REV.01 · MECHANICAL & PRODUCT DESIGN CAD · COOKEVILLE, TN
Most engineering teams lose weeks waiting on drawings. Sipe Design Group turns your concepts into precise 3D models and production-ready drawing packages so your team ships on schedule, without the rework.
The Problem
Engineering teams run lean. When CAD work outpaces capacity drawings stall, revisions drag, and the shop floor gets incomplete information. That gap between a good idea and a finished, accurate drawing package is where projects slip, budgets bleed, and launches miss.
PROBLEM 01
Missing views. Vague tolerances. Incomplete material callouts. A drawing that's "close enough" becomes a machining error, a weld in the wrong place, or a part that doesn't fit. By the time it gets caught, you've already paid for the mistake.
Production-ready means nothing is left to interpretation. Every view, every tolerance, every note clear and correct before it hits the floor.
PROBLEM 02
Senior engineers should be solving hard problems not spending afternoons converting napkin sketches, cleaning up legacy drawings, or grinding through revision cycles.
When your in-house capacity is tied up in CAD work, the things that actually need an expert mind get pushed to the back. That's not an engineering problem. That's a resource problem.
PROBLEM 03
Some of the best products never get built not because the concept was wrong, but because turning an idea into a manufacturable design package requires time, skill, and the right tools that the inventor or small team doesn't have available.
A concept without a drawing is just a sketch. A drawing without manufacturability review is just paper. The gap between those two things is exactly where we work.
Your Guide
I'm Curtis Sipe mechanical design engineer, Gulf War veteran, and the person who will actually do your work. No hand-offs. No junior designers learning on your dime. You send me a sketch, a prototype, or a legacy drawing and I deliver production-ready files built to your standard.
I've spent 30+ years turning mechanical requirements into manufacturable designs for aerospace engine configurations at Pratt & Whitney and GE, for automated manufacturing equipment, and for precision bellows products. I know what the shop floor needs. I know where drawings break down. And I build to avoid both.
The Plan
No complicated onboarding. No project management overhead. Send what you have, and we'll take it from there.
A sketch. A prototype. Legacy drawings. Measurements from an existing part. Whatever you have that's enough to begin. We'll confirm scope and quote upfront, no surprises.
Full SolidWorks 3D models, complete 2D drawing packages, GD&T, tolerances, and BOM documentation built to your drafting standard and reviewed against manufacturability before delivery.
Revision-controlled deliverables in the formats your shop needs. NDAs honored. Direct access to the engineer who did the work every time.
Project-based support for manufacturers, machine shops, fabricators, inventors, and overloaded engineering teams the exact work your team needs, without adding headcount.
Parametric part and assembly models built to your design intent, ready for simulation, rendering, or downstream drawing production.
Fully dimensioned drawing packages with GD&T, tolerances, material callouts, and manufacturing notes built to survive the shop floor.
Welding fixtures, assembly jigs, forming-support tooling, inspection aids designed for function, ease of build, and real-world use.
Drawing revision updates, legacy CAD cleanup, format conversion, and backlog clearing fast turnaround without losing your standards.
Early-stage concept modeling, design-for-manufacturing review, reverse engineering from parts or sketches, and prototype drawing support.
Bills of Materials, manufacturing operation instructions, work instructions, inspection standards, and visual workmanship guides.
Best-Fit Clients
If your drawings need to get done and your team is already at capacity, this is where Sipe Design Group fits.
Ready to Move Forward?
A sketch, a photo of an existing part, a legacy drawing whatever your starting point is, it's enough. Fixed quotes upfront. NDAs honored. Direct access to the engineer doing your work.
