In step 6, a user 1002 has selected a vertex 1320 for defining a bone model longitudinal axis 1322 through the active model 1316 of a first metatarsal 208. In the illustrated embodiment, selection of a vertex 1320 is an initial step in defining a bone model longitudinal axis 1322. Next, in step 7, the system 1000 may define a plane 1324 through the selected vertex 1320 and perpendicular to the view through the canvas 1304. Next, the system 1000 may define a bone model longitudinal axis 1322 as a horizontal line from left to right that intersects the plane 1324 perpendicular to the view at the selected vertex 1320. The horizontal line is then designated, for example by the system 1000, as the bone model longitudinal axis 1322. In the illustrated example, the user 1002 has cooperated with the system 1000 to determine the bone model longitudinal axis 1322.
