In the past when I Imported X_T or STEP they were divorced from the saved imported .SLDPRT file. The SLDPRT file was NOT linked after import to the original X_T or STEP file. I just had some imported surfaces in the .SLDPRT file ( A true DUMB solid)
But now it is not like that There seems to be a reference in the feature tree to the Original X_T file.
How do I get them totally divorced?
