There are several grips you can use to modify components:
Available on Description Grip
ducts, fittings, and MvParts Starts the Add Ducts command; allows you
to draw new runs directly from the grip loca-
tion add
ducts, fitting, and MvParts move a part location

in-line or anchored MvParts, fittings, and takeoffs rotate a part around a duct centerline; also
flip parts in place, usually to orient a part for
flow direction rotation
