| Summary | 0003500: Adding Interpolating Spline feature to Sketcher/PartDesign | ||||
| Description | Good day, 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!
