Hey, I'm running into a fairly odd situation. I have a circle ( actually an approximation of a circle done with Approx.Approx_Curve3d).
The curve is parameterized from 0.0 to 1.0, and corresponds to a full circle created with this code: circle = gp.gp_Circ(gp.gp_Ax2(gp.gp_Pnt(2,2,0),gp.gp().DZ()),1); e1 = BRepBuilderAPI.BRepBuilderAPI_MakeEdge(circle).Edge(); mw = BRepBuilderAPI.BRepBuilderAPI_MakeWire(); mw.Add(e1); return mw.Wire(); My algorithm does a bunch of stuff and ends up making edges of particular portions of the circle. When I make an edge from two parameters that are at parameters 0.1 and 0.8, what I expect to get is a small segment of the circle that connects these two points along the 'shortest' path-- but in fact I get nearly all of the circle instead. I tried reversing the parameters, and MakeEdge is too smart for that-- it just creates the same edge and reverses it. The more i thought about it, the more i realized that there's really no way for MakeEdge to know i want to connect the points another way-- as far as it is concerned, the curve's start and end points do not match up. And even if they did, ( IsPeriodic() = True ), it wouldnt know whether i want the shorter or the longer path on a circle. Does anyone how i could go about constructing an edge between two points on a circular curve using the shorter path between the two?
