I thought I could do this easily with SCALE1D but it seems it does not work like I thought it did.
I have a polygon, four sides, four vertices. I want to scale this polygon in y direction, increasing only its height, maintaining its proportions and angles. I want the length of the piece to be fixed also.
Here I used SCALE1D, but the angle of the shape changed, it got deformed. Its logical because you are scaling in 1D. But I want this to work as if it was a regular rectangle, just keeping its width and angles fixed, increasing the height on both opposites sides.
