3D CAD Modeling & Product Design
Design for the way the part will actually be made.
Good CAD is more than a digital shape. A useful engineering model needs to reflect how the component will be manufactured, assembled, loaded, modified, and maintained. 3DRM Tech develops 3D CAD models for products, mechanical parts, prototypes, replacement components, tooling, enclosures, and custom hardware.
Projects can begin at almost any stage. Bring us a sketch, a set of dimensions, a technical requirement, a photo, a physical component, scan data, or an existing CAD file that needs refinement. We can develop the geometry and continue directly into 3D printing, CNC machining, or rapid prototyping.
You do not need a finished engineering drawing to start. If you can explain
what the part needs to do and provide the information you have, our team can
help determine the right path from concept to manufacturable CAD.
CAD Design Capabilities
From first concept to production-ready geometry.
Different projects need different levels of CAD support. We can create a new model from scratch, rebuild an existing part, optimize geometry for manufacturing, or modify files you already have.
02
Product Design & Development
Develop housings, components, assemblies, interfaces, and product geometry that can move into physical prototyping.
03
Mechanical CAD Design
Model brackets, mounts, fixtures, enclosures, adapters, mechanisms, machine components, and other functional parts.
04
Reverse Engineering CAD
Recreate existing physical components as editable digital models when original files or technical drawings are unavailable.
05
Design Modification
Update existing CAD to change dimensions, interfaces, mounting points, clearances, features, or manufacturing requirements.
06
Design for Manufacturing
Prepare geometry around the chosen production process so the design is practical to print, machine, prototype, or reproduce.
What Can You Send Us?
Start with whatever information you already have.
The starting point does not need to be perfect. The right inputs depend on the project, but many CAD jobs begin with incomplete information that gets refined through the design process.

CAD Software
Professional design tools for different geometry and workflows.
3DRM Tech's Montreal-based design team works with SOLIDWORKS, Fusion 360, and Rhino. The software is selected around the modeling task, geometry, downstream manufacturing process, and file requirements.
SOLIDWORKS
Mechanical and parametric CAD workflows for engineered components and assemblies.
Fusion 360
Integrated product, mechanical, prototyping, and manufacturing-oriented workflows.
Rhino
Flexible modeling for complex surfaces, freeform geometry, and specialized shapes.
Design for Manufacturing
The manufacturing process should influence the CAD.
A model that looks correct on-screen may still be expensive, difficult, or impossible to manufacture efficiently. Because 3DRM Tech also produces parts, CAD design can be developed with the intended process in mind.
3D Printing
Consider wall thickness, print orientation, supports, overhangs, material behavior, assembly, and process-specific geometry.
CNC Machining
Consider cutter access, internal radii, setups, workholding, material removal, tolerances, and avoidable complexity.
Composites
Plan geometry around molds, layup access, structural direction, transitions, interfaces, and practical fabrication.
Low-Volume Production
Design for repeatability, assembly, production efficiency, revision control, and a consistent manufacturing route.
CAD Design Process
From project requirements to a manufacturable model.
The exact design workflow depends on how developed your project already is, but most CAD jobs move through four stages.
01
Define the Part
Share the concept, dimensions, function, interfaces, references, existing files, or physical component and explain what the finished design needs to accomplish.
02
Build the CAD
We develop the 3D geometry around the supplied information, project requirements, and intended manufacturing approach.
03
Review & Refine
Dimensions, interfaces, shape, manufacturability, fit, and project-specific details can be revised before production.
04
Prototype or Manufacture
Move the completed design directly into 3D printing, CNC machining, rapid prototyping, composites, or another suitable process.
CAD Design Applications
What do we design?

CAD Design FAQ
Common questions about CAD design in Montreal.
What CAD design services does 3DRM Tech provide?
We provide 3D CAD modeling, product-development support, mechanical CAD, reverse-engineering CAD, scan-to-CAD reconstruction, design modifications, and manufacturing-ready models.
Can you create CAD from a sketch or idea?
Yes. Projects can begin with sketches, dimensions, photos, specifications, references, or a written description of what the part needs to do.
Can you reverse engineer an existing physical part?
Yes. Our 3D scanning and CAD design services can work together to rebuild existing components when original design files are unavailable.
Which CAD software do you use?
3DRM Tech's Montreal-based design team works with SOLIDWORKS, Fusion 360, and Rhino depending on the geometry and project workflow.
Can you prepare a model for 3D printing?
Yes. CAD can be created or refined with additive manufacturing in mind, and the finished project can move directly into our 3D printing service.
Can you prepare CAD for CNC machining?
Yes. Geometry can be developed around machining constraints and then evaluated for production through our CNC & metalworking service.
What information should I send for a CAD design quote?
Send any available sketches, photos, dimensions, existing CAD, drawings, scan data, quantity expectations, intended manufacturing process, and a short explanation of the part's function.
Can you modify an existing CAD model?
Yes. Existing models can be updated to change dimensions, interfaces, features, clearances, manufacturing requirements, or other design details.
Do you only provide CAD, or can you manufacture the part too?
3DRM Tech can continue from CAD into 3D printing, rapid prototyping, CNC machining, composites, and low-volume production, depending on the project.
Where is 3DRM Tech located?
3DRM Tech is located at 1640 St Clare Rd, Mount Royal, Quebec H3R 2P1 and serves customers throughout Montreal, Quebec, and Canada.
