Polyline: Change Points (Sketch)

Insert

Divides lines by inserting additional points.

If you have identified the first segment of a polyline, you can select whether you want the point to be inserted as a new start point or the edge to be divided by the new point. The same applies to the last edge.

Multiple points

Inserts null edges at the end of a segment of the polyline.
This changes the total number of points and edges of a polyline, but the geometry is preserved.

This function is useful, for example, if you want to create freeform surfaces by connecting two polylines with different numbers of edges. In this case, you can already define the null edge here.

Merge

Deletes individual points of a polyline.

Select the points to be deleted by identifying the corresponding edges near the point in question. Choose ESC (middle mouse button) to end the selection of points. The edges are re-connected via the corresponding adjacent points.
