I searched around for any threads relating to this, but perhaps I'm using the wrong terminology.
The wording of movement tends to suggest that circular movement is not possible within the game (models move according to the center of their front arc, in that direction and measured from there). First, is this understanding correct? So bendy tape measures and such forms of measurement are explicitly forbidden?
Secondly, if the above is true, and you have two models(A and B) in base to base contact, and a third model (C) some distance away, all of which align such that a straight line can be drawn through the 3 center points of the models. Can the model that is furthest away from model C move "towards" model C? If you can't move in a circular manner, then mathematically, this would be impossible (any movement while the 2 bases are tangent would cause an overlap, unless the first movement is along a perfect horizontal line, which would fail at moving "towards" model C).
