FreeCAD Forum

I have this sketch: When I zoom all out some constraints are hidden, probably to not croud the display too much. That is ok.
However, when I zoom in, they are not all shown again: They remain hidden until I touch one of the lines of the sketch or one of the axis lines; here I just hovered over the upper horizontal line (excuse the size, the screenshot is taken with a different tool to show the mouse pointer): .
All this hiding and showing takes place only if there are more than one constraint associated with a certain point.
I have already a confirmation from a Ubuntu user , copied here for convenience, and I would like to see a confirmation from Windows as well.

can you upload the file?

Sorry! Done, attached to the post above.

Confirm the same experience using either 0.20 or Link branch.
Bit of a PITA having to search for constraints on the list rather than in the sketch
Strangely the common denominator so far seems to be OS?
Mine is also Ubuntu 20.04.4 LTS based...
correction:
just tried in Win10
same behaviour
later edit:
your file chrisb behaves exactly as described....

everything is always displayed for me, only pushed together in time, if I simply continue working, everything jumps back to the right place. it's not a problem in my opinion

Grouping constraints on zoom out happens every time. Ungrouping happens only on highlighting entities. Could this be the programed behavior?

Zoom all out. Then hover over some geometry of the sketch. That should hide some constraints. Now zoom in again -> they remain hidden as described above.

Hide? In your screenshots and here they are just grouped more tightly, not hidden.

Maybe, but in the second image it seems as if there are no constraints shown for the upper right point.

I was wrong in my previous observation. On zoom out grouping again happens only on highlighting a geometry item.

As in the arcs left point? The POP tangency there is grouped with the other POP tangency since they are the same type.
Here the unnumbered horizontal and vertical constraints are grouped to pre other ones with an empty string before/after the comma.
