Add interior elements

After adding the exterior building elements, focus on interior elements as such stairs and rooms. Attend to components which include items that may be delivered onsite, such as toilets, furniture, and lighting.

Create a switchback stair

Create straight stair runs and use automatic landings to connect and balance each run.

Place rooms

Create rooms based on room-bounding elements such as walls, floors, and ceilings. Add room separation lines where needed.

Place components 

Enhance the design by placing components such as furniture, specialty equipment, and site objects.
