What is it about?

For some time now, polygons can be merged and also separated again. These functions are known in Stylo under the functionalities "Merge" and "Split". Through this function, an exclusion could also be defined. However, more complex possibilities cannot be achieved through merging or only with a lot of effort.

How does it work?

1. Draw polygons – the number is not limited to two.
   (Please do not use the traditional rectangles, ellipses, etc. The elements must come from the section polygons or shapes.)
2. Open the context menu (usually the right mouse button) and select "Merge".
3. A unified polygon is created.
   Up to this point, the polygon can still be returned to its original components using "Split". Once you make changes by combining, this is no longer the case.
4. Open the context menu and select the "Paths" function. Choose the function that best suits your goals. The various path operations are described in the following section.
    

What path operations are there?

Regarding the illustrations: On the left the original object, on the right the object after applying the path operation.

Union
The paths are combined into a single object. Overlapping areas merge, resulting in a new path that only shows the outer overall contour. Inner overlapping lines disappear.

Intersection
Only the area where the paths overlap is retained. This creates a new path; all areas outside the intersection are removed.

Difference
With "Difference", the top object is subtracted from the one below. The top object itself completely disappears – where it covered the bottom one, it punches out a hole. What remains is only the bottom object with the cut-out shape.

Exclusion
The paths are combined into one object, with the overlapping area left out (transparent). Thus, only the areas that do not overlap remain.
