Product teams developing physical form
Translate requirements, electronics, interfaces, ergonomics, assembly, and manufacturing into testable mechanical design.
Mechanical concepts, enclosures, components, assemblies, tolerances, and design for manufacture
3D design and CAD services
Rokad develops mechanical concepts, enclosures, components, assemblies, and production-ready CAD around functional, electronic, manufacturing, and user requirements.
Designed for / 01
A focused delivery model for the organisations that need it.
Good 3D design resolves function, fit, assembly, material, tolerance, environment, electronics, user interaction, manufacturing, and service together. Rokad creates conceptual and detailed CAD for prototypes, products, enclosures, fixtures, replacement parts, and low-volume production.
Companies requiring enclosures or custom parts
Develop purpose-built housings, mounts, brackets, adapters, fixtures, mechanisms, and assemblies.
Teams improving an existing mechanical design
Address fit, strength, weight, tolerance, assembly, heat, service, cost, manufacturing, and aesthetic constraints.
Challenges / 02
The problems this service is built to solve.
A visually correct model does not function physically
Clearance, tolerance, fasteners, loads, deformation, heat, cable routing, assembly, and material behaviour are missing.
The prototype process cannot become production
Geometry assumes additive manufacturing and ignores moulding, machining, sheet, casting, assembly, finish, and tooling constraints.
Electronics and mechanics evolve separately
Boards, antennas, connectors, sensors, displays, buttons, heat, mounting, and access are not controlled in one interface model.
Capabilities / 03
What Rokad can deliver.
01
Mechanical requirements, references, measurements, interfaces, and feasibility
02
Concept sketches, form studies, packaging, ergonomics, and architecture
03
Parametric CAD, parts, assemblies, mechanisms, enclosures, and fixtures
04
PCB, connector, antenna, display, control, cable, thermal, and mounting integration
05
Tolerance, fastener, snap, seal, vent, strength, material, and assembly design
06
Design for additive, machining, sheet, moulding, casting, and low-volume production
07
Drawings, exploded views, BOM, renders, prototypes, iteration, and manufacturing handoff
Solution components / 04
The system behind the visible product.
Mechanical architecture
Parts, interfaces, load paths, assembly sequence, access, motion, seals, heat, electronics, and manufacturing split.
Detailed geometry
Features, walls, ribs, bosses, fasteners, snaps, clearances, tolerances, fillets, drafts, and surface intent.
Prototype validation
Fit, function, ergonomics, assembly, strength, thermal, interface, appearance, and iteration using physical parts.
Production documentation
CAD, drawings, dimensions, tolerances, materials, finishes, BOM, assembly, revision, and supplier communication.
Use cases / 05
Where this capability creates practical leverage.
Electronic product enclosure
Package PCB, battery, antenna, display, buttons, connectors, thermal, assembly, service, and user interaction.
Functional mechanical component
Develop brackets, adapters, mounts, housings, ducts, guides, fixtures, covers, and replacement parts.
Prototype mechanism
Test motion, linkage, alignment, force, retention, adjustment, wear, assembly, and operating geometry.
Design-for-manufacture revision
Adapt an existing model to the selected material, process, tolerance, tooling, assembly, finish, and production volume.
Architecture and integration / 06
Designed to fit the wider technology environment.
Interface control
Version board, connector, component, mount, envelope, cable, and external interfaces so parallel work remains aligned.
Tolerance by function
Assign clearances and tolerances from fit, movement, sealing, alignment, process capability, and assembly sequence.
Process-aware geometry
Design wall, draft, support, tool access, bend, undercut, machining, shrink, and finish around the intended manufacturing method.
Quality and control / 07
Production requirements are part of the build.
Requirements before geometry
Fit, function, load, environment, power, interfaces, tolerance, material, production, and service constraints guide design decisions.
Evidence through prototypes
High-risk assumptions are tested with measurable prototypes, inspection, iteration, and documented findings before scale.
Production-aware decisions
Component availability, manufacturing method, assembly, testing, certification, repair, and lifecycle are considered early.
Delivery / 08
A controlled path from requirement to operation.
Discover
Clarify the objective, users, systems, constraints, dependencies, risks, and measurable acceptance criteria.
Architect
Define the target design, interfaces, controls, migration or delivery sequence, and operating model.
Deliver and validate
Implement in controlled increments with testing, review, documentation, observability, and stakeholder validation.
Operate and improve
Establish ownership, service controls, measurement, support, and a prioritised improvement backlog.
Typical deliverables
Mechanical requirements, dimensions, interfaces, and feasibility package
Concept, packaging, form, and mechanical architecture options
Parametric part and assembly CAD source files

FAQ
3D design and CAD services
Scope, ownership, assumptions, delivery, security, and long-term operation are clarified before work begins.
01Can Rokad design from a sketch or physical sample?
Can Rokad design from a sketch or physical sample?
Yes. We can work from sketches, requirements, measurements, scans, photographs, reference products, existing CAD, PCBs, and physical samples, subject to available accuracy.
02Can the design be prepared for injection moulding or machining?
Can the design be prepared for injection moulding or machining?
Yes. We adapt geometry, wall, draft, radii, undercuts, parting, tolerances, tool access, material, finish, and assembly to the selected process.
03Do you provide renders as well as CAD?
Do you provide renders as well as CAD?
Yes. Scope can include technical CAD, exploded views, assembly visuals, presentation renders, material studies, and manufacturing drawings.
04Can Rokad print and test the design?
