in solidworks assembly environment when i m inserting a part, the explorer set to inventor file as default. every time i have to change it to .prt or all files. unable to find any way in option menu. please help if you know how to fix it.
Can you detail how you are adding parts to the assembly?
It likely seems like a dumb question, but I've never had SW think I wanted an Inventor file.
Is Inventor loaded on your computer? Have you tried to insert Inventor files in an assembly?
There are also several ways to add files into an assembly, so knowing the method you use (and the version of solidworks) could help narrow down the issue, or at least let me/us try to duplicate it.
