enum SUResult	SUDimensionLinearSetStartPoint (SUDimensionLinearRef dimension, const struct SUPoint3D *point, SUInstancePathRef path)
	Sets the start connection point of a dimension object. A dimension's connection point can be set in a few different ways. In the simplest form a connection point can be set to an arbitrary point in space by providing a non-null SUPoint3D and an invalid SUInstancePathRef. The more complex forms connect the point to a position on an entity in the model by providing a valid SUInstancePathRef which refers to an existing model entity. In the more complex forms the the input SUPoint3D must be non-null for all connectable entity types except for vertices and guide points, in which case the SUPoint3D argument may be null as it will be ignored. It should be noted that when changing a dimension's connection point the other point may need to be adjusted as well. Users may want to verify the other connection point after setting this one.
