This is getting a little tedious! SU2021 is just not like the previous version insofar as drawing accurately! Push pull does not work properly - pushing a new area sometimes does not erase one or two sides of say a rectangle, dragging a guide does not stick to the red, blue or green axis often, new lines do not tie in with previously set up groups. I used to like it when new lines actually joined previous lines EXACTLY, now its just a hit and miss with line overlapping, lines that represent two blocks or groups don’t line up. Then try to dimension all these inaccurate and double lines is just another nightmare.
I hope I am describing this properly. This is just very frustrating. And yes, I have unchecked length snapping. I am drawing the simplest of little structures and nothing lines up, have to draw things twice or more, guidelines dont offset properly.
