openvsp.AutoGroupVSPAEROControlSurfaces()[source]¶

Creates the initial default grouping for the control surfaces. The initial grouping collects all surface copies of the sub-surface into a single group. For example if a wing is defined with an aileron and that wing is symmetrical about the xz plane there will be a surface copy of the master wing surface as well as a copy of the sub-surface. The two sub-surfaces may get deflected differently during analysis routines and can be identified uniquely by their full name.
