Start from the drawings you already maintain
Most German plants and warehouses have an up-to-date layout drawing somewhere — usually a DWG kept by facility management or plant engineering, plus PDF plan sets for each building. Spatial Map imports both. A DWG (AutoCAD R2004 to R2018) is placed at true size because it is drawn in real-world units; you confirm millimetres, centimetres or metres and choose the layers to show. A PDF sheet is matched to its paper size and you pick the drawing scale, such as 1:100, or enter a known width in metres. DXF is not read directly — save it as DWG or plot it to PDF. The details are in the CAD and PDF import docs.
The imported plan is a picture at the right scale. On top of it you trace what matters operationally: halls and rooms, racks with bin locations, walls, doors, stairs, lifts and aisles. For the general workflow see indoor mapping software.
