Below are the steps to create a Substructure or Superstructure model:

• Open OBD and open your OBDX file
• As shown in the screenshot below:
  • Choose the Standalone workflow; by selecting Standalone, not the Default BIM Workflow,  at the top right of the Standalone File Groups screen
  • Create a new Standalone Group; by clicking on the yellow folder button with a green plus, at the very top right of the Standalone File Groups screen 

 

• Go to the Analysis tab and launch LEAP Bridge Concrete (LBC):

 

• If you want to open an existing Substructure only file click on File > Open and open the existing file:

 

• If you want to start a new Substructure model then from the Substructure tab launch Substructure module and build your model as you did in the past.
• Click on File > Save and give the model a name:

 

• You can close the Substructure module and LBC and you will see the saved model shows in the OBDX file:

 

• When you want to continue to work in the file, open the OBDX file and select file you want to work in and launch LBC it will open the file you had saved:

 

 

OBS.:  Please make sure to add Project notes in the superstructure or substructure module Project area, and not in the main LBC Project area.

NOTE: Check the link below about the specific procedure to save only the substructure model in OBD:
