How To Use
Using the Remove tool, edges and faces can be deleted.
When the mouse cursor is close to an edge the edge will be highlighted in orange. At this time if you press the left mouse button the highlighted edge will be removed.
You can erase whichever edges you want and you can also erase multiple edges at one time by dragging the mouse.
The Erase tool can be used to merge regions sharing an edge or remove unnecessary edges.
