The Problem

Every Drawing You Wait For Is Money Left On The Table.

You can weld it. You can measure it. But you still need someone else to draw it before you can start. A three-day drawing delay on a $4,000 gate job costs you $800 in idle time — and that's before counting the quotes you never sent because turnaround was too slow.

The Waiting Game

You take site measurements Monday. Email them to your draftsperson. Wait two days. Get drawings Thursday. Find a wrong dimension. Email back. Wait again. The material sits. The client chases you.

The Mistake Tax

A transposed number. A missing dimension. You cut the steel, tack it up, and the frame doesn't fit the opening. That's your time, your material, and your margin — gone. Hand-drawn numbers are the most expensive mistakes in the shop.

The Quotes You Never Sent

A job lands in your inbox. You know you can do it. But your draftsperson is backed up and turnaround is three days — and the client wants drawings by tomorrow. You pass. That's not a delay. That's a job someone else won.

Before You Decide

Yeah, But…

The questions every fabricator has... and the straight answers.

Every drawing is computed from a full 3D solid model using CadQuery — the same OCCT geometry kernel used in FreeCAD and professional CAD tools. Dimensions are accurate to sub-millimetre precision. Four orthographic views are projected from the model, not hand-drawn or stretched. The output is a proper engineering drawing pack — the same quality you'd get from a draftsperson, generated in seconds.

Sub-millimetre accuracy from a professional geometry engine

That's exactly why this exists. Enter your actual site dimensions — opening width, post height, tube sizes — and the engine rebuilds everything from scratch: the 3D model, dimension lines, cut list, and BOM. Nothing is stretched or scaled. Every measurement is recomputed for your specific job.

Every dimension recomputed from your inputs — not a template

You don't need to. There's no software to install, no files to manage, no CAD commands to learn. You pick a product, type in your measurements, and hit generate. If you can measure an opening and fill in a form, you can use CADdition. The whole thing takes sixty seconds from start to finish.

No software, no CAD skills, no learning curve

Change the number, hit generate, and you've got a new drawing pack in sixty seconds. No emailing a drafter. No waiting two days. No revision fee. The old way punishes you for changes. This way, changes cost you nothing.

Unlimited free regenerations — change any dimension, any time

There isn't one. No credit card. No account. No trial that expires. You generate a drawing pack, download the PDF, and it's yours — print it, email it, pin it to the workshop wall. The output is full-quality, production-ready. We're building the tool we wish existed when we needed fabrication drawings fast.
