To delete an edit point on an curve entity (line, polyline, curve, or combination)
1. Select the Curve-Delete Point command.
2. Position the cursor over the edit point to delete and click the left mouse button.
3. Repeat step 2 as many times as you want. The Delete Point command will stay active or current until you select another command.
Note 1: You can also use the Point-Delete Point command to delete points from a curve entity.
Note 2: You can delete any point in any curve at any time. You do not have to pre-select the geometry before using this command.
Note 3: If you delete one of the points in a two point line, then the program will delete the curve entity. It will not convert the remaining line point to a point entity.
