About Dimensions And Lines
Dimensions And Lines introduces a CAD‑like workflow to Blender, allowing users to create length dimensions, snapping, and offset control directly in the 3D viewport. All dimensions and lines are kept as actual scene geometry, so they render with the rest of the model. The add‑on can automatically set up an orthographic camera, compute render resolution from sheet size and DPI, and match scale to a selected paper format. Paper size presets include ISO A5‑A0 and US formats such as Letter, Legal, Ledger, ARCH A‑E, and ANSI A‑E. Licensed under GPL‑3.0‑or‑later, this free legacy 1.1.0 build was last updated in March 2025; a newer version is available from the developer’s page.
