Convert INP to OBD

Understanding inp and obd file formats

INP files are typically input files used by simulation software such as ABAQUS or SWMM. These files contain structured data, commands, and parameters that define a simulation model, including geometry, material properties, and boundary conditions.

OBD files, on the other hand, are most commonly associated with Open Building Designer (formerly AECOsim Building Designer by Bentley Systems). OBD files store building information modeling (BIM) data, including 3D geometry, metadata, and project information for architectural and engineering workflows.

Why convert inp to obd?

Converting an INP file to an OBD file is often necessary when you want to transfer simulation or modeling data into a BIM environment for further architectural or engineering design, analysis, or documentation.

How to convert inp to obd

There is no direct, one-click converter for INP to OBD due to the different purposes and structures of these formats. However, you can follow a workflow to achieve the conversion:

1. Export geometry/data from INP: Use your simulation software (e.g., ABAQUS or SWMM) to export the geometry or relevant data. Look for export options such as File → Export → STEP or File → Export → DXF if available.
2. Import into Open Building Designer: Open Open Building Designer and use File → Import to bring in the exported file (e.g., STEP, DXF, or IFC format).
3. Save as OBD: Once the data is imported and checked, save the project in the native OBD format using File → Save As.

If your INP file contains only simulation parameters and not geometry, you may need to manually recreate the model in Open Building Designer using the data as a reference.

Best software for inp to obd conversion

• ABAQUS or SWMM (for exporting geometry/data from INP files)
• Open Building Designer (for importing and saving as OBD)
• Autodesk AutoCAD or Bentley MicroStation (for intermediate format conversion, if needed)

For complex workflows, consider using Bentley’s iTwin Services or IFC as an intermediary format to ensure data integrity.

Summary

While there is no direct INP to OBD converter, you can transfer data by exporting geometry from your simulation software and importing it into Open Building Designer. Always verify the imported data for accuracy and completeness.
