Established in 2019 and operating from Hampshire, the business is built on more than 25 years of hands-on industry experience supporting architects, engineers, steel fabricators and contractors across a wide range of project types.

3DSDS exists to bridge the gap between design intent and fabrication reality.

The company delivers both 2D and 3D structural steel detailing using fully licensed, industry-standard software. This includes the production of fabrication drawings, general arrangement drawings, connection details, bills of materials and CNC-ready data. Work is carried out to recognised UK and international standards, with close attention paid to tolerances, fixing methods and site practicality. From primary steel frames and secondary steelwork to staircases, balustrades and bespoke architectural metalwork, 3DSDS supports projects of varying scale and complexity.

Alongside detailing services, 3DSDS also provides CAD training and technical support. These services are designed for individuals and businesses looking to improve their use of AutoCAD and steel detailing software, whether they are new to CAD or experienced users seeking to work more efficiently.
