Hi all,
I created a library feature part and when I try to use it as a structural member, it's telling me it's and invalid member profile. I've created it the same way as my other profiles so I don't know what the problem is. I can make a extrude out of the sketch but it doesn't wanna work on weldments?
Welcome to the forum. My first thought was that the profile hadn't been saved correctly, but from your screenshot it looks like it was, so there must be something else going on. Can you post the file here for someone to look at? See How can I attach a file to a forum post? if you aren't familiar with the process (it isn't intuitive).
