Rotating a 3-way valve 90 degrees in plan view
AutoCAD MEP displays Rotate grips on the plumbing line in-line parts , fittings, and takeoffs with connectors
on opposite ends. However, when necessary to preserve the connectivity of plumbing runs, the software
limits the available rotation options or hides the grips.
When you rotate a part, fitting, or takeoff that is connected to other objects, the software adjusts the
connected objects to maintain their connectivity. For example, the software might make minor adjustments
to the lengths of connected plumbing line segments after you have flipped a fitting. If it cannot adjust the
objects, it disconnects them.
The rotate grip turns a part 180 degrees. The flip grip orients a part (in-line or anchored MvParts, fittings,
or takeoffs) for flow direction.
Lengthen Grips
You can modify the length of plumbing line segments using lengthen grips . Because the grips constrain
a segment to its current angle, they are particularly useful for modifying the length of plumbing 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.
