Dimensions And Lines brings a CAD-like dimensioning workflow into Blender. It creates technical drawings, dimensions, and blueprint-style layouts directly in the 3D viewport, and keeps dimensions and lines as real scene geometry that remains fully renderable.
Length dimensions can be created in the viewport, with realtime dimensioning that adds snapping and offset control. For output, the add-on can set up an orthographic camera and calculate render resolution from sheet size and DPI, fitting the orthographic scale to a chosen paper format and drawing scale. Paper presets cover ISO and US sizes from A5 to A0, along with Letter, Legal, Ledger, ARCH A to E, and ANSI A to E.
Dimensions And Lines is licensed under GPL-3.0-or-later. This entry is a free, legacy 1.1.0 build offered for basic use; a newer, more developed version is available from the developer's page.
