The following limitations exist when exporting Smart 3D equipment, equipment nozzles, piping, structure model, and electrical data and then importing that data into PDS.

General

  • Smart 3D object names with some special characters such as € or § might not transfer with exactly the same name because the export functionality uses some of these characters for the syntax of the functionality. The possibility exists that such names will not match on both sides of the export.

  • The design file limit in PDS is 26.8 kilometers. Smart 3D objects that you have placed further than 26.8 km from the global coordinate system origin export successfully to the design file. However, the design file will not open in PDS. Before starting the export process, make sure that the modeled objects are within the PDS design file limits.

Equipment

PDS has a 30-character limit for equipment names, so the equipment name in Smart 3D cannot be longer than 30 characters. If the name of the equipment component is more than 30 characters, it is truncated during the export from Smart 3D.

PDS does not support duplicate names for equipment items. You must assign a unique name for each equipment in Smart 3D. Duplicate names in Smart 3D, or duplicate names after truncation, can cause the export process to give incorrect results.

Equipment Nozzle

  • PDS has a 10-character limit for nozzle names, so the nozzle component name in Smart 3D cannot be longer than 10 characters.

  • PDS allows duplicate names for nozzle components, as long as the nozzle components are assigned to different equipment items in the same .dgn file. Otherwise, the export process might display incorrect results.

  • Equipment piping nozzles are exported with connect point data. HVAC nozzles, and electrical nozzles such as cable nozzles, cable tray nozzles, and conduit nozzles are not exported.

Piping

  • PDS has a 20-character limit for piping component/support names, so the piping component/support name in Smart 3D cannot be longer than 20 characters. If the name of the piping component/support is more than 20 characters in Smart 3D, it is truncated during export. Similarly, piping specialty and instruments are limited to 30 characters and will also be truncated if needed. PDS allows for duplicate names for piping, support components, and instruments and specialties.

  • If an equipment or nozzle name is not defined in Smart 3D, the connection between any pipe run and that pipe nozzle is lost when the model is exported to PDS. In this situation, the pipe run starts from the connect point (the East, North, and Elevation coordinates) of the nozzle port without having any connection.

  • PDS does not support modeling of circular piping. Because of this, circular stock parts are skipped. The software writes an entry in the log file for each circular stock part.

  • Do not export pipelines with both imperial and metric specifications to the same APL file.

  • Supports that are placed at a location other than the elbow connect points are exported as connected to the elbow's center.

  • Only the specification driven attributes for pipes are transferred to sloped pipe runs.

  • To construct pipes on the sloped pipe segments, import the APL file and then enable the Automated Placement in PDS.

  • In Common application, insulation thickness is valid only when you define the insulation purpose. Define the insulation purpose in Smart 3D before you export the insulation data using Common application.

  • You can define insulation in at run level and at the component level in Smart 3D. By default, the same insulation data is applicable to components. The export process exports only the insulation data at run level. The component level insulation is ignored. However, in case of Instruments and Specialties, the component level insulation is considered.

  • The Commodity Names sheet in the mapping file maps the Smart 3D short code S3D Value and PDS commodity names short code PDS Value. To export turn features such as Elbow, Bend, Miter, and so on, append <_PIPE TURN TYPE> to the S3D Value.

    For example, to export an Elbow with a short code 45 Degree Direction Change, the S3D Value is 45 Degree Direction Change_ELBOW.

  • The Export to PDS software exports all the S3D piping supports to PDS as logical supports.

  • PDS does not support feature breaks on the pipe stock parts. Feature breaks are skipped, and the following message is added to the log file for each feature break:

    Feature breakdown is not supported in PDS, hence exporting it as stock part.

  • The software exports flex pipes from Smart 3D as specialty items.

  • The flow direction, NOFLOW, of a pipe run or pipeline is exported as UNDEFINED.

  • The Smart 3D sequence number attribute on pipe runs is not automatically exported to PDS. You can use label mapping to export sequence numbers on pipe runs. PDS has a 16-character limit for pipe run and pipeline sequence numbers, so the mapped label value of the pipe run or pipeline sequence number in Smart 3D cannot be longer than 16 characters. A mapped value longer than 16 characters in Smart 3D is truncated during export.

Structure

  • FrameWorks Plus has a 24-character limit for all structure components, including beams, slabs, columns, vertical and horizontal braces, walls, and arc members. If the name of the structure component in Smart 3D is more than 24 characters, it is truncated during export. FrameWorks Plus allows for duplicate names for structural components.

  • Slabs and solids are limited to 95 vertices (placement defining points).

  • Openings are not supported on linear or arc members.

  • FrameWorks Plus supports only circular arc members. Arc members that are created by elliptical arcs are not supported.

  • FrameWorks Plus supports only slabs or slab openings that are created by circular, elliptical, and linear elements.

  • Smart 3D does not export assembly connections to the CIS/2 file. Therefore, connection details and assembly connections are not imported into FrameWorks Plus.

Electrical

Cable object does not have any persistent graphics in Smart 3D. Hence these objects are not exported to PDS.
