Thanks, this is fantastic, almost the best way to resolve the fences following the topography.

Would love to see a video on how to model construction batters
@AussieBIMGuru 3 жыл бұрын
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
@AussieBIMGuru Жыл бұрын
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.

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?
@AussieBIMGuru 3 жыл бұрын
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: kzfaq.info/get/bejne/bMeHfLek3JbVoX0.html

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?

@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.

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.

Nice tutorial Guru! But what happens with the length and area parameters outcomes? Can I trust it?
@AussieBIMGuru 3 жыл бұрын
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.

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.
