A long long time ago - before the custom property editor was born - I used a macro called "swCP3" to create custom properties...

Now despite many major releases of SW and a few new computers, this macro is still hanging on somehow.

When I run FeatureWorks on some imported parts, i get the error "Following features are not supported by FeatureWorks. swCP3Attribute. FeatureWorks could not proceed further."

I cannot find out where this artifact is coming from, and how to get rid of it!
