I. Function Introduction:

Edges of board pieces can be selected for notching.

II. Problem-solving:

Solve the problem of difficult and multi-step operations for notching the edges of board pieces in the past (for example, in the demonstration plan, the old notching method requires adding 4 vertices, setting coordinate values for each of these points, and then setting the point type to achieve the goal).

III. Graphic and Text Operating Steps:

(1) Open the customization plan;

(2) Switch to the board piece selection mode (or press the shortcut key B);

(3) Click on the board piece, select the edge to be notched, click on the notching, and set the notching parameters.
