Thanks, that explanation is very helpful. Although the component edge cutouts can certainly be implemented, I doubt it's a commonly used feature. I'll forget about that use case then. I'll look at the BuildBoard3DView(); thanks for the tip. - Cirilo _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
