Download Treform.
An AI agent panel that lives alongside Rhino. Describe what to build, attach a reference image, and watch the geometry appear in your viewport — powered by your existing Treform account. Works alongside Rhino, Revit, AutoCAD, SketchUp, and Grasshopper.
Treform Desktop requires Rhino 8 SR29 or later — earlier Rhino versions aren't supported.
macOS shows "Treform cannot be opened because Apple cannot check it for malicious software" the first time you double-click — the build isn't notarised yet (Apple Developer signing in progress). One-time workaround:
- Open the
.dmgand drag Treform.app into your Applications folder. - In Finder, find Treform.app and right-click → Open (not double-click).
- A dialog reads "macOS cannot verify the developer…" — click Open on the right.
- That's it. Every subsequent launch is a normal double-click.
On macOS Sequoia (15) and later you'll instead see "'Treform' Not Opened — Apple could not verify 'Treform' is free of malware that may harm your Mac…" with only Move to Trash and Done. There's no Open button in this dialog — use System Settings instead:
- Click Done (do not click Move to Trash).
- Open System Settings → Privacy & Security and scroll down to the Security section.
- You'll see "'Treform' was blocked to protect your Mac." — click Open Anyway.
- Confirm with Touch ID or your password, then click Open Anyway once more in the prompt.
- Treform launches. Every later launch is a normal double-click.
Prefer the terminal? Run xattr -dr com.apple.quarantine /Applications/Treform.app once, then open Treform normally.
Once we're enrolled in the Apple Developer Program, signed + notarised builds replace this — double-clicking will just work, no right-click dance.
Windows shows a "Windows protected your PC" SmartScreen warning the first time you run the installer — we haven't bought an EV code-signing certificate yet, so SmartScreen flags the unrecognised publisher. One-time workaround:
- Double-click the downloaded
Treform-windows-x64-setup.exe. - When SmartScreen pops up, click the small "More info" link.
- A "Run anyway" button appears at the bottom of the dialog — click it.
- The installer launches normally. Subsequent launches don't show the warning.
SmartScreen reputation also builds up with installs — after enough users run it, Windows stops warning automatically. EV cert is the permanent fix.
- Sign in with your Treform account.
- Click Connect in the header. Treform installs the Rhino bridge automatically and starts it for you — no
PackageManageror_mcpstartcommands to type. - (First Connect only, macOS) macOS asks for Accessibility permission so Treform can drive Rhino's command line. Click Allow in System Settings, then Connect again.
Both macOS Gatekeeper and Windows SmartScreen flag any binary that isn't signed with a paid OS-vendor certificate. We're getting those (Apple Developer + Authenticode), but until then you can verify the binary independently:
- Source: github.com/zilinjing-bot/treform — the full code that produced this binary.
- Builds: GitHub Actions desktop-build runs — public CI history, including the run that produced your download.
- Verify on macOS:
shasum -a 256 ~/Downloads/Treform-mac-arm64.dmg— compare against the SHA-256 shown on the matching GitHub Actions run's artifact page.
Prefer no install? The web app (beta) works in any browser — open app.treform.ai. A Linux build is on the roadmap.
