Description Robert Großkopf 2018-11-09 10:05:56 UTC
Created attachment 146488 [details]
Document shows 2 circles 13cm radius. The circles do not coincide.

Open Draw.
Draw a big circle with Shapes > Circle.
Copy this shape.
Insert so you get two shapes.
Turn the circle 45 degrees.
First and second circle aren't the same. The circle isn't circular.

Tested with LO 64bit rpm Linux.

6. Press F4 for the second circle
7. Go to rotation tab & rotate the circle 30 degrees (or something else)

I'm going to use a 12-segment solution instead of the current 4-segment solution.

It is not perfect, but is much better than in 6.0.

The follow up issue for increasing accuracy of circles and arcs in general is bug 121425.
