Thanks, this is fantastic, almost the best way to resolve the fences following the topography.
You're welcome! I'll revisit in future to do staged/stepped foundations which are the best reflection of real life, using this as a foundation for the script.
Very useful indeed ! Great script, many thanks !
Youre welcome!
Would love to see a video on how to model construction batters
Hrm to be honest it's very difficult and as an architect I never have to do it (luckily). I believe most civil engineers typically manage batter/cut/fill calculations in separate programs like 12D or ACADC3D. In Revit the only tool we really have is the 'graded region' tool which can compare phased topography and report on the cut/fill areas between them, but it's a very difficult tool to use accurately as a civil engineer.
You are a Genius.
If You have to create multiple walls at once to compute material over de Surface, what am I supposed to change in the script? Sorry, I'm a newbie with Dynamo.
Thanks in advance
This probably isnt the easiest workflow for a beginner, but you could get the polysurface of the topo and try splitting the wall surface with it, then taking the area of the lower split piece.
You are a genius man!!!!!
Thanks, I do my best!
Hey Gavin! Really enjoy the videos- good stuff.
I have a question about using Revit to model bridge structures- when making a bridge model, the span of the bridge usually has to follow a certain road alignment (this aligmnet is done in Civil 3D and from that alignment (or surface) it is possible to get coordinates (X,Y and Z) to than import them into Revit through Dynamo). I then create the span that follows that line ( usually curved in elevation view, but can also be curved in plan view). The problem comes when the road alignment has to be changed and the points and further the line has to be created again and the span has to be created again. Is there a way that it could be done that when the created bridge span is somehow parametricaly connected to this line that is created from those alignment points,so that when this alignment chnages it counld be possible to update the span faster?
Have you ever come across any companies in Australia creating bridge BIM models in Revit? Maybe some other pograms are popular in Australia for bridge modeling?
Yes usually firms use complex adaptive components in order to place and set the bridge viaducts and components. Dynamo is probably the easier part whilst the families take longer and require sector specific expertise.
Check out this presentation here for an example of how this works:

yea, I had a similar error when switching scales while doing something different.
Glad it wasn't just me! So strange.
Awsome!
Thanks!
Hi Gavin! Excellent tutorial as all your other contents. I’m following your steps and it goes well till the end. Wall.ByProfile doesn’t create the wall and give a warning. I’m using Revit 2022 could be this the problem? Something related with the Forge Units thing? Is there any solution?
Now I did the same script in Revit2018 and totally worked
Yes I suspect its a unit type issue - those changes are causing all kinds of issues for custom packages that aren't up to date.
@@AussieBIMGuru Thanks for your answer! I’m waiting your next video
Thank you legend
You're welcome, thanks for the request! I'll revisit this in future to add a stepping foundation approach as well.
while connecting "topography.mesh" geting error "one more geometries have failed to convert due to this error: unable to create Line. Points are likely Coincident"
A common error for complex meshes. Maybe try manually deconstructing the mesh using element.geometry and getting mesh from that list.
Hi Gavin,
This is terrific. I actually need to calculate excavation volumes in Revit. I have 2 Topo surfaces and I need to create a mass by connecting the 2 tins. Is there a way?
Not natively in Revit as far as I know. You might be able to join them as a mesh and make a direct shape from it, but it wouldnt be editable topography.
@@AussieBIMGuru If I create 4 walls around the topo area. TOW follows the top topo surface, and the wall Bottom follows the bottom topo, which will create an enclosed space that will have a volume.
@@muhammadfaraz7052 yes dynamo can make meshes from topography and also make direct shapes. I believe the springnodes package can do both of these things
@@muhammadfaraz7052 yes this could probably work. You would need to intersect a volume around the walls with the topography.
Ignore the above plz. The room will not compute volume, my bad.
a query. because the option "Mesh.topolysurface" does not appear. Thank you, I await your response
It should be in spring nodes package.
@@AussieBIMGuru It doesn't appear to me, is there a way to install it?
The package manager can do this under manage > search for packages.
could you list packages used in the scene?
Watch the intro segment.
i reply your squematic routine but not working.
You can i have this script, please?
You can find most of my scripts on my github, datestamped by video release date.
@@AussieBIMGuru Thanks for sharing your routine, but some errors occured on launch this script. the final node show this error "its not possible project value null for double" and the node curve.startpoint show this error "internal error, info unref one non index" and point.z show this error "internal error, info unref one non index"
Sorry about that message but i need make walls in my final work in my university and i going crazy because i´m not making my walls following my topo, help me, please.
@luisfernandotelesdesousa6677 likely the topographt is too detailed and has caused more complex geometry than my example. Unfortunately detailed dynamo troubleshooting is very difficult via youtube, id suggest making a thread on dynamo forums, sharing your progress and asking for further assistance from the community.
Hi, could you share the Dynamo file pls
All on my github

@@AussieBIMGuru Thank you!
couldn't find mesh.topolysurface
Springnodes should have this.
@@AussieBIMGuru thanks!
@aussieBIMGuru where can I find spring nodes?

Yo if we talking user requests I got a hot one for you. Write rooms sizes to rooms. I know this is possible but sounds like a pain to setup
This is typically how I do it if we're talking cross dimensions: th-cam.com/video/LFIxJC6cwGs/w-d-xo.html
@@AussieBIMGuru Man this is gold thanks! of course now I have another puzzele. i want to create model lines from core face exterior reference lines on walls. Cant seem to figure out how to make a curve from the references. or maybe make a curve from the walls and then move them to the reference? idk. going to use it to trace links when their modeling is shite and I need to clean it all anyway.
Yes i would probably try offsetting location curves, but corner cleanup will always be problematic. Maybe consider taking room finish boundaries and clashing their midpoints if you need to identify the wall they belong to.
how to find select model element (change) has to be copied from select model elment select? lol
Not quite sure what you mean, can you clarify? Select model element is a node which comes with Dynamo by default.
Nice tutorial Guru! But what happens with the length and area parameters outcomes? Can I trust it?
In this case area is correct but length is not. If you wish to get the true length along the surface of the topography you would need to calculate it from Dynamo and then set it to a shared or project parameter on the wall using the script. The length would still be the flat/linear length of the wall.
@@fukuda6025 it is a very generic error. My best guess is the wall may not support the algorithm (e.g. it has openings, or is on a curve) but I'd need to know which node is giving the warning.
@@AussieBIMGuru Thanks Guru! I followed all steps but my wall seams to appear only as analytical form, not as an element, with this ''Warning: Wall.ByProfile expects argument type(s) (Curve[], WallType, Level, double), but was called with (double, Revit.Elements.WallType, Revit.Elements.Level, double).'' I'll try to reinstall my Dynamo
Thanks man! Any alternatives to Wombat on Revit 2024? Wall.ByProfile It's not working. I got this message "Method not found: 'Int32 Revit.Elements.Elment.get_Id()'."
Not that I know of, unfortunately they changed the integer types to both 32/64 bit in 2024 so many custom packages will have errors here.
@@AussieBIMGuru thats what I tought. Thanks! 🤝
