Is there a way to prevent this

[cbanchik]

We have 1 Structure Revit Suite, 1 Arch Revit Suite, and 1 Building Design Suite.  If the guy with the Design Suite opens AutoCAD, than the two other guys open AutoCAD and starts working.  The problem is if the first guy needs to get into Inventor it won't let him because they aren't grabbing the right licenses.  Is there any way to prevent this?

There is a know cascading licensing issue that occurs with the Building Design Suites and another Autodesk products.

To resolve, please create a technical support request from within the Subscription Center, providing all relevant licensing (serial numbers of the products listed in your original message) and server information (server name and mac address), making sure that you have "Cascading License" somewhere in the case subject line. Once received we will provide you with a new license file that is setup to pull seats in the correct order.

Please feel free to let me know if you have any additional questions or inquiries and I'd be more than happy to accommodate.
