Hi 

I have attached a video where I am trying to add smart dimensions to lines in an assembly layout sketch (3D sketch by default). Some of them work as expected, but the majority snap to horizontal or vertical dimensions when I try to place them. As I want to be able to alter line/block lengths to refine mechanism geometry before moving to 3D I need to be able to place these dimensions. I have tried starting in both safe modes, and the problem persists across 2 installs (2020 academic and 2021 academic) and different machines. I contacted some one else who has said they do not have this issue in either 2020 or 21. I have been looking at snap settings but cannot see anything specifically relating to dimensions or 3D layout sketches.

Can anyone help?

Kind regards,

Ross
