P-points

When you define piping components in PARAGON, you must remember the following rules so that Isodraft can produce isometrics correctly:

• P0 is automatically set and defines the origin of the component.

• For two-way components, the arrive and leave p-points must be numbered P1 and P2 (not necessarily in that order). For two-way valves, the spindle direction must be indicated by P3.

• For three-way components, the offline leg must be indicated by P3. The spindle direction for three-way valves must be specified by using a p-point greater than P3, which must have its bore unset.

• For four-way components, the two straight-through flows must have p-points P1/P2 and P3/P4. The spindle direction for four-way valves must be specified by using a p-point greater than P4, which must have its bore unset.

• For eccentric reducers without a connection point, the flat side must be indicated by P3. Eccentric reducers with a connection point must use P3, with a valid bore set, to indicate the connection point and must use P9, with bore unset, for orientation of the flat side.

• For U-bends (defined as bends of more than 135 degrees), the p-points must be set as shown for each symbol.
