Piping Clash Check - PDS - Help

Plant Design System (PDS) Piping Design Graphics (PD_Design)


This command checks a pipeline or user-defined active groups for interferences immediately after completing the line. It automatically creates interference envelopes in memory for any piping in the selected pipeline or active group. It checks any attached reference models for which interference envelope files have been created previously. It also reports any reference models for which interference envelopes have not been created previously.

The results of this interactive clash checking are not maintained as a part of the Interference Management data. However, you can use the Piping Clash Review option to review the clashes detected by this command.

Construction tolerances and angular tolerances (tolerance for recognizing horizontal beams for determining when piping is legitimately resting on steel) are considered during the interference checking process.

The sparse version of the structural model is used when creating interference envelopes. Model management data must be loaded for the sparse structural models through the Project Environment Manager. In order to review clashes between piping and structural models, attach propagated structural models instead of sparse structural models.

This command does not affect the interference envelopes created by the Interference Manager's Envelope Builder.
