What we do

Our CAD service relies on professional tools and a results-oriented approach:

3D modelling of parts and assemblies with SolidWorks, CATIA or Creo, in parametric and surface design.
Mechanical simulations to evaluate the strength, durability and performance of designs (static, modal, thermal).
Model optimisation taking into account manufacturing constraints (machining, sheet metal, welded assemblies, 3D printing) and costs.
Technical documentation: dimensioned and toleranced drawings, manufacturing drawings, bills of materials, assembly instructions.
Design change management following feedback from test or production phases; reworking and cleaning up existing models.

Sectors

Transport, aerospace, space, nuclear, energy, process industries, construction and infrastructure: our designers know the standards and documentation requirements of these sectors.

How we work

Scoping: functional specification, interfaces, applicable standards, deliverable formats (native, STEP, PDF).
Design: design reviews at each milestone, interference and clearance checks, material choices validated.
Industrialisation: drawings, manufacturing file, exchanges with your suppliers.
Delivery and follow-up: native and neutral models, documentation, manufacturing feedback taken into account.

Outsourced in our office or through a designer on assignment in your design office.

What we deliver

Native 3D models (SolidWorks, CATIA, Creo) and neutral exports (STEP, IGES)
Dimensioned, toleranced drawings and bills of materials
Mechanical simulation reports
Manufacturing file and assembly instructions
Revision management and change history

Tools and technologies

Frequently asked questions

Mainly SolidWorks, CATIA V5, PTC Creo and AutoCAD. We prefer to work on your licences and methods (templates, naming rules, PDM) so that the delivered models fit directly into your environment.

Yes, for standard sizing checks (linear static, modal, thermal) with the built-in simulation modules. For advanced analyses, we work with your calculation specialists or refer you to a partner.

It is a frequent request: we rebuild parts with a clean, parametric feature tree, so that future modifications are quick and safe.
