The File > Import > Structure > Bocad command imports a Bocad® .bti file into Smart 3D.

Import of Attributes/Properties

Attributes that were defined in bocad and exported can be mapped and imported to Smart 3D properties using the sample UserAttribute_Map.xml file. These attributes are included in the BOCAD_Master_Physical_Map.xml file. This file is delivered with Smart 3D in the [Product Folder]\SmartPlantStructure\Symbols\StructureImportExportMaps folder.

If the bocad attribute that you want to map does not have an equivalent property in Smart 3D, you need to add that property to Smart 3D (using bulkload) before you can map to it in the xml file.

If the bocad attribute does not have an entry in the mapping files but a property with the same name exists in the Smart 3D, then that third-party attribute imports and populates the Smart 3D property even though it is not in the mapping file.

Member Orientation and Member Type

The physical orientation of the member determines the member type during import.

  • If the bocad member name exactly matches an existing member type defined in Smart 3D, then the software sets the member to that member type regardless of orientation. For example, if a member has an orientation greater than 10° from vertical but is named "Column", the software imports that member as a column despite the member having an orientation of a vertical brace.

  • Members that are vertical or within 10° (1/10 slope) of vertical import as columns.

  • Members that are horizontal or within 10° of horizontal import as beams.

  • Members that are between 10° of horizontal and 10° of vertical import as vertical braces.

  • Members are never imported as horizontal braces as there is no way to distinguish horizontal braces from beams. You must manually edit the members that are horizontal braces after import and set the correct member type.

  • All curved members import as beams.


  • Curved members are imported using the resolution defined in the import file.

  • Built-up members are imported if the mapping file is defined to do that.

  • Previously imported structure is not updated on subsequent imports. In this situation, either that structure is skipped, replaced, or imported as a copy depending on the import option chosen.
