Copy Schematic from Blockset to Blockset

I’d like to copy a schematic from a Blockset circuit to another Blockset circuit but unfortunately this does not work as in Standalone. The only way I managed to do this is by exporting it to a Standalone Model and Importing it back. Is there a better way to do this?

You can use drag&drop or clipboard copy between schematic windows that belong to the same editor application both in PLECS Standalone and PLECS Blockset.

I suspect that you have started two instances of MATLAB/Simulink and thus also have two instances of the PLECS schematic editor. Copying between schematic windows of these two editor applications is indeed not possible.
