@realdrogo this is what I have found to do as well. I have created drawings from a copy of a specific body or assembly that has then been positioned off to the side in line with the X axis.
But you’re correct, the drawings don’t like having their parent body changed. You can make the smallest change and it’s a roll of the dice how the drawing will react.
Hopefully at some point we can select a surface or plane that determines a drawings base view regardless of it’s orientation in the 3D space.
@ricko3k aside from aligning the bodies square, the two dimensions you annotated could be displayed as absolute instead of horizontal/vertical.
