Is it a Virus?
NO - Safe
Must be in C:\Program Files\Autodesk\SketchBook\PlugIns\SketchBookPlugin\sketchbook-plugin.exe
Can I Disable?
YES
Disabling may stop plugin features or plugin loading in SketchBook; UI may rely on this host to enable tools from plugins

Removal disables plugin features; reopen SketchBook to confirm
If you uninstall or delete the plugin folder, plugin features in SketchBook may disappear or cause errors until reinstalled
What is sketchbook-plugin.exe?
sketchbook-plugin.exe is the executable that loads and manages third-party plugins inside Autodesk SketchBook. It runs as a dedicated host process to load plugin modules from the PlugIns folder, and communicates with the main process. It helps keep the editor responsive while enabling extended features.
The plugin host starts with SketchBook, loads plugin modules from the PlugIns folder, and communicates with the main process via IPC. This separation minimizes crashes and improves stability when using external tools.
Quick Fact: SketchBook uses a plugin-host model so third-party tools can extend drawing capabilities without compromising the core app.
Types of SketchBook Plugin Processes
- SketchBook Host Process: Main UI and plugin manager shell
- Plugin Host Process: Loads each plugin in a sandboxed environment
- Canvas Rendering: Renders drawing canvas and preview layers
- Background Services: Handles plugin-related background tasks and communications
- Resource Loader: Loads plugin resources (images, presets)
Is sketchbook-plugin.exe Safe?
Yes, sketchbook-plugin.exe is safe when it's the legitimate Autodesk plugin host and located under the official SketchBook PlugIns folder.
Is sketchbook-plugin.exe a Virus or Malware?
The real sketchbook-plugin.exe is NOT a virus. Malware may masquerade with similar names, so verify location and signature.
How to Tell if sketchbook-plugin.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\Autodesk\SketchBook\PlugIns\SketchBookPlugin\sketchbook-plugin.exe or C:\Program Files (x86)\Autodesk\SketchBook\PlugIns\SketchBookPlugin\sketchbook-plugin.exe. Any other location is suspicious.
- Digital Signature:: Right-click the file in File Explorer -> Properties -> Digital Signatures. Should show "Autodesk, Inc." as the signer.
- Resource Usage:: Normal usage is 2-12% CPU and 40-150 MB memory. Consistently higher usage when SketchBook is idle is suspicious.
- Behavior:: Should only run when SketchBook loads plugins or you open a plugin-enabled project. Persistent background activity when SketchBook is closed is a red flag.
Red Flags: If sketchbook-plugin.exe is found outside the official PlugIns folder (e.g., Temp or AppData), runs without SketchBook open, lacks a valid signature, or uses unusual CPU constantly, scan with security software. Look for files named like "sketchbook-plugin.exe" from untrusted sources.
Why Is sketchbook-plugin.exe Running on My PC?
sketchbook-plugin.exe runs when SketchBook initializes its plugin system, loads plugin modules, or when you enable plugin features in your workspace.
Reasons it's running:
- Active Plugin Use: You're actively using plugins in SketchBook; each plugin loads in its own host process to supply tools or effects.
- Background Plugin Loading: SketchBook may preload selected plugins to reduce latency when you access tools.
- Startup Launch: SketchBook loads the plugin host on startup so plugin features are available immediately.
- Auto-Update or Sync: Plugins may fetch updates or sync preferences with Autodesk servers in the background.
- Plugin Manager: The Plugin Manager keeps track of installed plugins and may instantiate host processes for each enabled item.
Can I Disable or Remove sketchbook-plugin.exe?
Yes, you can disable plugin loading for SketchBook. This reduces plugin features but preserves core drawing capabilities. You can remove the plugin from the PlugIns folder if needed.
How to Stop sketchbook-plugin.exe
- Close SketchBook: Exit the application to stop the plugin host from running.
- Disable Plugins: In SketchBook, go to Preferences > Plugins and toggle off plugins you don't want.
- Remove Plugin Folder: Delete the folder <code>C:\Program Files\Autodesk\SketchBook\PlugIns\SketchBookPlugin</code> or rename it to disable.
- Reopen SketchBook: Launch SketchBook to verify the plugin host does not load.
- Optional Cleanup: If you want to prevent reinstallation, disable any startup tasks or remove related entries from the Plugin Manager.
