How to convert a 3D model to a 2D plan

I drew out the walls of a room in 2dimensions and used Push Pull to show the height of the walls. Is there any way to get back to a 2D

If you just want to show it as a 2D plan, switch the camera to Parallel Projection and choose the Top view.

Thank you very much DaveR. I was able to achieve what I wanted with your suggested method.
