To control the brush radius for push and delete tools open the settings menu then increase or decrease the “Brush Radius”
To change the frequency of points in “SHIFT” (Turbo) Mode increase or decrease the “Turbo Place Point Distance (Pixels)” setting
For fine detail annotations or high-resolution images, the loupe zoom multiplier in the top left’s zoom can be controlled in settings
Starting a polygon:
Click or Spacebar on an image.
Ending a polygon:
Spacebar to end an image.

Click on the polygon
Ctrl+Click to select multiple polygons
Zoom in or out:
Adjust mouse Scroll wheel or 2 finger scroll on the trackpad

- Select all target polygons (must all be the same label) with a Ctrl+Click
- Click “g” on the keyboard
- The polygons should now be grouped.
- To reverse a grouping. Select the group and click “g”
Ctrl+Click on the 2 polygons
Click Splice tool
Select the target polygon.
Click layer front of layer back icon in the toolbar
To Use AI Auto Segmentation, Click the Auto Segmentation Icon
Now create a 4 pointed polygon, each point being at the extreme most points of the target object.
- The Highest Point
- The Lowest Point
- The Leftmost Point
- The Rightmost Point
Finally, wait for the polygon to snap into place.
To use the predictive labelling first endure AI Endpoints have been added to the project.
Then navigate to the “Predictions Tab” on the right panel. Select your prediction threshold (how confident the model must be to place a polygon)
