creating bulge data for a polyline?
hello,
i am having trouble calculating the correct bulge data for a polyline. i understand that a bulge= tan(includedarcangle/4). however, applying this has become a problem since i do not know the includedarcangle.
i am basically trying to generate the correct bulge value from two vectors or from px and px+1 (two points) from my polyline. any help is greatly appreciated. thanks in advance.
i afraid this is not the complete function to calc the bulge value. he depends form the position of the center, too.
