Modifying the Length of Schematic Lines
You can modify the length of schematic line segments using lengthen grips .Because the grips constrain
a segment to its current angle, they are particularly useful for modifying the length of schematic line segments
you have already placed.
When you use the lengthen grip on an end that is connected to another object, you must specify whether
you want AutoCAD MEP to maintain connectivity between the objects.

To modify the length of a schematic line segment
1 Select the schematic line segment.
2 Click the Lengthen grip on the end you want to modify.
3 If the segment is connected to an object on the end you selected, specify whether and how to
maintain connectivity:
then... If you want to...
proceed to the next step. maintain connectivity by adjusting only schematic
fittings and segments, and retain the current loca-
tions of parts
press Ctrl. maintain connectivity by adjusting all objects, includ-
ing parts
press Ctrl. break connectivity
4 Specify the segment length:
then... If you want to...
press Tab to activate the input field for specifying the
resulting dimension, and then enter the new length. specify the new total length
drag the cursor to begin lengthening or shortening the
segment, and then enter the change in length in the
input field that is active by default. specify the difference between the current length
and new length
drag the grip to the desired end point location, and
click to specify the point. specify a new end point
