Exporting 3D .DAE with uv mapping to import into sketchup, excluding certain building features.

[JessicaS]

Anybody have any luck exporting a .STL or .DAE and the materials stay in place with importing into Sketchup using Sketchups native import tool. and how to export just the walls and landscape without framing and every other detail. even unchecked in 3d view full camera or overview it still exports with everything.
