OFFSET

The OFFSET command copies a selected object, giving the copy a shape that reflects the original. Because
OFFSET offsets polylines, in AutoCAD MEP you can use it to offset schematic lines.
You can also use this command to offset individual segments of duct, pipe, cable tray, or conduit, and
individual plumbing lines. However, because the command does not support the selection of multiple
objects, you cannot use it to offset a complete run.
For more information, see "Offset an Object" in the AutoCAD Help.

PURGE

The PURGE command removes unused, named AutoCAD objects, such as blocks, layers, and styles, from a
drawing.
Because PURGE purges only AutoCAD objects, in AutoCAD MEP you should purge unused building systems
objects first, and then use the Style Manager to purge unused system definitions.

ROTATE and ROTATE3D

The ROTATE command rotates an object around a base point. The ROTATE3D command rotates an object
around a 3-dimensional axis.
In AutoCAD MEP, you can use ROTATE3D to rotate fittings around a specified axis and connection point.
However, a quicker and easier alternative is Rotate grips. In plan or isometric views, you can use Rotate grips
to rotate both fittings and inline parts. The grips adjust connected objects and maintain their connectivity
whenever possible.
