What is the last step in the process of swapping a floor plan?

The last step in the process of swapping a floor plan is to click the checkmark. This action signifies that you have made your selection and are ready to finalize the changes. In the context of Cvent's diagramming tool, the checkmark acts as a confirmation button that ensures your choice is registered in the system. Until this action is taken, the floor plan swap is not finalized, which is why it is considered the concluding step in the process.

Selecting the diagram is an important earlier step, as is confirming your choice, but the actual finalization hinges on clicking the checkmark to complete the operation. Returning to the main menu would typically occur after the process is fully completed, not as part of the last steps in swapping the floor plan. Therefore, clicking the checkmark is crucial as it closes the transaction and updates the system with your selected changes.
