Draw each floor or unit as it is - walls, rooms, openings and fittings - on top of the client's DXF, with the same keys you use everywhere in Atrium. The plan lives in the project on Bond, so the web app and the Rhino plugin open the very same drawing.
Click and type lengths; F8 for Ortho, Tab flips the wall to the other side of the line, ↓ locks parallel to the wall under the mouse. Walls join, and moving one side keeps its neighbours' directions.
Click inside a space or pick its walls and press Enter. Rooms are found from the wall faces; divider lines split open spaces. Areas and wall lengths add up in the plan properties.
Doors (single, double, one-and-a-half), windows with sill and head heights, switches and sockets, split AC, radiators, existing wardrobes, baseboards, ceiling lights and vents, ceiling drops, floor drains - they sit on the wall and move with it.
Free walls, columns, stairs and elevators square up to the nearest wall and stick to it; tables, plants, text and measurements complete the drawing.
Lay the client's DXF faintly under the plan and snap to its corners (save DWG as DXF first). Export a layered DXF in millimetres - walls, named rooms, doors, windows and sizes - for contractors.
Each survey belongs to a project and knows its floor, unit and zone, ceiling height and wall, floor and ceiling materials - one plan per floor or unit, by design.

The plan is one document in the project. Draw it on site in the Bond web app - with a 3D view and a Leica DISTO laser meter, or try the AR room scan on a phone (beta) - and refine it in Atrium; or the other way round. Desktop/web parity is a rule: what one can draw, the other can open.
The 3D view, DISTO input and the AR scan are features of the Bond web app.


The goal: every element on the plan is a real Atrium part or assembly, so the plan itself has a bill of materials and a price. Here is what is designed and what comes first.
