I have a few templates set up with custom settings and stuff to suit modelling our bottles and producing drawings, there's one for parts, and one for drawing which I use a lot. On the drawing template when I go to sheet properties its set at a scale of 1:1. I have the various different views set up on this template so that when I'm working at a part and click make drawing it opens up this template with the views required set up. The problem is when I do this the sheet scale changes from 1:1 to 1:2.

Why would that be happening or is it something to do with the part?
