Convert a Flat 2D survey CAD into 3D Topography

[Mark.Ackerley]

I think Jonathan is hinting that you might post a .dwg…

I’d be interested to see the video, I haven’t seen it, but this post suggests you can’t get CAD Text into Dynamo…

Data attribution using information from a CAD file

Unfortunately text elements within a DWG or DGN are not exposed in the Revit API (and therefore Dynamo), which means there is no way to access them. The only option is to explode them using the standard Revit Explode command, then you can filter these elements using Dynamo. I believe there is a way to do this using the RevitAPIUI, which simply automates the explode command (see link), however its limited to Revits 10000 element limit. @jacob.small suggestion is worth pursuing if you are an Au…

That means you need to import and explode the CAD to get the text values.

I’ve had a quick hacky go which might help if you can’t find your video . I’m sure there are mistakes for more complex files but it seems to work and it should have most of the useful nodes for you.

Hope that helps,

Mark
