OpenBuildings™ Station Designer Help

Import from STAAD.Pro

Used to import data from the STAAD.Pro analysis program back into your Structural model.

Accessed from:
  • Backstage: File > Import > Structural > STAAD Import
SettingDescription
General
  • STAAD.Pro File Name - Displays the imported *.std file name. STAAD.Pro files on disk can be selected by clicking [...] (browse).
Revision Tracking Contains revision tracking controls to specify OpenBuildings Station Designer's actions after you import structural data from STAAD.Pro to OpenBuildings Station Designer.
  • Use Design History — When on, Design History is used to track revisions. When off, Design History is not used.
Roundtripping Options
  • Ignore End Point Changes — When on, dissimilar imported points are ignored, and Merge Tolerance is not applied.
  • Merge Tolerance — Represents a distance in which points with similar coordinates are merged. If a model created in one coordinate system is imported into a system with its own coordinates, points that do not coincide exactly are merged based on the Merge Tolerance value entered. This value is measured in master units. If the member endpoints in the imported file have been changed, and exceed the tolerance value, the translator detects them as changes. The Update Design Results dialog displays the change information in the Changes column an "Analytical Endpoints Changed" message.
Section Mapping Contains controls used to activate and specify Section Mapping between OpenBuildings Station Designer and STAAD.Pro.
  • Use Mapping File — When on, a section mapping file is used to map the section definitions to corresponding definitions in STAAD.Pro. The mapping file resolves known differences between how sections are defined in OpenBuildings Station Designer and STAAD.Pro.

    When off, sections are translated without any Section Mapping. The sections must be resolved later if mismatches or incomplete definitions exist.

  • Section Mapping File – Displays the path and file name for the section mapping file to be used. You can browse for a section mapping file by clicking [...] next to the Section Mapping File path. This opens the Select Mapping Files dialog to a location where several default section mapping files are provided for external analysis programs supported by OpenBuildings Station Designer. Or you select your own mapping files.
Steel Elements Contains controls to define structural data such as catalog type and catalog instance assignments for steel members imported from OasysGSA. Information about steel section definitions applied to imported concrete members is also manipulated here. These assignments are important for accurate translation of member data between analytical programs and OpenBuildings Station Designer. The following Structural elements are applicable:
  • Beams
  • Bracing
  • Columns
  • Plates
  • Default Section Name - Displays the default section name assigned to imported members whose section definitions are unknown. Select the down arrow next to the text field opens a section chooser that allows you to select from recently referenced sections or from the available section libraries.
  • Verify — Click to scan the imported section definitions. All unrecognized sections display in the Unknown Sections dialog. You may write these unknown section definitions into the session's active section file. Otherwise the unknown sections are replaced with the chosen default section.
  • Import Physical Model Only - When on, the physical model in the imported STAAD.Pro file is separated from the analytical model. Only the physical members are imported.
  • Catalog Type — Selects the catalog type information to be mapped to incoming Structural steel members. Catalog type definitions contain the Structural data information, and are defined in the DataGroup System. For instance the incoming Steel Beam type is mapped to the Beam | Steel catalog type.
  • Part Instance — Selects the catalog instance information. Structural members are selected from DataGroup catalogs. The Instance 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 Beam | Steel contains a finite list of instance types: Bar Joist Envelope, Bar Joist Members, Beams, Lateral Beams, Lintels, Opening Framing, Plate Girder, Purlins, Tapered Beams.
