Cut Surfaces
When this mode is activated, you can click anywhere on the surface of the part. With every additional click, a red line is inserted between the last two points you clicked on. That way, you can draw a line by clicking on the surface of your part. If the surface is not flat, the line may be inserted along existing triangle edges.
When you right-click on the screen, you have three options in the context menu. With Reset Line, the line is removed and a new line can be created. With Close Line, the first an the last point are connected and the line is finished. No further points can be added. If you click on the surface again, the line is removed and a new line is started.

The option Insert to mesh has two effects. Firstly, triangle edges are inserted along the drawn line and the surface is retriangulated accordingly. Secondly, the surface is split along the line, creating open border edges. Consequently, everything within the line becomes an own shell and can be selected with the "Select Shell" mode in the toolbar. If you choose "Insert to mesh" before closing the line, the line is closed automatically. If you have chosen only two points, the surface is only split along the line and no new shell is created.
