I want to be able to calculate the longest edge of a rectangle polygon to create an expression for a style.
The styled rectangles will have variable orientations, widths and lengths.
I want to use this longest length to create an expression for the spacing of the Line Pattern Fill of the polygon style. The spacing will be set to 1/3 of the longest length of the polygon, so that the rectangle is visually divided into three segments (the rotation is already set to be
As an example, the distance of the longest edge is 3.501 m, which divided by three equals 1.167 m. This value (1.167 m) is set as my spacing. The effect is what I am after, I just want to automate this without manually calculating the 1/3 of the longest edge!
