Hi: The company that I work for uses the name of the base solid in a part to help identify that component in an assembly. Example: You rename "extrude1" to "BRACKET, MOUNTING, ROTARY SHUTTER" .. Then when move your mouse over the component in the assembly, the popup shows what the part is. This is helpful when working concurrently, and you many not recognize the part numbers.... Anyway, the only way to do this is to copy/paste the text from the Description Custom Prop or to retype it. Has anyone out there written a macro that can simply take the text from the custom prop and write it into the name of the first feature? I don't really know anything about macros but this seemed like an easy one. Any help appreciated. Thanks, Todd
