I modified a model which I brought in from the 3D Warehouse (I changed a couple of the finishes) and I saved the new model and also exported it as a 3D model. When I tried to import it to Chief Architect (X-11, not all of the new finishes were brought over (oven door should be black instead of stainless and handles should be in brass instead of stainless). I’ve attached both files.
