Selected closed vectors that overlap can be merged together to create a new shape. These tools consider the closed vectors to be solid areas.
The following examples begin with these five vector shapes where the rectangle was selected last.
Welds overlapping vectors together to create a new shape which follows the outermost edge of all the selected shapes.
When welding text, the internal regions of characters are preserved.
Overlapping text before welding
Overlaps removed by welding, but internal regions preserved
