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!
Small shop in southwestern Ontario, self-built plasma table. No budget for the big software names so I used SheetCAM for my table from the start. Always open for alternatives, I tried various options that came up on plasma cutting and CNC…

Plasma table
JETCAD3 is in my opinion so far the best All in one CAD/CAM solution i have encountered, we have machines running it in the field and its great, i am sure we will produce many many more, Love the software and the support!

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. Router sheet CAM is available on Drafting + Full CAM—contour, bore, drill, chamfer, pocket, and engrave on a nesting-first sheet workflow. Mill is available on the same tier—setup-based 3-axis milling driven straight from the solid model. The lathe workspace is on the roadmap. 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.
JetCad3 aims to bring the depth of expensive CAD/CAM software within reach of small shops and serious garage builders—without the enterprise tax.

A Pre-Paid License buys one to three years of JetCad3 outright, on one computer. Pay for it once, up front, and the longer the term the less each year costs. Nothing renews, nothing is billed again, and there is nothing to cancel.
Savings are measured against paying month to month for the same span. You enter the machine code from the app at checkout — it is on the Offline Key sign-in tab, and in the profile menu once you are signed in.
Not a fan of subscriptions? Neither are we. The JetCad3 Lifetime Unlimited License is a one-time purchase: a hardware key that unlocks the entire suite for good. No monthly bill, no expiration — just plug it in and own it.
The hardware is the license — there's no cloud backup or replacement program for a lost, stolen, or destroyed key. Keep it safe.
A free jetcad.io account is the Free/Hobby tier — the full feature set, metered at 1 hr/day and 5 hr/week of active use (2× on evenings & weekends). No account?

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.
