How to Use the Brush
The Brush tool is only available for drawing in the Single slice view layout, and remains inactive in other layouts.
Select an object in the list.
In the single slice view, center and zoom to the region of interest using the Zoom, Scroll and Pan functions.
Adjust the brush size if necessary.
Use a brush stroke to expand the object outline to a preferred size.
If edges of the segmented area are not correctly separated from the surrounding area, use Erase to define these borders more accurately.
The right mouse button can be used to erase when Brush is active.
Scroll to the next slice. Repeat steps 4-6 until the object has been created in all relevant slices.
Verify the object in all 2D slices.
