To create a split at the intersection of two overlapping shapes:
- Select the Split tool (). The cursor changes to a knife point ().
- Click on one of the intersections between the first and section shape (where their edges overlap). Intersections are identified by red 'X' and the 'Intersection' tooltip. The shape will briefly highlight.
- Click on another intersection between the first and second shape. The shape will briefly highlight. If there are only two intersections between the shapes, the shapes will be split and two new shapes, composed of the intersecting edges of the two intersecting shapes, is created. You can move the shapes apart to see these new shapes.
- (optional) Repeat step 3 for additional intersections between the first and second shape (if there are more than two points on the two shapes where the shapes intersect).
