I had set up a perspective section viewport in a sheet layer. It rendered fine in every rendering mode except renderworks. With renderworks all I got was the sectioned polylines: everything else disappeared. I don't think the problem is with my lights/textures or rendering options because I can produce renderings with renderworks cameras just fine.
So, I tried another method. I followed the instructions on this PDF: http://download2.nemetschek.net/www_misc/2011/GSG/GS-VWA_OffsetDLSVP.pdf
Basically this puts my perspective section viewport in a design layer. From there, I set a 3d perspective view, and I can render fine. Problem now is with exporting. When I export to PDF, vectorworks renders again (uff...). I wait till the already perfectly rendered view renders again, and end up with a blank PDF...
I wish I could understand what is wrong with the first method, which seemed to be so straightforward. Can somebody please help me understand what I am doing wrong?
