Professional 2D/3D CAD and CAM for machinists, plasma and laser operators, and CNC makers. Constraints that make sense and don't blow your sketch up. Offline/air-gapped use fully supported!
JetCad3's sketcher does what it says on the tin. Draw lines, arcs, splines. Trim, extend, offset, mirror. Place text with any installed font — output as exact spline geometry, not rasterized glyphs. Mark geometry as construction and it stays out of your solid. Use window or crossing selection exactly like every other CAD tool you've ever touched. No phantom conflicts. No yellow sketches for no reason.
JetCad3 loads every shape as a portable .jshape file—JavaScript modules that declare parameters and emit 2D geometry through a small, documented API. Bundled mechanical, fabrication, and tool profiles ship with JetCad3, and you can add unlimited custom definitions: author in the built-in editor, refresh the catalog, and share the same file with your team or customers. Shapes run in a sandbox with no filesystem, network, or Node require access, so only the geometry you intend reaches your sketches, Design art, Laser jobs, and Plasma sheets.
On Windows, JetCad3 can be a single self-contained executable via the portable release — no installer, no admin rights, no IT ticket. Copy it to a USB drive, plug in at any machine in the shop, and you're making chips. Installer also supported if that's your preference. Because your time is better spent cutting metal than configuring software.
JetCad3's Plasma workspace is available now. Full toolpath generation for plasma tables with arc-preserved G-code, auto-nesting, kerf compensation, lead-in/out, pierce delay, and cut simulation. Open SheetCAM `.job` files directly—keep your nested layouts or re-nest in JetCad3. Laser is available in the same tier—layer-driven cut and engrave operations, nesting, and controller-ready output including Ruida workflows. Already on SheetCAM or Fusion 360? Import your jobs and posts—JetCad3's AI converter rewrites SheetCAM and Fusion post processors to native format in seconds. Router, mill, and lathe workspaces are on the roadmap.
JetCad3 aims to bring the depth of expensive CAD/CAM software within reach of small shops and serious garage builders—without the enterprise tax.
Download JetCad3 with no account, no login, and no credit card. The Design workspace is fully unlocked for hobby use—vector drawing, imports, image trace, layer-based layout, and typography without caps. Drafting and CAM features remain available on the same install with sensible free limits enforced locally; upgrade when you need full parametric CAD or posting without those caps.
Free-tier limits apply to Drafting and CAM in the installed app—not to the Design workspace. For full paid-tier CAD/CAM without those caps, start a paid plan's 30-day trial when you're ready.
Download JetCad3Full-featured 2D/3D parametric CAD. Everything you need to design and export parts.
Everything in Drafting, plus plasma and laser sheet CAM. Already on SheetCAM or Fusion 360? AI converts your existing post processors automatically.
Everything in Plasma & Laser, plus 2.5D router, 3-axis mill, and lathe/turning toolpaths.
The Design workspace is unlimited without an account; other workspaces use sensible free limits enforced in the installed app (see the Free card). Paid plans include a 30-day free trial; credit card required to activate the trial. License via desktop sign-in online, or an offline license key for air-gapped installs. Your part files are standard formats saved locally; they're yours regardless of subscription status.
Pick your platform. Download JetCad3 and try it free with no account, no login, and no credit card. When you are not signed in, use is limited: Drafting—one component and up to five sketches total; Plasma—up to 500 lines of posted G-code output.
