OpenVSP maintains uniqueness for all parameters in all components of every model. You can quickly view the details of every accessible parameter in your model by clicking on the Name of that parameter in the GUI box. For example, to view the Span parameter of a Wing component, click “Span” in the Sect tab. You can use the information shown to identify the Name, Group, Max/Min, etc. as well as Links and Advanced Links for that parameter. OpenVSP also allows you to quickly populate variable selection areas by dragging-and-dropping the variables. You only need to click and drag the variable name (button) to the variable selection or add region and then drop. VSP will either automatically select or add the parameter depending on where you drop. This feature is exceptionally useful for variable selection operations within Design Variables, Variable Presets, and Linking.
