  Hi Support See image below and attached part. When the bolt is put into a 2D drawing you can see that it isn't rendering correctly? Any ideas why or how to fix?

  Graphics issues where drawing views displayed as hidden line and hidden line removed show up with missing edges are almost always due to geometry errors.
  
  I believe this issue might have been caused by the corner of the thread profile being exactly at the bottom edge of the bolt cylinder. I used Fill to remove the existing threads and recreated them. Once that was done the drawing views looked fine.

  Hi Brian
  
  Thanks for the reply but I can't seem to get this to work as you describe.
  
  I think there may be a rendering issue here as it seems to be a bit hit and miss whether you see the correct lines or not.
  
  Created a little video showing this -

  Also tried simply creating a triangle in a new design and revolving this round an axis and getting similar results and I wouldn't expect there to be any geometry issues here.
  
  I'm not sure if this is just a coincidence but when I choose a height value of between 47 - 59 this is when I'm seeing most issues. Above or below that it seems to be more stable.

Sorry for the delay on this one. I realized I wasn't entirely clear in my original explanation. I used copy/paste on the flat triangular face that is used for the thread profile. Then I used Fill to remove the threads. I moved the profile face down just a bit so the corner wasn't exactly on the bottom face of the bolt and then recreated the threads using Pull > Revolve > Revolve Helix.
