Generally for a single story house you need to create 3 Storys; 0.Sea Level/ Datum, 1.Ground Floor & 2.Roof. 0.Sea Level/ Datum is where you construct your 3D mesh and draw your site info. 1.Ground Floor is where you Model your ground floor; walls, slab, windows/ doors, furniture etc. This is also where you ‘Draw’
You can have drawings autoflow onto new layouts by setting the ‘Create new when Layout is Full’ option in your Master settings under Auto Arrange Setup. NOTE: This autoflow method only works in the initial placement of drawings. It’s great for placing large numbers of Details, or Interior Room Elevations etc.
