|Summary||0003500: Adding Interpolating Spline feature to Sketcher/PartDesign|
Some time you want to interpolate a curve through some measured key points (that should be controlled/constrained as normal sketcher points) an in this case the control over the order of curvature / knot weight is less important.
These splines are similar to the b-spline tool in draft WB, even if it might be more accurate to call them centripetal / Catmull-Rom splines
They do have a lot of really interesting properties for modeling:
- they are nicely behaved, stay local and never diverge/loop even when control points are close together,
- you can also set the tangent at the beginning/end to connect with the rest of sketches elements
- possible to generate close loop with them.
But the most important feature is you control the curve with way points, not knots like B-Splines/NURBS that have no relation with the end result curve.
Thanks for your hard work!
