Start from the drawings the estates office holds
A UK estate rarely has one tidy set of plans. Newer buildings come with DWG files from the architect or the fit-out contractor; older ones may exist only as PDF sheets, and a listed building’s best plan can be a scan. Spatial Map takes all three. A DWG (AutoCAD R2004 to R2018) is placed at true size in metres or millimetres. A PDF sheet is matched to its paper size, such as A1 or A3, and you pick the drawing scale or enter a known width. A PNG or JPG scan is sized to the building’s real dimensions. DXF needs to be saved as DWG or plotted to PDF first.
On top of the plan you draw what visitors and staff need: rooms, halls, doors, walls, stairs, lifts and escalators, on every floor. The general workflow is on our indoor mapping software page; this one is about the buildings UK teams map.
