Arkio settings can be accessed from the bottom drawer of the main menu. Here you can change the general units of Arkio to be metric (meters) or imperial (decimal feet) and change the default sizes of your walls (hollow shapes) and floors (stacked shapes)
The active version of Arkio and additional settings for troubleshooting can be found in the second tab of the setting dialog. Usage analytics sends us anonymous information about the performance and crashes of the app that will be used for improving Arkio's stability. The performance monitor can be used to see the active framerates and troubleshoot potential issues with slow performance in the app. Note however that the performance monitor doesn't display fully accurate numbers as the display of the monitor itself can result in some loss of performance.
