From a QCAD user:
How can I split a circle up into line segments / interpolate a circle using line or arc segments?

1. Select the circle(s)
2. Modify > Split Entities
3. Enter the number of segments in the options toolbar and click the checkmark to apply
-> Your drawing now contains many small arc segments instead of the original circles
4. Draw > Polyline > Polyline from Segments
5. Click the segments shaping circles created in step 3 to convert them to polylines
-> Your drawing now contains polylines with small arc segments instead of the original circles

To convert these polylines with arc segments into polylines with line segments, you can use:
6. Draw > Polyline > Arc to Line Segments
-> Your drawing now contains polylines with small line segments instead of the original circles

From polylines to circles

It would be great if it works the other way around as well. So that circles, semicircles or ellipses are automatically created from polylines. This could save a lot of work, especially when working on third-party drawings. Is there a chance of realization?
