From UBSM to SAP2000


This article explains how to send an UBSM model to SAP2000, using BIM Expert.

1. Preparation in UBSM

2. Send model from UBSM to SAP2000

2.1 From UBSM to BIM Expert

In the Model tab, select ‘Import’. Next, choose UBSM File. UBSM is BuildSoft’s neutral file format, XML based. Click  to continue.

2.2.1 Settings

Choose whether elements (material/section) to map will be showed and how the mapping should go.Select the elements to be included in the conversions. Recommended checkboxes are
  • Auto map items from database by id or name
  • Upgrade items from database to their latest versions
Click ‘Continue’ to finish the import. The model is now in BIM Expert.

2.2 From BIM Expert to SAP2000

In the Model tab, select ‘Export’. Next, choose the destination software manufacturer, namely ‘Computer and Structures, Inc’ (CSI) . Click  to continue.

Choose ‘SAP2000’

2.2.1 Settings

Select your SAP2000 version, the destination and analysis model.  The destination can be either:

  • To a new empty model in a new instance – after the file is loaded you immediately will be prompted to save the file
  • To current instance and new empty model

SAP2000 will launch automatically in case of ‘new instance’ choice.

Next, the BIM Expert sections and materials must be mapped with SAP2000’s section and materials. BIM Expert will try to find as many automatic mapping matches as possible. In case all sections and materials find a match, you will not see any dialogs for mapping.

2.2.2 Material mapping

In a new file, SAP2000 only has 2 materials present: Steel S355 and Concrete 30/37. Chances are real that you see the material mapping dialog.  If you cannot find a suited counterpart in the SAP2000 model, the material can be added as new.

2.1.3 Section mapping

A new SAP2000 model has no cross-sections. So all will be added as new.


3. Final steps in SAP2000

Depending on the chosen destination: launch SAP2000and open the file. Or continue working in the open version of SAP2000.
