trim command with circle

[flywire]

Dellus; - my sincere thanks for your effective solution. I feel that a "warning" wrt Circle trim operations should be in the Manual as such would have saved considerable time & frustration!
Thanks again, John

Working on a circle with the trim command can be confusing, and not working in the way we wish. At certain constellations it might work, at others it doesn't. A circle has a running direction, from 0 degrees (left quadrant) counterclockwise.
It's generally easier to cut it up with Divide at the desired points and delete the unwanted part.
Or draw the arc from the onset with Curve - Center, Point, Angles.
