Hole Selection Tables

Selection Tables can be created for piping, HVAC, Cable Tray and SCTN penetrations. These define selection criteria for Managed Hole GPARTS.

Managed hole catalogues, part hierarchies and selection tables are configured using standard functions provided in the Paragon module. Refer to Catalogues and Specifications manuals for instructions on creating these items. However, there are rules that must be followed when configuring this data for use in Hole Management. Catalogue data is defined as described in previous sections, with the exception that GPART elements should have PURP attribute set to PENE.

Note
That the existing standard GPART elements should not be referenced from a Selection Table, otherwise the standard holes could appear twice in the Hole Shape Selection Type field on the Hole Management Definition window. Catalogue geometry categories can be shared by Standard Hole GPARTS and GPARTS referenced by Selection Tables.

Typically, separate selection criteria will be used for selecting hole types for each of the different disciplines. The discipline is defined in the PURP attribute of the Selection tables (TABGROUP elements):

PPEN Piping hole selection table

HPEN HVAC hole selection table

CPEN Cable hole selection table

TPEN Cable tray hole selection table

SPEN Steel (SCTN) hole selection table

FIXI Panel fitting selection table

FLOO Floor fitting selection table

The description that appears in the Hole Management Definition Hole Selection Class drop-down is the description of the Selection Table (TABGROUP). It is advisable to have unique descriptions for Selection Tables within a discipline otherwise it will not be possible to distinguish between Selection Tables in the Hole Selection Class drop-down.

The description that appears in the Hole Management Definition Hole Selection Type drop-down is the description of the Selection Table Header (CTABLE). There may be more than one CTABLE in a Selection Table. The CTABLE description must be unique within that group.

Selection criteria are defined by the questions and answers on the Selection Tables. For example, the Hole Management Definition window below has selection criteria Gas Tight, Water Tight, Weather Tight and Fire Rating.

The selection criteria are defined as questions on the selection table:

The possible answers for each question are used to populate the drop-down lists on the Hole Management Definition window. Note that a large list of possible answers to a question can make the Hole Management Definition window selection gadgets difficult to use. It is worth splitting the Selection Table in several Headings (CTABLE elements) if this becomes a problem.

Cable Tray Penetration Class

Penetration fittings for cable tray penetration can be selected automatically provided that:

• The catalogue is configured correctly

• Only one penetration is made using the Hole Definition form - automatic selection does not work with multiple or merged penetrations.

The cable tray penetration selection table group must contain answers for Opening Width and Opening Depth that correspond exactly to the PWIDTH and PHEIGHT values on the penetration ATTA P-point. If a clearance is specified, 2 * clearance will be added to the PWIDTH and PHEIGHT values, and the answers will be matched with these values. If no match is found then the hole fitting must be selected manually from the list of components.

Width and depth headings in the penetration component selection table must be configured correctly for automatic selection to take place. Two headings are required; one with the purpose WIDT and the other with purpose DEPT or HEIG. When working in millimeters these headings can have real or text answers. When working in imperial units, columns with real answers must contain values in millimeters. Columns with text answers can contain values in inches if lengths are provided with unit qualifier 'in' or 'inch'. A number without units will be assumed to be a value in millimeters.
