What Datum does

Views from your model. Create plans, elevations and sections with a 3-click section tool. Each View gets its own camera, drawing scale (1:10, 1:50, 1:100…), colour and clipping.
2D annotation planes. Every View carries a Foreground and Background plane for dimensions, symbols, tags and linework that track the section when it moves.
The Navigator. All Views and Drawings in the file, organised into groups — open, duplicate, rename, recolour and manage them from one panel.
Sheets & title blocks. One scene per drawing. Import Views onto sheets at their true paper size, auto-numbered, with editable title block fields.
Real exports. Views and whole drawings export to SVG, PDF, DXF — and DWG when the ODA converter is installed.
