Drawing defaults and interaction radii
Set standard device/comment dimensions and hit-test or port-spacing settings.
Use
Project Settings > Drawing defaults includes Default node width, Default node height, Default comment width, and Default comment height. Port hit radius, Edge hit radius, and Flag hit radius control how nearby geometry can be targeted. Port vertical gap sets normal port spacing.
Effect
Defaults guide operations that use them; changing a default is not a blanket resize of every existing object or a replacement for editing the current draft's Size. Hit radii affect picking sensitivity, not exported object dimensions. Existing local port offsets can be reset separately. See [ Numbers, coordinates, and sizes ], [ Select canvas objects ], and [ Reset styles and port offsets ].
