Design layer viewports not rendering in Open GL

[jamesmise]

I'm not sure why some of my design layer viewports render in open GL and others don't. They render fine in fast or final renderworks.

This problem seemed to occur when I referenced the same file many times. I'm desiging a living room/kitchen scene. All of my furniture has been drawn in a separate file and brought in as design layer viewports. This keeps all of those furniture classes from cluttering up the organization of my main drawing.

It seems that after I created 6 or 7 viewports from my furniture drawing, the viewports started acting up. Some wouldn't render in open GL.

The solution was to make a 2nd Furniture file so all my viewports are not coming from the same drawing. The chairs, sofa and tables come from one file. The kitchen cabinets, refrigerator etc.. come from another file.

Also, remember anytime things start acting up, first try closing and reopening your file. Or try restarting Vectorworks, or even your computer. This has helped many times.
