About Lengthen Grips

You can modify the length of duct segments using Lengthen grips (  ). Because the grips constrain a segment to its current angle, they are particularly useful for modifying the lengths of ducts you have already placed.

When you use the Lengthen grip on an end connected to another object, you must specify whether you want AutoCAD MEP 2023 toolset to maintain connectivity between the objects when you modify the length.

Lengthen grips on duct segments

The following example illustrates how to modify the length of a duct segment. The horizontal duct segment is stretched to the right and doubled in length. Because the modification occurs in the moveable MvParts editing mode, connected objects including parts are adjusted to maintain their connectivity. More specifically, the vertical duct segment and the ceiling diffuser attached to its right branch are moved.

Lengthening a duct

Note: If the duct segment is not connected to another object, you can change both its length and angle using the Start or End grip.

The Start and End grips enable you to change the XYZ location of the start point or endpoint of the segment. This makes them particularly useful when initially designing runs because you can use them to easily connect a segment to an existing run.
