Curved Openings

How can I get curved sliding doors to show in 3D which are set in a curved wall?

I assume you are talking about something very custom where a curved panel slides past a curved fixed panel along the curve of the wall. You are going to have to model them in parts in SP and assemble as a symbol or create in SketchUp or another program and bring it into SP as a symbol. In SP you can model 3D polygons with different material assignments and offsets to create the parts of a curved door. Or, in another program you can effectively do the same with a little more ease. It's all about creating the pieces that are curved and making a symbol out of them. Then, use whatever arch opening or door you want to represent the jamb and trim, place your new curved door symbol in the correct place and assign whatever textures (assuming you set it up to receive various textures).

In much the same way we did cornerless patio doors in this thread ... https://softplan.com...s-sliding-doors
