I don't know the cause, but i can get rid of it with REGENALL.

(It rarely appeared in my drawings)

Yes sir! No clue but it's gone. Thanks

Thanks, @pendean 

These circles appeared (as far as i Know) most times after i TRIM lines (or AMJOIN with AutoCAD Mechanical).

I didn't know that hatches need to be involved.

My guess on the technical cause:

These really tiny gaps can occur due to inaccuracies caused by trimming lines (or arcs) that can't match the endpoints in coordinates used by double-float variables (which are used in every vector based program).

I guess these gaps (and therefore the red circles) appear much more often, if the drawing is placed very far from 0,0 coordinates.

Maybe try setting Gfxdx12 to 0 close and restart AutoCAD and now see if they randomly appear again

@illusionistNUGXG Red Circles in AutoCAD are built-in alerts to "something not working" within that area. More often than not they stay on screen until a REGEN or a REDRAW is executed.

If MECH does more than that, consider asking your MECH peers in that forum for additional guidance or you will need to tap Autodesk Support through your Accounts page to report the issue. But first, ensure your MECH is 100% up to date (compare ABOUT command in your MECH to the updates listed in your accounts page HERE).

Good idea, but this occures really rare (for me). I can't reproduce it to test, if the setting makes a difference.
