Hi,
I have been using Vectorworks for many years and i have only come across this problem recently.
I have tried to render a 3d model and my pc takes ages then does not even complete the render with a message stying 'Low memory'.
I have not installed any new software which may affect this. I have tried to render the same file on the VW 2011 trial version but the same problem arises.
I have the same file a while back with no problems on the same pc.
What can i do to resolve this?
