This parameter indicates whether to fix angles of equal-width lines. If this parameter is not selected, no angles will be smoothed.

This parameter indicates whether to fix bottleneck caused by lines of equal or unequal widths. If this parameter is not selected, no bottlenecks will be smoothed.

===========================================================

The following table summarizes the behavior of the Fix Angles and Fix Bottlenecks parameters, where r1=r2 means both lines are the same width.

Fix angle Fix bottleneck r1=r2 Action
Y Y Y Fix angle and/or bottleneck
Y Y N Fix angle and/or bottleneck
Y N Y Fix angle
Y N N Do nothing
N Y Y Fix bottleneck. Fuse if they almost meet
N Y N Fix bottleneck (use arc if there is an angle)
N N Y Do nothing
N N N Do nothing
