2.20 Circle and Arc Sectors

The Circle/Arc Sectors dialogue is invoked after manual drawing of circle or polygon (i.e. using  button in the 2D Window toolbar) and allows choosing the number of sectors.

The circle is approximated by a regular polygon with the number of sides (sectors) defined by the user. A high number of sectors gives better accuracy but slightly slows down the QW-Editor operations. For example if we want to introduce an irregular octagon we first define a circle with 8 sectors and then use Edit Point operation to move each of the corners of the octagon to its proper position.
