Install Curva

Curva is free. Each release comes as a Windows installer, a macOS disk image and a Linux AppImage, all on the Releases page.

Get the latest release

What you need

• Windows 10 or 11, 64-bit.
• macOS on Apple silicon (M1 or later).
• Linux on a 64-bit PC, with a distribution from 2022 or later (Curva is built on Ubuntu 22.04).
• Graphics: anything from a 2020-era laptop with Intel integrated graphics upwards. A dedicated graphics card helps with large models.

Install

Windows

1. Download the file ending in -setup.exe from the Releases page.

2. Open it. The installer is for your user only, so it doesn’t need administrator rights.

   If Windows SmartScreen says it protected your PC, choose More info, then Run anyway. Curva isn’t signed with a paid certificate yet, so Windows doesn’t recognise it.

3. Curva opens when the installer finishes, and it’s in the Start menu from then on.

To uninstall, go to Settings → Apps → Installed apps, find Curva and choose Uninstall.

macOS

1. Download the file ending in -macos-arm64.dmg from the Releases page.

2. Open it and drag Curva into Applications.

3. The first time, macOS may say Curva can’t be opened because Apple can’t check it. Open System Settings → Privacy & Security, scroll down and choose Open Anyway next to Curva. You only do this once.

Curva isn’t notarised by Apple yet, which is why macOS asks. To uninstall, drag Curva from Applications to the Bin.

Linux

1. Download the file ending in -linux-x86_64.AppImage from the Releases page.

2. Make it runnable: right-click it, open Properties → Permissions and tick Allow executing file as program. Or, in a terminal:

   chmod +x curva-*-linux-x86_64.AppImage

3. Double-click it to open Curva.

An AppImage is the whole program in one file: keep it wherever you like, and delete it to uninstall.

Updates

When Curva opens, it checks GitHub for a newer version in the background. If there is one, the first line of the command bar says so: click it to update. Curva downloads the new version, checks it isn’t damaged, installs it and opens again with your model.

• Windows: Curva offers to save your model, closes, installs the update and reopens.
• Linux: Curva replaces its AppImage with the new one and reopens.
• macOS: Curva opens the new disk image for you to drag to Applications, then opens the new copy.

After an update, the command bar links to what’s new in that version.

Note

To stop Curva checking for updates, turn off Check for updates on opening in Settings → General. You can always download a new version from the Releases page yourself.
