hatching loop
hatching loop
hello
how may i read hatching loop which is a circle? when i use looptypeat() function, it return oddbhatch::kpolyline, so i use getloopat(index,vertices,bulges), but in vertices there are only 2 points...
thanks

polyline, containing two vertices with bulges, may look like circle.
if polyline vertex has bulge, it means that segment (vertex, next vertex) is circular arc with included angle 4*atan(bulge).
sincerely yours,
george udov
