The third and fourth illustrations show other fittings connected to the pipe end. If a coupling is added, the midpoint of the coupling is located at the original pipe end location. The pipe end is moved to the adjacent coupling face. An elbow is added at the end of the pipe, and the pipe end stays in the same location. The pipe length stays the same, but the cut length increases because the elbow CEL is added to the length. For each of the connections shown, the resulting pipe cut lengths vary from the original pipe length. Cut length with grooved connections are reported differently. Due to their design geometry, grooved coupling connectors are located inside the coupling at their CEL on page 267 depth. Unlike other connection types, pipe ends insert into grooved couplings. Joints and fittings have the following effect on pipe segments and cut length: ■ When modifying pipe segments using lengthen grips on page 276 and dynamic dimensions, the dynamic length dimensions do not include CEL values. ■ If you are working with a specific pipe length in a system, such as a stock length and you add or change a fitting, this might affect the cut length of a pipe segment. Pipe Snaps Pipe snaps quickly and accurately connect pipe objects. As you draw a pipe, you can use pipe snaps to connect a pipe, fitting, or MvPart directly to a pipe end connector at the end of a pipe segment. You can also connect to pipe curve connectors at any point along a pipe segment. Pipe end connector Pipe curve connector RELATED For more information see Using AutoCAD MEP Snaps. Pipe Elevation Lock You can lock pipe elevation as you draw a horizontal pipe run. By restricting the pipe run to a specific elevation, you can avoid unintentional snapping to another object at a different elevation. When you want to connect a horizontal run to a vertical segment, locking the 270 | Chapter 7 Drawing Piping Systems
