Hello, unfortunately this is not possible. However, the PLECS Blockset Demo Mode allows you to share a model with someone without a PLECS license and they can still open, view, modify, and simulate (just not save changes to) the circuit. See (https://www.plexim.com/support/installation_help/blockset
) for instructions on starting PLECS in Demo Mode. You are also able encrypt and password protect PLECS circuits before sharing them.
So your customers would need to install PLECS, but are not required to have a license, though they are welcome to request fully-functional trial licenses as well at www.plexim.com/trial.
