I'm struggling to understand why having set an offset distance for dim lines using the DIMSTYLE and Modify panel. My dimensions are appearing at the correct distance as a preview for body selections then reappearing at a seemingly random though very close distance from the geometry so that I have to drag it out again to a random distance which means that after adding a few dimensions they are all set at different and random distances from my object. Why is this and can it be worked around some how?

all best
