I would like to edit the dimensions of the "General Sport Area" so that it has round edges (not square appearance), should suit the used for a hockey arena.
Is this possible ?

Hello Tomash,

We would like to inform you that it is not possible. You have only the option to edit the grid points manually:
Choose the area -> Right click -> Edit Grid points.

Best regards
