[ Ticket #4144 ] Sketcher: Point-point-point symmetry: order of points?

Postby Roy_043 » Tue Sep 24, 2019 5:34 pm

If I click the tool first the required order is:
PtA-Center-PtB
If I click the tool last the required order is:
PtA-PtB-Center

Why is the point order different?

I can't tell you why, but it is known and has been discussed in the past. However I'm not sure any further decision/action has been taken, thus great you reopen that topic. :)

Dammit! This is what I hate about FreeCAD, people "know" things, but don't document them anywhere, Sketcher ConstrainSymmetric.

issue #4144.
Great but could be good to poll community for the preferred order. ;)
For me, I prefer in "topological order", thus with the point of symmetry as 2nd click. ;)

This order may be more convenient (and it is already available for creating symmetry with a line in the middle).
But I vote for the more systematic order where the symmetry point is selected last.

I would also prefer the "topological order", as mouse movements are shorter, thus faster.

If there is no consensus, a preference-controlled order can be a way to go. Then we'll have the same discussion on what order should be default. :P

No parameter on my behalf, I can live with either decision. I don't even need a majority. It shalll be what Abdullah decides.
