1.6.1.3.2.18.  Sketcher: Group elements into a spline

With V12, via function Group elements into a spline, single arcs can be grouped into a spline. (Feature only for demo purposes, not released.)

If a part has a curve with variable radius, you have to approximate their form by using several single arcs (Arc through 3 points on circle, see following figure). Now the spline feature enables to export a grouping instead of single arcs. As a result the error rate is reduced, especially when using the blend feature. Furthermore the depiction in 3D is more precise.

First single arcs are drawn and then the spline feature is used.

  1. Draw the curve of single arcs

  2. Pick the start point of the curve

  3. Pick the single elements to be grouped into a spline one after another.

  4. Pick the end point of the curve
