Perform Addition
Use the Perform Addition option to combine two block models based on a block model definition file (.bdf) and a variable constraining file (.bcf) created through the Addition Parameters option. For more complex constraints, the (.bcf) file can be created through the Manipulation > Edit Script option.
- The two block models must have the same orientation (angle, plunge, and dip).
- Combining a Classic block model with an Extended block model will always result in the creation of another Extended block model. The only way to create a Classic block model is to combine two existing Classic block models. Use the Convert Classic to Extended option, or the
bconvertexecutable, to convert the block model. - This option cannot be used with block model files that were constructed through the Create Stratigraphic Solid option (under the Block > Construction submenu).
This option utilises the Corporate Standards settings. For more information regarding the functionality of Corporate Standards, please refer to the Corporate Standards section.
The 
Corporate Standards button will only be displayed on panels if the VULCAN_CORPORATE environment variable was defined during the installation of Vulcan.
