Curves can:■ be open or closed■ have segments are lines (linear) or curved (spline)■ be visible in player mode or not■ have a referential parallel to the grid plane (Guide) or to the view plane (View plane)■ note: there is an excellent tutorial on curves inC:\Program Files\3DVIA\Virtools 5.0\Documentation\Tutorials \TutorialAvis\Curves.avi (plays in Windows Media Player)Curve Follow BB Note that this is a Loop In/Loop Out BB. pIns include Curve & Duration pOuts are Progression & ValuePosition on Curve
