I use sheetmetal every so often but hardly ever use the forming tools (except louvers on the rare occasion). In 09 (even 08) I had no issues, I would go to the design library and select the louver I wanted, drag it to the sheetmetal part, drop, locate, and blamo the louver was there. Now in SW10 sp1.0 things aren't the same. First I had to add the location of the Library (I used the generic sw10 design library folder) then I select the louver and the first thing I'm asked is if I want to make a derived part (which I do not believe I want). I select no it opens the part file for the louver, if I select yes it just adds the part file to the sheetmetal (which is a solid part).... I'm miffed, if I'm doing something wrong I have no idea... This is the first time I've tried to use forming tools in SW10.
