Polyline How To

[Anonymous]

I want to draw a complex polyline with both arcs and straight lines. I look at the polyline constructor and see that I can give the vertices for the polyline. but, how can I set whether the vertices connection a line or and arc?

I'm not finding much in the way of documentation on the polyline functions.

Can someone direct me to examples or documentation? Please?

I wait that this you is useful

Dim pline As New Autodesk.AutoCAD.DatabaseServices.Polyline()
pline.AddVertexAt(0, p0, 0, 0, 0)
pline.AddVertexAt(1, p1, 0.414214, 0, 0)
pline.AddVertexAt(2, p2, 0, 0, 0)
pline.AddVertexAt(3, p3, 0.414214, 0, 0)
pline.AddVertexAt(4, p4, 0, 0, 0)
pline.AddVertexAt(5, p5, 0.414214, 0, 0)
pline.AddVertexAt(6, p6, 0, 0, 0)
pline.AddVertexAt(7, p7, 0.414214, 0, 0)
pline.Closed = True

Thanks, that did help. I didn't quite understand that bulge meant arc segment.

It sounds more like a line width or something.

Anyway, thanks a lot. I've got a much better understanding of polylines now that I understand the bulge property.


I'm still curious about how you arrived at the bulge value of 0.414214. It works, for what I want but I'd be eager to learn more about calculating bulge values for different effects.

Perhaps annexed images can help.
