Summary0004521: When joining a polygon to the end of an arc a tangent is implied
DescriptionThis feature seems to activate at imperceptible movement of the mouse or stylus. It results in an arbitrary tangent side added at whatever length fits the algorithm arbitrating between the gratuitous tangent and the new side.

A more user friendly approach might be to require a mouse click to define the tangent length.

Sorry - there was no thread to attach this to. I had a bug mid-job and needed to get it down while I could still remember how it happened.

I probably shouldn't even be here because I'm not a developer and not a professional bug fixer (any more) but merely trying to use FreeCad. Trouble is I feel an obligation to tell you about as bug when I see it even when (as it always will be) it's mid job and I'm doing something new.

A section headed 'report all bugs here' in the forum might help me - but would it help you?

I really need it to be a one step process unless you can't replicate it.

I believe the OP means "polyLINE" rather than "polyGON" -- the effect is that there is an extra segment to your polyline if your cursor is positioned too close to the arc. The logic behind this construction eludes me. IMO, the OP is right, I don't think it should behave like this: I suspect it is an actual bug rather than a feature misbehaving, but this is probably something for @abdullah to look into.

Confirm - polyLINE


Software I grew up with drew 'polygons' this way.
