Join; Lengthen - Autodesk 235B1-05A761-1301 - AutoCAD MEP 2010 User Manual

In AutoCAD MEP, you can use FILLET to fillet not only AutoCAD objects, such as lines, polylines, and arcs,
but also schematic lines and plumbing lines. By using FILLET with a fillet radius of zero (default), you can
easily connect schematic lines or plumbing lines by extending or trimming them. You can use the command
in orthographic mode
Filleting plumbing lines
NOTE The resulting single schematic line or plumbing line has the properties of the segment that you select first,
such as system, style, and flow direction. In the case of plumbing lines, the resulting plumbing line also has an
elbow of the type specified for the plumbing system. For more information, see
a Plumbing System Definition
For more information about the FILLET or EXTEND commands, see the AutoCAD Help.

JOIN

The JOIN command joins similar objects to form a single, unbroken object. You can also use it to create
complete circles and ellipses from arcs and elliptical arcs.
In AutoCAD MEP, JOIN only works on AutoCAD objects, such as lines, polylines, arcs, and splines. However,
you can join duct, pipe, cable tray, or conduit segments, as well as plumbing lines, by merging them. You
can also connect plumbing lines or schematic lines with the FILLET command.
For more information, see the following topics:
Breaking or Merging Duct
Breaking or Merging Pipe Segments
Breaking and Merging Cable Tray or Conduit Segments

LENGTHEN

The LENGTHEN command changes the length of lines, polylines, arcs, and splines and the included angle
of arcs.
In AutoCAD MEP, LENGTHEN does not work on duct, pipe, cable tray, or conduit segments. Rather, you
can use Lengthen grips to modify the length of segments. Depending on the editing mode you select, the
grips move or lengthen connected objects to maintain their connectivity.
