I am an absolute beginner with CAD. I am trying to model a bolt and nut so that I can test it failing under various condidtions. I Have been following this video https://www.youtube.com/watch?v=LyMfcRl71do which is very useful, although I only have a student account. Just as I was about to get to putting the thredad on my bolt, the video at 14.53 tells me to open a file called unf_external_thread_profile. Which I dont have. Can anyone help me with this?
Also I have built the bolt so far need to convert it from inces to mm, is this possible.
Sorry to ask such basic questions, but like I say this is my very first time using CAD.
Cheers
Marcus
