NOTE When a fitting is required but it cannot fit the layout, plumbing lines are inserted. For example, the next illustration shows 2 instances where elbows could not be inserted, and so the software inserted plumbing lines instead. In designs that require unique fittings (common to piping or plumbing), you can override the default fittings or you can add a fitting manually. You can create plumbing fitting styles based on information such as type (i.e., tee, cross, trap, or check valve) and subtype (i.e., 45-degree mitered, 90 degree long-radiused, or 3-way). The style determines the appearance and function of the plumbing fitting. Styles provided with the software include Cross and Sanitary Tee. While you can manually create elbow fitting styles, the software automatically creates them as you design your layout. The software inserts elbows and then adds corresponding elbow styles to the drawing as needed. The type of elbow you specify as the default for the plumbing system, in conjunction with the angle of the elbow that is added to the layout, determines the name of the elbow style (for example 60 Degree Standard Radiused Elbow). Associative Movement You can move MvParts, fittings, or plumbing segments without breaking their connections with the rest of the system. Used in conjunction with certain grips, the associative movement feature enables you to move a plumbing run component quickly and accurately. For example, when you move an MvPart to a new location, the plumbing segments attached to the MvPart can move, shrink, or stretch to maintain a connection with the system. You can also move a plumbing segment without affecting the location of MvParts or other portions of the run. Movement of a Plumbing Line Segment The following example shows a plumbing line that is moved. The fittings connected with the plumbing line move with it. However, all other components in the run remain fixed in their original position. 466 | Chapter 10 Drawing Plumbing Systems
