Where AI fits in this workflow

AI is useful before the detailed release workflow begins: it can translate a brief for a housing, lid, mounts, vents, and cutouts into a parametric first pass. Prompt2CAD helps that first pass happen in minutes, then exports STEP so the enclosure can be validated against the PCB and completed in your mechanical CAD system.

The 10 tools in detail

Honest pros, cons, and where each one fits in a real workflow.

01Prompt2CADAI-native

Best for: Conversational enclosure concepts: housings, lids, mounting posts, vents, and snap-fit layouts

Pricing: New signups and free trials are temporarily paused; CAD-file exports unlock after a paid top-up

Platforms: Web

Prompt2CAD helps turn an enclosure idea into editable geometry you can inspect and revise. Describe the board, connectors, mounting method, lid, vents, and constraints; compare housing variations through conversation; then export STEP to continue reviewing and refining the design in your CAD tools.

✓ Pros

  • Creates parametric enclosure geometry from a natural-language brief
  • Conversational changes to wall thicknesses, clearances, bosses, and cutouts
  • Exports STEP for further CAD review and STL for slicer preparation

- Cons

  • Not a PCB-layout or production-release environment
  • Generated geometry needs independent checks for board fit, tolerances, thermal needs, and process suitability

02Autodesk Fusion

Best for: End-to-end enclosure design, prototyping, and manufacturing

Pricing: Free for personal use, paid plans from $680/year

Platforms: Mac, Windows, Web

Fusion is the practical all-rounder for a hardware team that needs enclosure CAD to continue into prototypes, manufacturing drawings, and CNC or fabrication preparation.

✓ Pros

  • Strong parametric solids, drawings, and integrated CAM
  • Electronics workspace connects PCB and enclosure workflows
  • Large learning community

- Cons

  • Complex feature set for quick concept work
  • Advanced workflows take time to learn

03SOLIDWORKS

Best for: Professional product enclosures with controlled assemblies and drawings

Pricing: Makers from $48/year, commercial plans from $2,820/year

Platforms: Windows, Web

SOLIDWORKS is a fit for enclosure programs that require release processes, detailed drawings, revision control, and established supplier workflows.

✓ Pros

  • Mature part, assembly, drawing, and simulation ecosystem
  • Excellent supplier and manufacturing handoff
  • Widely used in professional hardware development

- Cons

  • Commercial plans may exceed the needs or budget of an early concept workflow
  • Windows-centric and more than early concepts need

04Onshape

Best for: Collaborative enclosure development in the browser

Pricing: Free public plan; Standard from $1,500/year, Professional from $2,500/year

Platforms: Web, iOS, Android

Onshape is a good fit when electrical, mechanical, and industrial-design collaborators need to review the same enclosure model without maintaining local file copies.

✓ Pros

  • Live multi-user collaboration and built-in version history
  • No desktop installation or file passing
  • Strong part and assembly modeling

- Cons

  • Private work needs a paid plan
  • Always-online workflow

05FreeCAD

Best for: Open-source parametric enclosure design

Pricing: Free, open-source

Platforms: Windows, Mac, Linux

FreeCAD is a credible no-cost choice for printable cases, brackets, and electronics housings when an open-source workflow matters more than commercial polish.

✓ Pros

  • No license cost
  • Capable Part Design workflow
  • Python scripting and active community

- Cons

  • Less polished interface
  • Complex workflows require more setup

06Shapr3D

Best for: Fast manual enclosure modeling on iPad

Pricing: Free Basic plan, paid plans from $299/year

Platforms: iPad, Mac, Windows

Shapr3D is well suited to designers who want to shape and refine an enclosure manually on an iPad, especially after importing an initial STEP concept.

✓ Pros

  • Excellent direct-modeling workflow
  • Apple Pencil support
  • Approachable for CAD newcomers

- Cons

  • Less complete for formal drawings and complex assemblies
  • Advanced export needs a paid plan

07Altium Designer

Best for: PCB-led electro-mechanical workflows

Pricing: Quote-based

Platforms: Windows

Altium is relevant when the PCB is the source of truth. Pair it with mechanical CAD for the housing, and use ECAD-MCAD exchange to keep connector and board constraints aligned.

✓ Pros

  • Strong PCB design and MCAD collaboration
  • Board shape, components, and connector constraints stay central
  • Professional electronics ecosystem

- Cons

  • Not a general mechanical modeler
  • Cost and learning curve suit professional electronics teams

08Solid Edge

Best for: Synchronous CAD and Siemens-based product development

Pricing: Community Edition free, commercial plans quote-based

Platforms: Windows

Solid Edge is a capable alternative for teams that value synchronous technology or already work in a Siemens-oriented engineering stack.

✓ Pros

  • Combines direct and parametric modeling
  • Strong mechanical design and drafting tools
  • Free community edition for eligible users

  • Smaller learning ecosystem than Fusion or SOLIDWORKS
  • Windows-only

09Rhino 3D

Best for: Ergonomic and consumer-product enclosure surfaces

Rhino shines when the enclosure's exterior form is the hard problem: handheld products, ergonomic grips, and visible consumer hardware.

✓ Pros

  • Exceptional NURBS surfacing
  • Good for organic external forms
  • Grasshopper enables procedural variants

- Cons

  • Less natural for engineering assemblies
  • Needs a companion workflow for release documentation

10KiCad

Best for: Free PCB layout before mechanical handoff

KiCad does not replace enclosure software, but it gives the mechanical designer an accurate PCB, connector positions, and a STEP reference to build around.

✓ Pros

  • Full PCB design without license cost
  • 3D board viewer and STEP export
  • Large maker and open-hardware community

- Cons

  • Not enclosure CAD
  • Mechanical design requires an external CAD tool

Frequently asked questions

What is the best software for electronics enclosure design?

Fusion is the strongest all-round option for many hardware teams. SOLIDWORKS is better suited to formal production engineering, Onshape excels at collaboration, and FreeCAD is the capable open-source option. Prompt2CAD is useful upstream when you need to turn an enclosure idea into editable geometry quickly.

Can AI design a 3D-printable electronics enclosure?

AI can accelerate the initial geometry: housing walls, lids, mounting bosses, vents, connector cutouts, and snap-fit concepts. It cannot replace board validation, tolerance testing, thermal analysis, or print-and-fit prototypes. Prompt2CAD exports STEP and STL so those checks can continue in the tools and process you already use.

How do I design an enclosure around a PCB?

Start with the accurate board outline, component heights, connector locations, mounting holes, and clearance requirements. Importing a PCB STEP model into mechanical CAD is common. Then add wall thickness, fastening strategy, ventilation, access cutouts, and manufacturing draft or tolerances for the selected process.

What wall thickness should a 3D-printed enclosure use?

It depends on material, printer, size, load, and fastening method. FDM enclosures often begin around 1.6-2.4 mm, then are tested and adjusted. Treat generic values as a prototype starting point rather than a production specification.

Can Prompt2CAD replace an ECAD tool?

No. Prompt2CAD creates mechanical CAD geometry, not PCB schematics or layouts. Use KiCad, Altium, or another ECAD tool for the board and use Prompt2CAD to accelerate the mechanical enclosure concept around its requirements.
