This feature lets you not only copy one room and paste the same one into your project, but do it with multiple rooms! It's a great tool, if your project has multiple rooms of the same shape or measurements.
So, how can you select 2 or more rooms and add them to your project? Easy!
Choose the first room you'd like to copy;
