Description?

Hi there,
i just tried to create a circle with circle tool. If I delete points there's still a visible line. Even if copy the points of the circle and paste them into a new figure the points are connected through a straight line. Any ideas how to get it invisible?

Just try it this way:

- draw a circle
- by deleting unnecessary point create a semicircle
- Choose colour black
- activate the function of Point colour modulation
- click at the two points at the extreme ends

pay attention by deleting points of the circle. The long line between the two points at the extreme ends is probably not optimized. Try to use the optimization tool and select the extreme ends and operate the segment tool. You can also try another method. Select the circle and pull it into the windows direction. Just colour the resulting line in black.
