It is considered while checking different constraints like [Boundary Check](https://help.rhinonature.com/scopes#boundary-check) or [Collisions](https://help.rhinonature.com/manual/distribution/collisions).\ **Local Scale** - Determines the initial scale of the selected entity.\ **Local Offset** - Controls the initial offset of the selected entity along its Z-axis. Useful for eg. when creating leaves layer laying on the lawn.
