ISM Import dialog

Used to import Structural members and changes to Structural members into OpenBuildings Designer from ISM (Integrated Structural Model) repository files (*.ism.dgn).

Accessed from:


SettingDescription
File > Open Opens the Open dialog with file filter set to ISM repository files (*.ism.dgn).
File > Exit Closes the ISM Import dialog without saving changes.
Settings > Logging When checked, a log file is created.
Note: This option is common to the ISM Export and ISM Import dialogs.
Settings > Revision Tracking When checked, Design History functionality is enabled for tracking changes to the DGN file. This differs from the ISM Design History tracking that occurs by default when changes are made to *.ism.dgn repository files.
Note: This option is common to the ISM Export and ISM Import dialogs.
Settings > Automatic Coping > Settings Opens the Model Coping Settings dialog which is used to define how imported Structural member types are automatically coped. Automatic coping occurs on all linear Structural members imported from Structural Synchronizer. The coping is performed on pairs of Structural members using the settings defined here.


Settings > Automatic Coping > Cope Imported Model When checked, the automatic coping is applied to the imported model.
Settings > Section Map When checked, incoming sections which do not match loaded section definitions are mapped by using the controls on the Mapping Sections dialog. While in the Mapping Sections dialog, sections can be mapped by renaming them manually or by selecting them from the Structural Sections dialog.
Note: This option is enabled only when an ISM repository file is opened.
Settings > Joist Settings Opens the Joist Settings dialog which is used to set DataGroup type and instance mappings for detailed joist members (top chord, bottom chord, and web members) that are imported along with joist envelope members.


Settings > SubStructure Setting Opens the Import Substructure Settings dialog which is used to set the name of the substructure to import. Selecting Import All will import all structural members.


The sub structure names are defined while proceeding the ISM import for a set of selected structural members in a model.
Structural Type Displays types of Structural members being imported. Selecting from the tree view acts as a filter, updating the member table.
Member table Displays mapping information between ISM definitions and OpenBuildings Designer Structural member definitions. The incoming ISM model is compared to the active Structural dataset, and then that information is used to map OpenBuildings Designer Structural member definitions to the incoming ISM definitions.
  • ISM Use - Displays the incoming ISM member definitions to be mapped to existing OpenBuildings Designer Structural member definitions.
  • Type - Displays the OpenBuildings Designer Structural member DataGroup catalog Type (Family/Part) information. Part definitions contain the Structural data information, and are defined in the DataGroup System using the string Family::Part. For instance the incoming Steel Beam type is mapped to the Steel::Beam DataGroup catalog type.Mappings that can not be determined automatically are displayed as Unset. Select from the Type pick list to map to one of the ISM usage types.
  • Instance - Displays the OpenBuildings Designer Structural member DataGroup catalog Name (section type) information. OpenBuildings Designer Structural members are selected from DataGroup catalogs. The Name attribute is used to filter out member types from the catalog query that are not related to the active placement tool or member manipulation context. For instance, the member type Steel::Beam contains a finite list of instance types: Bar Joist Envelope, Hollow Structural Section, Plate Girder, Wide Flange Beam and Wide Flange Girder.Mappings that can not be determined automatically are displayed as Unset. Select from the Instance pick list to map to one of the ISM usage types.
Import Begins the import process which includes:
  • A progress bar appears with overall import status and information about the types of members being processed.
  • Opens the Update Design Results dialog where the imported members and or changes are reviewed.
  • If Settings > Revision Tracking was checked, the Design History dialog opens.
Cancel Closes the dialog without importing.
Messages area Displays the incoming *.ism.dgn repository file name and path.
