Edit Bar controls: Leave Original
This tool allows you to modify two entities, trimming them or extending them so that they join at a corner. The entities may be lines, arcs, circles or Beziers.
If you switch off the Leave Original option and you had a fillet or a chamfer in that position already, this will be removed and the corner added. If you have this option switched on, the corner will be added to the drawing, leaving the fillet in position as well. If you hold the Shift key down whilst selecting the entities then the Leave Original option will be forced on.
Pick the two entities. If the entities already intersect, be sure each pick is on the portion of the entity you wish to keep. In addition, if the entities potentially intersect in two places, you should pick close to the intersection at which you wish the corner to be created. The order that you pick the entities is not important.
If the two entities do not intersect or potentially intersect, neither entity is modified.
If you are wishing to create a corner from two arcs, or an arc and a line, which are not already crossing at the corner position, you may find it easier to extend one or both of them first. To do this, use the Extend tool (Edit>Trim>Extend) to extend them by a given distance so that they intersect. Then use the Trim Corner tool to cut the entities back at the corner.
Special Cases
One of the entities can be a construction line or circle. If this is the case, the construction entity is not trimmed back but the other is. You cannot select two construction entities.
Similarly, if one of the entities is a standard circle, it is not cut back.
You can select entities which are not in the current block but again these will not be modified.
Constraint Manager
If you have the Constraint Manager active whilst using this tool you will experience the following differences:
- A coincident constraint is added at the corner
