The problem

The drawings aren't done. The schedule doesn't care.

Most teams don't have a design problem. They have a capacity problem. The work is there; the bandwidth isn't.

Your queue never gets shorter

Every new part, revision, or rush request lands in the same pile. In-house teams do their best, but drawings don't move until someone has time. And time is the one thing you don't have.

Ambiguous drawings cost real money

A dimension open to interpretation doesn't stay theoretical. The shop makes a call. When it's wrong, you re-machine, re-order, and re-schedule. Then you eat the cost and hope the next drawing is clearer.

Your deadline isn't adjustable

Fabricators, customers, and procurement don't care about your CAD queue. Your due date is fixed whether the drawings are ready or not. Every day without files is a day already spent.

30+ Years of Manufacturing-Ready Design Experience

I've been in the shop. I know what the floor needs, and I know the cost of getting it wrong.

I'm Curtis Sipe, Principal Designer at Sipe Design Group. My career spans aerospace engine hardware for Pratt & Whitney and GE, complex automated manufacturing systems, edge-welded metal bellows products, and hundreds of machined-part and tooling drawings across industries.

That depth means I don't just create models. I create models built to be manufactured. Files your shop can open, trust, and run with. No back-and-forth, no interpretation, no surprises.

"Designed right. Built right. The first time."

How it works

Three steps to manufacturing ready files

No long onboarding. No ambiguity. A clear path from concept to shop-floor-ready output.

1

Share your project

Send sketches, photos, measurements, specs, or an existing file. We'll scope it and confirm turnaround within 24 hours.

2

Receive precise CAD files

Fully dimensioned 3D models and production drawings built to your standards, reviewed for manufacturability before delivery.

3

Ship with confidence

Hand files straight to the shop floor. No rework, no redlines, no surprises. Parts match the drawing the first time.

What you get

CAD services built for manufacturers

Project-based support that slots into your workflow, with no retainers, no overhead, and no learning curve.

SolidWorks 3D Modeling

Parts, assemblies, and configurations built with manufacturing intent: parametric, fully defined, and revision-ready from day one.

2D Production Drawings

Fully dimensioned drawing packages with GD&T, tolerances, surface finish, notes, BOM tables, and title blocks, ready for the shop floor.

Tooling & Fixture Design

Weld fixtures, assembly jigs, forming tools, test stands, guards, and production-support hardware, designed for the floor and not just the drawing.

Design for Manufacturing Review

Practical DFM and tolerance analysis that catches problems before they reach the floor, not after the first batch is scrapped.

Reverse Engineering

From sketches, photos, measurements, or existing parts: a complete, production-ready model built without guesswork.

CAD Backlog Relief

Drawing cleanup, revision updates, redlines, BOM updates, and documentation backlogs, cleared quickly so your team can move forward.

Why it matters

The cost of waiting vs. the value of moving

Without a reliable CAD partner

Delays compound. Costs climb.

  • Drawings backlogged: fabrication can't start
  • Ambiguous dimensions cause shop floor errors
  • Rework and re-machining erodes margin
  • Customer delivery dates slip, and trust along with them
  • In-house team buried in revisions, not new work
With Sipe Design Group

Clear files. Confident production.

  • Manufacturing ready files delivered on schedule
  • Fully dimensioned drawings your shop floor trusts
  • DFM review catches problems before first article
  • Backlog cleared: team focuses on new projects
  • Parts match the drawing. Every time.
