I tried the method with Assembly Insert Existing component , but it says "The license is not granted , Transfer aborted" . I tried changing some data in text file in CatiaENV , still doesn't work . I now know that i need Reverse engineering license or something , and i have the student edition which i got for free for one year from Dassault. Is it possible to install the license for Reverse Engineering ? Is there another way to solve this issue ?
