Hi Pilou, here is another example, say I have this curve:



If I want to produce a constant distance offset of it of a certain amount, I will get this:



Notice how the offset curve has a different number of vertices and just a different structure than the starting shape?

I know it seems like it should be logical for constant thickness to mean equal structure and equal number of vertices, but there is not really a connection there - a constant thickness in many cases requires creating a shape with a different structure in it from the original.

This is also again another good example of how offset is different from scaling as well...
