I need a 7-aside soccer field in my design and the only size available in the object library is much larger. I manager to change the size through the object property through its code but the markings on the field doesn't change with it and i cant figure out how!!
If you need it for one or two projects I would also suggest making it by yourself.
If you need library element you need to do in 3D tab - as on screen. There are 3 sections there for different part of the field. You probably need to adjust values of PRISM its command drawing shapes in 3d. Values are coordinates of the following vertexes.
To modify view on plan you need to do same in 2d tab.
