You do not need to arrive with a finished CAD model. Stage 13 can work from an idea, functional requirements, dimensions, sketches, technical drawings, reference images, existing CAD or information about an interface or assembly.
The goal is a clearly scoped CAD design or 3D model for a custom technical component. CAD work can be commissioned independently of 3D printing. If a physical part is useful later, printing or prototyping can be considered as a separate downstream step.
Start with the information you have
Begin with what is available: a concept, a short description of the function, known dimensions, a sketch, drawing, reference image, current CAD file or assembly information. This is enough to start a technical discussion and define what the project needs.
Critical dimensions, mating conditions, interfaces and functional requirements must be defined or confirmed during the project. Images can help explain the part, but they are not a substitute for the dimensions that control fit or function.
What can be designed or adapted
The project may involve:
- designing a new custom technical component;
- developing a mount, carrier, base, bracket or interface component;
- modifying an existing CAD model;
- adapting existing geometry around a customer-defined interface or assembly; or
- considering the design in relation to an intended manufacturing route, when that route is known.
The CAD scope is defined around the part, its interfaces and its requirements. If the actual need is to reconstruct a broken, unavailable or discontinued part, see Custom Replacement Parts.
From requirements to an agreed CAD design
- Clarify the component’s function, interfaces, critical dimensions, use conditions, available references and desired changes or output.
- Develop or adapt the CAD geometry and review it against the requirements agreed for the project.
- The CAD deliverable and file format are agreed as part of the project scope. If useful, continue separately to a prototype or fit-check stage, or review an appropriate manufacturing route.
The intended manufacturing route can be discussed when it is known, but CAD work does not depend on placing a 3D printing order with Stage 13. If 3D printing becomes the selected next step, see Industrial 3D Printing.

See the Engineering Portfolio for additional engineering design examples.
Discuss the part and send what you have
When you contact Stage 13, include whatever is available:
- the part’s intended function and use;
- known dimensions and critical interfaces;
- sketches, technical drawings, reference images or existing CAD;
- the changes needed, if adapting existing geometry; and
- the intended manufacturing or prototype route, if known.
An idea, sketch or set of requirements is a suitable starting point for a discussion. If you already have a CAD file or drawing and enough information for technical review, you can use the secondary file-review route.
