The following limitations are known to exist when exporting Smart 3D piping, equipment, HVAC, hangers and supports, structure, and electrical data and then importing that data into PDMS.

Global

  • When exporting a hierarchy, a recursive user-defined element type cannot be created in PDMS. For example, if a piping system (PIPE) is created once, it cannot be its own parent or child, but it can be a sibling.

  • If you set the .ini option ExportHierarchyAs in the PDMSExportTranslator.ini file to MULTI_SITE, the PDMS software may not list some of the objects under the selected filter. To avoid this, we recommend that you select Generate separate file for each discipline in the S3D PDMS Model Export dialog box, and then export the filter.

  • If you set the .ini option ExportSupportsAs in the PDMSExportTranslator.ini file to ATTACHMENT_MAPPING, and if the support is connected to any structural member in Smart 3D, then no connection is established with the structural member in PDMS.

  • The number of pipe attachments exported to PDMS is greater than the number of supports in Smart 3D because mapping is performed at the support component level.

Equipment Models

  • If the catalog is not set up or if mapping is not provided for an object, the software breaks the object into GTypes and objects and then exports them as primitives. As such, the equipment item may be difficult to modify after it is imported into PDMS.

  • Imported shapes are placed under a sub-equipment element (SUBE), but they should be treated as primitives because they are shapes in Smart 3D.

  • In the current release of the software, the catalog equipment component is transferred only through GTypes. Mapping is not supported.

Piping Models

  • Because there is no concept of on-the-fly specialty components and on-the-fly instruments in PDMS, these Smart 3D piping objects must be created as explicit components in PDMS. It is assumed that there is one on-the-fly specialty component or instrument for every different end preparation, pressure rating, schedule thickness, and end standard.

  • By default, supports are exported only as logical supports. If the .ini option ExportSupportsAs available in the PDMSExportTranslator.ini file is set to ATTACHMENT_MAPPING, then supports are exported as PDMS pipe attachments in the PDMS piping isometric drawing output. The pipe attachments have the physical geometry of the supports.

  • No bolt sets or washers from the model are transferred from Smart 3D to PDMS. These are considered implied items and the catalog should be set up properly before the export process is started. Bolt lengths, bolt diameters, and number of bolts should match the Smart 3D data.

Structure Models

  • The software sets the attribute for JLine and MLine on sections and joints to NA (Neutral Axis) by default.

  • Cuts on members and objects created during assembly connections are exported as fittings. Negative geometries are created for cuts, and panels are created for additional objects.

    Export using catalog joints is not supported in the current release of the software.

  • The software breaks stair, ladder, and handrail symbols, as well as footing and equipment foundation objects into GTypes and exports them as primitives under the STRUCTURE element.

  • The software breaks stair, ladder, and handrail items that have been converted to intelligent structural objects into equivalent intelligent items under the STRUCTURE element.

  • Curved plate parts on both plate systems and built-up members are exported as smaller triangular planes which make-up the total curved surface.

  • The hole fitting object on the planar plate part is exported as a panel fitting under the PANEL element (planar plate part). Curved plate parts are exported as SUBSTRUCTURE, because the PANEL element is not created for a curved plate part.

  • Openings, trim, corner, and end cut features on the profile part are not exported.

  • Twisted stiffeners are exported by breaking the profile part into primitives and exporting them under the SUBSTRUCTURE element.

Hanger and Support Models

  • If the catalog is not set up or if mapping is not provided for all hanger and support Components present in Smart 3D, then the software breaks the object into GTypes and exports them as primitives.

  • The software assigns support GTypes as SCTN attributes in the PDMS structure hierarchy. The software does not export the Smart 3D hierarchy to PDMS.

  • Because the export of hanger and support model data is dependent on structure model data, the structure model data must be imported into PDMS before the hanger and support model data.

HVAC Models

  • Supports are exported only as logical supports and appear as attachments in the PDMS isometric drawing output.

  • No bolt sets or washers from the model are transferred from Smart 3D to PDMS. These are considered implied items and the catalog should be set up properly before the export process is started. Bolt lengths, bolt diameters, and number of bolts should match the Smart 3D data.

Electrical Models

  • If the catalog is not set up or if mapping is not provided for an object, the software breaks all electrical objects into GTypes, and exports them as equipment objects for space reservation purposes only. Consequently, an equipment item from PDMS can be difficult to modify after it is imported.

  • Imported geometries are placed under a sub-equipment element. The behavior of the imported data can be correlated to equipment designs of electrical objects.
