Lock cursor horizontally or on wall plane

This function can be used to change the method of locking the cursor when adding or editing a window or door in a 3D model. As a default, the cursor is locked horizontally, so the opening can be moved across the wall at the default height or the positioning height you have determined. By clicking this button, you can lock the cursor to the wall, so you can position the opening on the wall at any height you like.

1. Change the locking method, if necessary.
2. Select the location of the opening.
