP engineer.
@@BeneBraad Hrm I wouldn't go as far to call it a crime... I agree that an experienced user could work fine with switchback and ID's but on average I notice users find this workflow saves them time. It's important to remember that on average most Revit users don't know how to use Navisworks (which to me is the true crime!). Also worth noting Navisworks Manage is outside the AEC Suite, so not every user has access to the clash detective to review and fix issues - manually pouring over the clash report is a clunky workflow vs. visualising the locations in the software I think.
Obviously they need to clean up as they go, rather than just dump in clashes and leave markers behind, but given the remodelling is undertaken in the model itself and not Navisworks, I see value in this workflow (and have seen it used successfully by teams before).
BIMTrack is a good integrated solution to this problem also, but not every firm will throw money at it unfortunately.
I'm not 100% sure what you mean by timeliner issues - assuming you mean that handling elements by timeline is difficult in Navisworks? In my experience most firms will typically add a parameter to all elements in their model on an instance basis and then populate this with the associated phase of construction, then they animate the search set of this field in Navisworks. It gets messy when you want to divide slab pours etc. and the model hasn't been broken up though - usually I find that communication with the builder is critical as early as possible if this is a project BIM goal.
Ideally it should be captured in the BMP as a specific modelling requirement if LOD does not require it. The builder should ideally have a BIM auditor who can verify the model will achieve the 4D requirements also, otherwise no-one takes responsibility (and it usually just gets dumped on the architect in my experience).
