This tool will delete one or more rectangles. Rectangles have a point of origination and that point will not be removed with the rectangle.

Select one point on each rectangle you want to delete. It can be any of the five points, but just select one for each rectangle. Pay attention to what you are selecting as there will be no visual note of your selection.

 

The rectangles will be removed when you select Continue. Only the origination points will remain.
