[Class Dropdown in Object Info]

On several occasions spanning several MC/Vectorworks releases I have had the dropdown for classes in Object Info stop responding. This same drawing behaves normally when loaded into a different machine. Other drawings on the original machine behave as they should. I have had to delete the drawing and load a backup to continue. This has happened in different drawings. I have not exceeded the max # of classes. ??

[Polygons & changing vertices]

I have experienced this problem in several previous versions. I am currently using Architect and it still happens. I haven't found a cause or solution. Any ideas out there?

[Tubing in 3D]

You may have to use a third party add-on such as MCnurbs or 3D Manager. Go to add on products page and check them out. Unfortunately they are not free.

[Technical Support for Renderworks]

I've had good results from their support. They patiently helped my try to resolve a rendering problem and continued to try to find a solution after I was ready to give up. Did you try to contact them by email or fax? I assume it didn't work after a second try at installation.
