# Lengthen

Changes the length of objects and the included angle of arcs.

You can specify changes as a percentage, an increment, or as a final length or angle. LENGTHEN is an alternative to using TRIM or EXTEND.

### Delta

Changes the length of an object by a specified increment, measured from the endpoint that is closest to the selection point. Delta also changes the angle of an arc by a specified increment, measured from the endpoint that is closest to the selection point. A positive value extends the object; a negative value trims it.

### Delta Length

Changes the length of the object by the specified increment.

### Angle

Changes the included angle of the selected arc by the specified angle.

### Percent

Sets the length of an object by a specified percentage of its total length.

### Total

Sets the length of a selected object by specifying the total absolute length from the fixed endpoint. Total also sets the included angle of a selected arc by a specified total angle.

### Total Length

Lengthens the object to the specified value from the endpoint that is closest to the selection point.

### Angle

### Dynamic

Turns on Dynamic Dragging mode. You change the length of a selected object by dragging one of its endpoints. The other end remains fixed.
