Thanks for the detailed description. Worked exactly as you described. Will use this method in the future and probably will never come up with an open contour again :) Just wanted to add: I don't like "trim both" as a solution despite from disliking trimming in general. I preferred to give the deteri...

Zooming to the correct point of interest is an issue… zooming in too much loses any control. Maybe easier to control .... Use the hatch tool to find the issue - if the loop is not closed it will tell you in the command line e.g. "Loop not closed at point 96.6/89", select the coordinate 96.6/89 and ...

Your error is highlighted me thinks But I can not see any discontinuity when I zoom in. How did you discover it? Or is yours the corrected version? 44.98 vs. 45 for the Y-Coordinate? Sorry for delay... yes, my version is corrected. I hunted. I tried hatch and found the unmatched coordinates. It was...

Same contour again... In your dxf. Draw / Polyline / Polyline from Segments OG. Tolerance very low but larger as 1e-6 eg 0.00001. Simplify No. Point at lefmost vertical. Qcad will find all properly connected and create a Poly string. Where such a string halts there may be a problem. Your string loo...

Thought I had solved it but laser cutter vendor software still says there is more than one contour (due to outer possibly open).

Thought it would be easy but can't figure out at the moment how I can copy a selection from one layer to the same position into layer 0 (or another one)? EDIT: I copied the layer once, deleted everything despite the items wanted, then changed the selected items to layer 0 and deletd the copied layer...

Same reproducable erroneous behavior on Windows 10 x64 QCad 3 .23.0.0. So it's probably not a macOS/Mac Qt issue.

Can't confirm, please attach file before D2

Here goes...

It is attached.
BTW, I tried it out with day time theme, (opposite of dark theme) because I had problem with other program in conjunction with dark theme but it is not the case here.

Would be glad if someone could confirm it.

Question: Do you use the grid to design your drawing?

No longer. When I was making my first steps in QCad I did but I abandoned and took grid snap out of my autosnap list.

Open a new drawing draw a circle center point 0;0, radius 1.2 draw an infinitesimal horizontal line through center and right reference add a second layer1, color orange, activate this layer draw a vertical infinitesimal line through center of the circle activate layer 0 select D2 and break out upper...

I drew a full circle in layer "new" and did a D2 on the lower half circle. As a result a white (layer "new") spot, length 0.000106 remains. Will be detected by "find zero lengths".

With all these findings you detected, do you think that I ever constructed these deviations by myself? Or isn't it Qcad destructing my drawing through moving entities around (e.g. copy/paste from another DXF)? I'd better start constructing the part again from ground up and watch when it starts to ge...
