Simple Glyphs - Join and Split Contours

Both Contour mode and Point mode have ways to combine and split contours. Usually Union, Intersection and Exclusion, available in Contour mode, and Knife, available in both modes, are recommended. If these features don't give expected results then Split Self Intersecting Contours available in Contour mode or Join Contours and Split Contour available in Points mode might help.

Union, Intersection and Exclusion in Contour mode

Use the Union feature to merge several overlapping contours.

Use the Intersection feature to keep all overlapping parts.

Use the Exclusion feature to remove all overlapping parts.

Using the knife tool in both modes

Use the knife tool to cut contours. Hold down the Shift key while using the knife tool to constrain the angle of cuts to 15°multiples.

Split Self Intersecting Contours

This feature is especially useful if you have a self intersecting contour that has a small part that is unwanted. This feature will split the contour, so you can then select the unwanted part, and remove it.

 

Join Contours and Split Contour in Point mode

When you want to combine two contours you have to select one point on each contour. Next right-click one of these points and click "Join Contours" on the shortcut menu.

 

To split a contour into two contours, select two points (these points should not be neighbors) on the same contour and then right-click one of these points and click "Split Contour" on the shortcut menu.

 

Note: Make sure the two combining contours have the same direction.

 

Note: Union, Intersection, Exclusion and Knife are not available in the Home Edition of FontCreator.

 

Note: Union, Intersection, Exclusion and Knife only work with contours made out of quadratic Bézier curves. If you use them with cubic curves, FontCreator will convert those contours to quadratic.
