Similar to isolating OpenVSP components in Sets for analyses or visual grouping, you can also define specific sets of components to be included or excluded in a file export. For example, if you have many internal components that serve as masses or for cabin layout it is unlikely that you want all of these included in an outer mold line for aerodynamics, 3D printing, meshing, etc. Simply place the relevant components into a new Set and export by choosing that Set from the dropdown menu (File > Export… > Normal Set menu).
Component Sets may also be saved as a new OpenVSP model with an important caveat. The component hierarchy in the Model Tree must be preserved for the model to save the Set, meaning that the individual components and ALL relevant ancestor/parent components must also be included in the saved Set.
