OBJ to Rhino to Revit with colours

[s.murphy9485]

Hi, I am trying to get .obj into rhino7 to scale it and then export a .obj to revit with colours.

I have an .obj file with an associated .mtl file but no .jpeg file. I can open the .obj file in Revit but it has no colours. When I open .obj file in Rhino7 it has colours. When I export an .obj file from Rhino7 to import into a Revit family. It has no colours. Is there a away for me to export this .obj file so that when I import it into Revit the colours show up?

I have done this before with.obj files that had an associated .jpeg file but that jpeg file is missing this time. I don’t have Rhino.Inside Revit, but I could maybe download MKS Beam if that could help.

Any suggestions would be appreciated?

You’ll have to convert the face color or vertex color to a texture map.

Yep this works thanks

Convert mesh vertex colors to texture map, export OBJ

I made a Python component that takes a Grasshopper mesh with colored vertices, puts texture coordinates on it, and creates a texture image file. I translated this from Vicente Soler’s C# component that I found here. I added the option to export the textured mesh to an OBJ file. NB the texture map that this creates is vile. It’s just a pile of pixels, one for each mesh face corner in no particular order, so no meaningful unwrapping has been done and you can’t use it to paint. All you can do w…
