Perfect timing! I wrote a script a couple days ago to derive the “origin” point of .ITM fabrication parts using the bounding box method with OOTB nodes. The code and formulas you showed will make this much cleaner. Thanks!
OMD is this what I think it is?! I've been waiting for this for a long time! :D We had a request to provide a schedule of coordinates to all the BWIC holes in our model by the contractor. There were some paid add-on subscripions that can do this but being able to do it via dynamo just feels so much better! This will defo go to one of my dynamo learning playlist! Thank you so much for sharing this to us Gavin! Will defo start applying this in our models later!
This makes complete sense and I've started to tweak it for another workflow - assign room name & numbers to the areas placed in the same location. But not sure ho to complete the "matchy-matchy" to make the names & numbers apply to areas? I'd send a screenshot f where I am - but apparently cannot do that in "comments"
Fairly different workflow to this. I'd suggest focusing on a level at a time, collect all areas and rooms at given level. Get the centre of each area, and use the room.atpoint node to ask it which room is at the point of the area (rhythm node has this I think). From there its a get/set parameter to transfer the found room data to the area. If you get stuck be sure to make a thread on the forums.
Hey Gavin! I would like to give you an idea for a Dynamo script that people may find useful. Selecting all elements, or selecting with window from linked files. I had a need to do so, because I wanted to merge two models. The idea was to copy from site view and paste, but the models had different reference regarding the internal origin.. So, one option was linking the one model to the other, selecting elements one by one and then copying and pasting. It was really frustrating..
Great video, thanks! Let's say that I want to move the elements to as-built coordinates based on the figures received from the surveyors. What can I do to improve the script to allow me to move the elements by editing the coordinates in the table or family parameters?
It will depend on if the elements are point based. You could use similar conversions to get the point/s though (e.g. a beam is guided by two points), then use element.setlocation to update the related element locations. Hopefully they have element Ids or marks you can use in the data source to get the actual revit element.
@@AussieBIMGuru I was trying to do with Manholes but I have created the manhole family as generic model family. I guess they are not point based. Any idea of how can I do in this case? I manage to get the coordinates but I can't move the elements by just editing the coordinates.
@engjohnattan if a generic model it should be point and level based. Element.setlocation should ideally work, if not a transaction start > move element > transaction end should work. Move it to the point itself, revit families dont understand coordinate values.
Hello Gavin. I´m strugling making this custom node. I´ve managed to make an autolisp from AUTOCAD that extracts all blocks x y z coordinates and list them all to an excel/csv. So from that I extract the points from the csv in dynamo and now I want to make a floor from that csv point files. Any recomendations, it´s very simple funcionality but I´m stuck on the process
Typically you will need the points to be in order of connection as polylines at the bare minimum if the floor does not exist yet. If so you can connect them into closed loop(s) to create a floor, then use their Z height to create points. If your floor has no edge you could look into convex hulls as a way to find the outermost boundary.
Hi Gavin ! Thanks for your great work. I can't find the Real world coordinates nodes under Geometry in the genius loci package. Can you tell me wish version of the package you're using in the video please ?
Not really. Some nodes try to act like they can such as loopwhile but they lack the sophistication like python or c to loop well. If you get to that point I'd say Python is the go.
Hi, it's not related to the video but can you recommend the best PC / workstation specs to be used for smooth modelling and rendering while working on large projects? Thank you and really appreciate your response to this.
All I can recommend is specs as the PC models change too often. 16GB RAM, ideally 32GB 64Bit OS 3.9 or higher Ghz processor RTX3080 Gfx card (Quaddro has been phased out) This will likely cost upwards of $2.5k AUD
I just had a look at revit 2024.1 again and noticed it still has that very washed out interface (main, active text is grey instead of black, which I think you also mentioned a while ago (can't find it anymore now)... is that also one of the reasons why you are still using 2023?...still thinking my $2000 Eizo screen is broken when looking at it....
Mainly the company i work at hasnt made the leap to 2024. Most of our new jobs are 2023 and we may wait for 2025 given the UI overhaul is still half arsed. Some minor API additions like vg link settings but beyond that nothing i feel were missing out on. Toposolids also have some teething challenges and i think users will sometimes miss the old topo tool in some scenarios.
Hi Bim guru, If we move the elements,can the North East values will be updated automatically without run the script again. Is there any way to link the created parameters to built-in spot coordinates tag??
Unfortunately not with dynamo. You would need to look into events and developing addins or pyrevit hooks to trigger and run the update. I believe there are some addins on the market that can do this, but none for free.
Usually best to go back a node and look at the data being fed in, see if there are nulls in there and if there are follow them back to the first node that causes them and that might reveal the issue.
@@AussieBIMGuruHey first of all thanks for your videos ! I have the same issue and for me the input of my node is a regular point "Point (X = - 10, Y = -3, Z = 44)" but still not working :(
@@manghot4413 if the point by coordinate node is giving errors that's odd as it's a very simple node. Check for nulls in your incoming data and if not check your inputs are numbers (not strings).

Genius loci.

Hi there BIM Guru. Is there a way to do loops in Dynamo?
Not really. Some nodes try to act like they can such as loopwhile but they lack the sophistication like python or c to loop well. If you get to that point I'd say Python is the go.

Its in the genius loci custom package.

Could use Dynamo relocate point cloud coordinate base on project base point?
I dont believe so. A point clouds coordinate system is stored internally in the file. You may be able to adjust it in autodesk recap however.
We can do the inverse situation? Convert shared coordinates in a point?
Yes Genius Loci also has point conversion nodes for Project/Survey coordinates to Internal.
How to get four coordinates of rectangular structure?
Same method as this but first get its curves/edges and those four points fed into the same node i use here.
