Convert 3D CAD to Revit Family Geometry

[qixing.chenNYA88]

Hello,

I am new to Dynamo. I want to convert 3D CAD to Revit Family Geometry so that I can apply materials and use parameters to control it. Can anyone share the Dynamo script to achieve it? Or what are the resources I can learn about hoe to solve it?

Thank you for your help in advance.

I don't have the Dynamo script for you, but have you tried using the "explode" button when importing the CAD import into the family? That usually forces the geometry to no longer be a link but to instead be normal family geometry. Although there is a limit when using the explode tool. It doesn't work if there are more than 10k surfaces. U can adjust the surface count in rhino if you need to. The explode tool is also riddled with errors, however, and sometimes refuses to work. 

But might be worth a try if your geometry isn't too complicated.

Yes, I have tried the Explode tool before. It works. I would try Rhino if I
met the problem. Thanks. Have a good day!

I doubt there is one. But you can try to build one yourself.

Dynamobim.org

If you just need to assign materials then no need to explode.  If you need to manipulate the family geometry with parameters then the only path forward is rebuilding the family in Revit, not Rhino, not Inventor, not exploding.

Post the CAD file you want to "convert" to Revit.

Hello,

I just download Rhnio and import CAD. Could you please show me how to adjust the control point count？

The file is on the attachment.

Thank you very much!

Are you saying that you want to "convert" 220 AutoCAD Lines, Arcs and Splines to Revit Lines, Arcs and Splines? Why?  

[qixing.chenNYA88]

No, exactly. I want to convert 3D geometry so that I can use parameter to control visibility and material.

There is no 3D geometry here to "convert". There's only Line, Arcs and Splines. 220 in all.  Besides that, you can easily create Revit model geometry using these lines, arcs and splines as references. If you started now, you could probably have it wrapped up by lunchtime.   A bunch of simple extrusions is all I see here, and Material is just a property of the extrusion.
