Built for Builders

What is CADdition?

CADdition is a parametric drawing platform. We design and maintain a growing catalogue of products including gates, fences, frames, and more. Configure any product to your exact dimensions and CADdition produces professional engineering drawing packs with orthographic views, dimension lines, cut lists, and bills of materials.

No CAD software. No steep learning curve. Pick a product, enter your measurements, preview the result in 3D, and download an A4 PDF ready for the workshop floor.

Who is it for?

Fabricators, builders, hobbyists, and manufacturers. Anyone who needs accurate drawings without the overhead of full CAD software. Browse the catalogue, enter your dimensions, and download a drawing pack you can take straight to the workshop.

How it Works

Every product in the catalogue is a parametric model: a set of rules that compute geometry from your inputs. We define which dimensions you can change and what constraints apply. Under the hood, CadQuery validates your inputs, computes the 3D geometry, and projects it into orthographic views with automatically placed dimension lines.

The result is a multi-page A4 drawing pack: front, side, top, and isometric views with every dimension needed to build the thing.

Need Something Custom?

If you can't find what you need in the catalogue, get in touch. We design custom parametric models for paid clients, whether it's a one-off product or a full range of configurable items. Contact us to discuss your requirements.
