Convert model from SBEM v6.1 to v5.6
Posted by Luis Sousa on 27-Jan-23 05:01 PM

DesignBuilder does not support forward compatibility and this means that it's not possible to load models saved in newer versions into older releases. 
See: DesignBuilder dsb file version compatibility

The workaround to move the geometry to an older version is: 

1. Open DB v7.1 and load the v7.1 model,

2. Export the geometry using the Export gbXML model option (File >Export)
See image below:




3. Uninstall DBv7 and install DBv6.1, and create a new project,
Here is the link to the installer DesignBuilder v6.1.8.021

4. Import the geometry using the Import 3-D model toolbar option and select the previously saved gbXML file.

See image below:


5. Set the Geometry template to reinstate the zero wall thicknesses.



6. Enter the SBEM input data again (Construction, HVAC, Lighting, etc.)
