Click Split to split an entity.
SPLIT divides an entity into two entities of the same (or a similar) type, leaving no gap.
The prompt reads "Entity to split:". Select the entity you wish to divide.
The prompt reads "Split entity at point:". Select the split point. If you do not select a point directly on the entity, the point will be projected perpendicularly to the entity (or the entity’s tangent).
CC3 creates two entities, even though you can't see the place where they join, and terminates the command.
To restore the original entity:
Use the UNDO command (Edit> Undo).
