You could set up graphic overrides, save a 3D view in your View Map with those GO settings applied and publish that to BIMx.
This is a bit crude though, as it will override entire elements. For example, if you override a brick texture surface with a white paint, it will apply the white paint to all sides of a wall that has the brick texture anywhere.
You can also switch to white model in the BIMx app or hidden line, etc. These will simplify the way BIMx shows the model, without needing to change anything on the ArchiCAD side of things.
Thanks that worked (saving a GO view)(always forget about the saved view controlling the BIMx)
I needed to produce a BIMx with NO materials as clients sometimes get overwhelmed with materials in early design stages. Changing the settings in BIMx is not the answer.
