Elliptical arc tool not behaving correctly

[Catherine Richard]

In this pattern, 4 elliptical arcs.

From Oa to E1, ok

From Ra to Qa, ok

From Qb to d4a, the arcs radii are visually reversed (that is to say, Val has taken into account 1st radius instead of 2nd and vice versa)

From d4a to Ob, the arc does not reach Ob whereas the label mentions the right 2nd angle.

Please, attach a pattern file with example.

In fact, as it can be seen in the last screenshot, 1st arc badly built too (see angle at point Oa on picture)

[Catherine Richard]

And second arc exceeds points at both sides

[Roman Telezhynskyi]

Confirm.

Catherine, your way of using the tool is wrong. The first and second radiuses must be horizontal and vertical lines. You used the same you use to define angles. This is incorrect. This you must calculate yourself.

Oh, I’m really sorry, I have understood now !!
