Drawings & drafts
done right.

Before we wrote a line of code, we drew. Mechanical drafting, blueprints, and 3D modelling for hardware founders, fabricators, and contractors who need it precise, and on time.

How a draft works

A tight loop with clear revisions. You approve at each gate, and every change is logged on the title block.

What software and file formats do you deliver in?

+

We work mainly in AutoCAD, SolidWorks, and Fusion 360, and deliver DWG, STEP, IGES, PDF, and STL, plus the editable source file. Tell us your downstream tool and we'll match it.

I only have a rough sketch. Is that enough to start?

+

Usually, yes. A sketch with a few key measurements, or a photo of an existing part, is plenty to begin. We'll ask questions and confirm the critical dimensions before detailing.

Will you follow our drafting standards?

+

Always. Send your title block and standard (ISO, ANSI, or in-house) and we'll match it exactly so the drawings drop straight into your workflow.

Is my design kept confidential?

+

Yes. We sign an NDA before you share anything sensitive, and your files and IP remain entirely yours. We never reuse client designs.
