When I open an old plan in the current program version, I sometimes see a message stating:
What does this mean?
Materials are represented by patterns in 3D views using a variety of rendering techniques, including Vector View, Technical Illustration, and Hand Drawn Lines. This message will display if a material in the current plan has a problem with its pattern.
In most cases, no action is necessary because, as the message indicates, the program has reset the pattern to resolve the problem.
If you use customized material patterns, though, you may want to locate the material in question and confirm whether the default pattern definition will meet your needs.
