Enlarge
This command varies the length of the selected entities; if a positive value is entered in the special field the entities will be enlarged, whilst if a negative value is entered the entities will get shortened.
If a shortening value is inserted that is higher than the entity length, the command is not performed as it would imply the annulment of the entity in question.
If elongating an arc implies a final length that is higher than the circumference of the relevant circle, the arc is transformed into a circle.
Beware…. choosing which extreme point is to be enlarged in space depends on the point where the entity is selected: if this takes place within the first half, the first extreme point is enlarged or vice versa.
