To Modify Pipe Segments
1. Click Modify. The Modify Pipeline dialog box opens.
2. Under Active Assembly select the active assembly.
3. Under Modify Options, select Segment.
4. Under Segment, select the pipe segment you want to modify.
5. In the Segment Parameters section, modify the parameters by selecting from the list. The options are:
◦ Specification
◦ Size
◦ Schedule
6. Click OK to apply the changes and close the dialog box.
 
• If the selected pipe segment contains a reducer then the fitting modification dialog box opens.
• If a fitting overlaps because of a change in the size of the pipe segment, Spec-Driven Piping reports all the fitting overlap violations in the INFORMATION WINDOW. You cannot modify the pipeline, unless you redefine the insertion location of the fittings that are overlapping.
