I have been creating custom properties for a few components in our Toolbox. There have been issues of these custom properties not being retained after being inserted into an assembly. It is almost as if SolidWorks removes the custom properties after the part is inserted. Also inserting a part with these custom properties 90% of the time results in Solidworks crashing. I have tried various part configurations form the Toolbox and once I add custom properties the part will always cause Solidworks to crash upon being inserted into an assembly. Any information or tips would be helpful.
