This option activates the Interference Checker Data form, which allows you to make the envelope-building process and the interference-detection process more specific. The following examples will be better understood once you have read all of the command descriptions.

There are many ways to specify the interference-detection process. You can define an interference matrix that specifies which disciplines are checked against each other. For instance, for all Equipment design areas, you can define a matrix that would only check Equipment design areas against Piping design areas and against Equipment design areas.

In a different situation, you may decide to use the No Intra Discipline Interference Check command to specify:

  • Models in the specified discipline are NOT checked against each other and are NOT checked internally.

  • Models in the specified discipline are checked against models from all other disciplines.

  • All models from all other disciplines are checked against each other.

Along with the No Intra Discipline Interference Check command, you can also specify dual-design area ownership. (See the Single (1) Design Area Ownership / Dual (2) Design Area Ownership discussion on the following pages for more information.) Dual-design area ownership ensures that only the design areas that own a component involved in a clash can own the clash. Therefore, with the combination of No Intra Discipline Interference Check command and dual-design area ownership, the interference-detection process would be as follows:

  • Models in the specified discipline are NOT checked against each other and are NOT checked internally.

  • Models in the specified discipline are checked against models from all other disciplines.

The third part of the No Intra Discipline Interference Check command (all models from all disciplines checked against each other) would not be used; dual-design area ownership specifies that a design area can only own a clash if it owns at least one of the conflicting components.

The possibilities are limitless. You can combine all of the Interference Checker Data options to specify the exact interference-detection process that is needed.

Commands

Single (1) Design Area Ownership / Dual (2) Design Area Ownership – This toggle allows you to detect clashes when more than one design area needs to own, review, or approve a clash. For more information, see Single/Dual Design Area Ownership.

Exclusion of Interferences by Discipline – This option allows you to specify how clashes are to be reported for combinations of disciplines. For more information, see Exclusion of Interferences by Discipline.

Exclusion of Interferences by Model Status – This option allows you to specify a low and high model-status range. For more information, see Exclusion of Interferences by Model Status.

Equipment without Insulation / Equipment with Insulation – This option allows you to specify whether or not insulation is to be included as a factor in clash detection. For more information, see Equipment without/with Insulation.

Construction Tolerances for Equipment Envelopes – This option allows you to enable or disable construction tolerances. For more information, see Construction Tolerances for Equipment Envelopes.
