Reasons To Be Cheerful Part 16 (upgrading to 2008) Foreground and Background Rendering
Until now, you could only choose one sort of rendering for each viewport. The workaround for this was to create a copy of the first viewport directly on top of the first viewport. This works OK, until you want to change the view on the viewport.
With VectorWorks 2008, you can now set background and foreground rendering modes. This makes it easy to set up the viewport you want, with the rendering you want. If you change the view, the viewport can be easily updated.
My updated and revised Architect Tutorial manual for VectorWorks 2008 shows you this technique, available from http://www.archoncad.com
