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

Post by Roy_043 »

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.

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.

In either scenario (selecting the tool first or the geometry first), the resulting input to the software is the same (two points and a line). The most user-friendly approach would be to have the order not matter - the user selects the geometry in any order and the software intelligently sorts things out. Even if you prefer one order over another, you'd get what you want with this approach. Win, win, win. :)

No. The topic is about point-point-point symmetry. But there has been another discussion and even a vote about PPP symmetry.
