Hi Tom, there isn't any setting currently in moi.ini to do that.

But it is possible to alter the default by updating a script file - I've attached a file DefaultToDiameter.zip that will do that. Unzip it to get a new RadiusDiameter.js file, and then copy this one over top of the old version under the \commands subfolder inside of MoI's main installation folder.

I will also see about adding an .ini switch for this as well, since the above solution is something that you would have to repeat with each new beta release. But that should do the job for the moment anyway.
