Render Bitmap tool. Adding area lights and line lights makes rendering very slow. I made a texture on the ceiling with a blur, which makes the rendering take longer as well. This has the effect of locking up your computer for 10 or 20 minutes at a time. This is not a great use of your time and it make it hard to make decisions about your rendering.
You need to bring all these parts together, the rendering, lighting, textures and modeling. They all need to work together to make the view come alive. As you add textures, lights, background and models to the scene, Vectorworks starts taking longer to render the view. The answer is to render small areas of your view with the Render Bitmap Tool.
