A Scottish draughting practice, applying AI to its own craft
Brian McCallum Draughting Ltd has been producing drawings for UK contractors, architects and engineers since 2007. DraughtAI is the software arm of that practice — the same draughting standards, encoded as a product.
The practice
Brian McCallum Draughting Ltd is a private limited company registered in Scotland on 7 November 2007 (company number SC333546). The practice operates from Bishopbriggs in Glasgow and has produced architectural, structural and civil drawings for projects across the central belt of Scotland and beyond.
Our principal SIC classification is 71122 — Engineering related scientific and technical consulting activities, recorded with Companies House since incorporation.
The DraughtAI product line
By 2024 it was clear that perhaps half of any draughting day was spent on tasks that should be automated: re-applying title blocks, redrawing sketches into clean DWG, converting drawings between office standards, and chasing missing dimensions before a sheet went out. We started writing tools to handle these tasks for ourselves. DraughtAI is what those tools became.
The product is intentionally narrow: it does not generate human likenesses, it does not produce marketing imagery, it does not write reports. It does technical drawings, and it does them to BS 8888 / ISO 128 / ISO 19650 by default.
