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

Global

  • If you are importing PDMS design data into Smart 3D, then the DATAL/ATT files must start with SITE hierarchy information. Otherwise, the model does not import.

  • We recommend that you set the units of the PDMS model to use the same units as those used for the destination datal file that you want to import into Smart 3D. For example, if you want to import a datal file into Smart 3D that uses feet as the units, then we recommend that the PDMS model units also be feet.

Equipment Models

  • If mapping is available, PDMS equipment and subequipment are processed as catalog equipment and equipment components. If no mapping is available, PDMS equipment and subequipment are created as designed equipment and designed equipment components using their template data.

  • If mapped, PDMS primitives that are present under Equipment or SubEquipment are imported into Smart 3D as shapes. If no mapping exists, these PDMS primitives are imported into Smart 3D as uneditable GType shapes.

  • PDMS primitives that have negative primitives are imported into Smart 3D as Design Solids. There can be instances where stitching operation for a Shape might fail. So, the Shape cannot be created under Design Solids. To resolve this, a warning is logged, and the process continues.

  • If more than 50 shapes are present under an equipment or equipment component, all Simple Physical Aspect shapes are combined into a GType shape. Other aspect shapes are imported as intelligent S3D shapes. If there are more than 1000 shapes under an equipment or equipment component, each group of 1000 shapes are combined into a GType. For example, if there are 2500 shapes under an equipment, 1000 shapes are combined into one GType, 1000 shapes are combined into a second GType, and the remaining shapes are combined into a third GType.

Piping Models

  • Piping data can be imported into Smart 3D only if the DATAL file and ATT file exist in the same folder and have the same name.

  • PDMS import supports specification breaks between components. The SPRE or SPREF specification value of the PDMS component must be defined as part of the component. For example, if the run specification is A300, the SPRE value for a globe valve in the run is defined as /A150/GL-143:150, where A150 is the component specification. The globe valve feature is placed with A150, and other components in the run are placed with the A300 specification. If the SPRE value is not defined in this format, or if the component does not use SPRE or SPREF, the component is imported with the branch specifications.

HVAC Models

  • HVAC data can be imported into Smart 3D only if the DATAL file and ATT file exist in the same folder and have the same name.

Structure Models

  • PDMS primitives present under SubStructure are imported into Smart 3D as Geometric Constructions (GCs). These GCs cannot be edited or moved in Smart 3D.

  • PDMS has no concept of a multi-layer slab. When you map a PDMS material to a Smart 3D multi-layer composition, the software uses the default composition for object placement. If a default composition does not exist in the Catalog, the software skips over the slab import and writes an error message to the log file, similar to the following example:

    Skipped processing Slab: strSlabType and the Slab Composition mapped in mapping file are not present in the Catalog

  • Smart 3D cannot create openings if the negative geometry under the PDMS section intersects both the web and the flange.

  • PDMS GWall cannot be processed as a Smart 3D wall because the GWall cross section is formed by a set of points that are not supported in Smart 3D. The software imports GWalls as slabs, using the mapped slab material in the Slab Material mapping sheet.

  • PDMS import does not support wall connections.

  • Smart 3D creates a generic system for PFitting as a sibling, not as its child< of the plate system or slab. The software uses the object name to determine to which plate system or slab the generic system belongs.

Hanger and Support Models

  • Hangers and Supports can be imported into Smart 3D only when Piping, Structure, and Hanger/Support are selected under Disciplines to import in the Import Model from PDMS Datal to Smart 3D dialog box. For more information, see S3D PDMS Datal Import Dialog Box.

Electrical Models

  • Electrical data can be imported into Smart 3D only when the .datal file and the .att file exist in the same folder and have the same name.
