In this tutorial
unionis used to combine the purple triangles which are then cut from the blue triangle below using difference.
IIUC we could also use
unionand it has the same effect as far as the
differenceoperation. As far as boolean operations go, is the effect of using
combinealways the same?
If you have overlapping closed paths, the results will be different for Union versus Combine. If not overlapping, then there’s no difference. There can also be differences with the behaviour of Combine itself, depending on the direction of paths.
