Working in 2D and 3D Mode Simultaneously
This short video of about one and a half minutes shows how to work in 2D and 3D mode simultaneously in Plan7Architect. It covers switching between the 2D floor plan view and the 3D view and seeing changes in real time.
Working in 2D and 3D at the same time, sometimes described as a live 3D preview or real-time 3D visualization, makes it easier to understand how a floor plan will look as a finished house.
