Convert DWG solid colors to OBJ

V

I'm trying to convert a DWG with solids to an OBJ mesh.

The conversion is good but the OBJ doesn't include the color of the solid ("autocad_color").

 

I tried GeometryColorSetter but I can't seem to set it up properly.

geocolsetterI also tried the AppearanceSetter, following this post: https://community.safe.com/s/question/0D54Q000080he8G/how-to-set-the-color-of-an-ifc-objet-ifcproxy but I can't set it up correctly

 

Could you give me some suggestions on how to setup the transformer GeometryColorSetter (or a better one) so that it takes the "autocad_color" of the geometry and gives the same color to the resulting obj.

Hi @vlabs​ ,

You should be able to set this with the fme_color format attribute since it holds rgb values rather than color index values like the autocad_color format attribute.

Alternatively, you can use an AppearanceExtractor before the AppearanceSetter. The autocad_color format attribute is an AutoCAD index color between 1 and 255. In order to preserve the actual color, you'll first need to extract it then apply the color properties in the AppearanceSetter.

 

Hope that helps.
