Hi,
Is there any way to limit the number of times Rhino can be opened? You cannot open more than one Rhino on the same computer at the same time.
Here is one idea - there are many ways to allow only 1 instance in a C# plugin - you can then trigger Rhino to close. It won’t prevent it loading though.
I already do this; I close the Rhino after executing the program.
But I really needed to limit Rhino’s opening to a single instance.
Do you use any kind of startup.exe of some kind? That is what we do to manage multiple instances. We allow it but coordinate things appropriately for our plugin(s).
I think it would be heavy handed for a plugin to prevent a user from launching additional Rhino instances. That doesn’t sound like something a plugin should be doing.
