You can load a Design file directly from the command line with OpenVSP by executing “
vsp.exe -des <desfile> <filename.vsp3>” where
<desfile> is the name of the Design file and
<filename.vsp3> is the model with the corresponding parameter IDs.
Design files are NOT model agnostic. The parameter IDs for a particular model are saved in the file and will not work with similar parameters on a different model if the IDs are different.
