rendering problem in Rendering Posted March 7, 2001 Make sure you have at least 96 megs of free ram available prior to your opening VectorWorks. I had a problem where I had Vectorworks and another program (MS PowerPoint) open at the same time and the demo I had wouldn't render. Once I closed PowerPoint the rendering was fine. 14 seconds to render a 1.6 meg size model! My client was impressed!
