Design & engineering

By bringing design constraints and engineering constraints together, we optimize mechanical and physical properties as well as manufacturing processes — from the very first sketch, and according to your priorities.

What we do

Our scope of work.

A modular engagement: we can cover all or part of these areas while staying aligned with the rest of your project.

01

Architecture & sizing

Choice of solution principles, definition of the mechanical architecture and sizing calculations.

02

Design

Aesthetic exploration, visual proposals and definition of the product identity.

03

3D modeling

Full CAD, editable parts and assemblies. Several versions tailored to each need: simulation, manufacturing, animation and rendering…

04

Dimensioned manufacturing drawings

Drafting, functional dimensioning and bills of materials for subcontracting.

05

Material & component selection

Materials chosen to match your objectives, with a review of the relevant post-processing options.

06

Design for manufacturing

Geometries adapted and optimized for your manufacturing process.

When to call us

Rework, strengthen or create your product

“I have a working part, but I need to change how it is manufactured.”

We rethink the geometry of your part so it fits the new process precisely (draft angles, wall thicknesses, tolerances). You secure industrial feasibility while maximizing production yield.

“I have a prototype, but I want to cut its cost or improve its performance.”

Drawing on deep expertise in simulation and materials science, we run a value analysis: lighter material use, more competitive material combinations, or structural optimization.

“I have an idea or a specification, but I don't know how to turn it into a physical product.”

We structure your project from end to end. From the first sketch to the mechanical architecture, we turn your concept into production-grade 3D modeling, ready for prototyping.

“I have a preliminary 3D file, but it cannot be used for manufacturing.”

We bring your CAD up to industrial standards: dimensioned manufacturing drawings, functional tolerances, precise material choices and a complete bill of materials for subcontractors.

“My product or part keeps failing mechanically in use.”

We analyze the loads and the weak areas in order to resize the part, revisit the material choice or change its geometry so it holds up in the field.

“My product works very well, but its look and ergonomics need modernizing.”

We rework the visual identity and the user experience without starting the mechanical architecture from scratch — an appealing result that is easy to handle and never gives up performance.

The Polytechnia advantage

CAD as a pillar, built on solid foundations

Asking the right questions at the right time

We ask the right questions from day one. By anticipating mechanical, material and manufacturing constraints from the very first sketch, we cut down blind spots, delays and cost overruns along the way.

Fewer middlemen, more peace of mind

No more orchestrating the conversation between the designer, the CAD engineer and the manufacturer. We take on the entire technical chain so you can focus on what matters.

Moving past trade-offs with a cross-disciplinary view

Choosing between looks, technical feasibility, features, weight and cost is not inevitable. Our command of every discipline lets us find clever answers where others would settle for a compromise.
