Point Editing Mode enables user to edit or modify just a single point of the project. To enable this mode, you need to right click on any part of the drawing area. A menu will pop up (Context Menu)
Once enabled you will notice a couple of thing. First the cursor change.
The next thing is the image of letters. You will notice that every point has a circle. Once you move the mouse you will notice that the closest point will turn into a diamond.
To edit any point all you need to do is click and drag the particular point.
