Updating line work changes viewport scale

[peter_goodwin]

when I am in a viewport and after I edit survey points properties I am prompted to update linework. if i click yes it updates the linework but alters the viewport scale, even though it is locked. is there a way to prevent this from happening? I know i can switch to model space first but i use the viewports to reduce clutter

If your modelspace cannoscale is not set the same as the viewport scale I would try setting modelspace to match paperspace scale.

the issue is that though the viewport remains locked it is set to a new scale, the annotation scale remains the same.

As a general rule I never update survey data through a viewport. I've seen what your describing, and my only advice on it is to update in model space. Due to the edits to figures and points it's always passing data to the SDB which requires you to be in model space.
