Dimensions and Straightline bSplines

[wandererfan]

As you may know the OCC HLR algorithms delight in returning bSplines even if the edge is actually a straight line or a circle.
Starting with git commit cc320aa802 straight bSpline are treated as lines for dimensioning purposes.

This will be extremely useful, thank you.

A straight B-spline doesn't necessarily have a degree of only 1. It can also be higher.

Code: Select all

bs=Part.BSplineCurve()
bs.getPoles()
bs.Degree
bs.increaseDegree(25)
bs.Degree
bs.getPoles()
Part.show(bs.toShape())

Good to know, thanks. So far the most troublesome ones from the HLR algos have been degree = 1. Will have to upgrade the test to include higher degrees.
