Creating Isodraft Symbol Templates

Isodraft Symbol templates can only own STRAs, which define the geometry of the symbol, and MRKP elements, which define the start, end, spindle and tee points on the symbol. These elements should have their PURP attributes set as follows:

• STRAs owned by ISOTMs should have their PURP attributes set to LINE, INSU or TRAC (to describe whether the straight represents the pipeline, its insulation or its tracing).

• MRKPs owned by ISOTMs should have their PURP attributes set to one of ARRI, LEAV, TEE or SPIN.

The Arrive and Leave points of the symbol will be used as the reference points for dimensioning.
