I am trying to run an Optistruct optimization with several active design constraints. I would like to see the effect of the outcome by turning certain constraints on or off. I have tried turning off the visibility of the constraints in the model tree and exporting only "visible." components to Optistruct but it doesnt work. I know that in the control deck, the DCONADD is the card that controls the constraint activations, however I dont know how to access this from the Hypermesh GUI interface.
