i want the upper and lower edge to keep the same distance, and the left-right edge i want them to be cut around 10mm. It would be better if i can change the number.i think it is not just simply scale down. but i don’t know how to do.
Are you looking for something like this?
Both lateral curves (red) are selected manually though.
