        Point to Curve (PTCV)
        A point to curve joint consists of a fixed point on one body sliding on a curve that is fixed on a second body. The point is not allowed to lift off the curve. The curve on the second body should be a 3D curve and needs to be specified using a HyperWorks curve (which is a reference entity).
        
        Curve to Curve (CVCV)
        The curve to curve constraint consists of a 3D curve fixed on one body rolling and sliding on a 3D curve fixed on a second body. The curves are required to have a unique point of contact and a common tangent at that point of contact. The curve-to-curve constraint is useful for modeling cams where the point of contact between two parts changes during the motion of the system. The curves always maintain contact, however, even when the physics of the model might dictate that one curve lift off the other.
        
        Point to Surface (PTSF)
        A point to surface joint constrains a fixed point on a body to slide along a surface. The point to surface joint provides five degrees of freedom: three rotational at the instantaneous point of contact and two translational DOF.
        
        Curve to Surface (CVSF)
        The curve to surface joint provides five degrees of freedom: three rotational at the instantaneous point of contact and two translational DOF.
        
        Surface to Surface (SFSF)
        The surface to surface constraint consists of a surface on one body rolling and sliding on the surface of a second body. Each of the surfaces are required to have a unique contact point. The surface to surface joint constrains the two surfaces as follows: the surfaces have exactly one contact point, and the normal at the contact point for each is anti-parallel.
        
        Point to Deformable Curve (PTDCV)
        The point to deformable curve joint constrains a fixed point on a body to slide along a curve that passes through the origins of a specified set of markers. These markers may belong to different bodies. As the markers move in space, the curve is calculated at every time step using CUBIC spline interpolation through the marker origins. Hence, the curve deforms as the markers move about.
        
        Point to Deformable Surface (PTDSF)
        The point to deformable surface joint constrains a fixed point on a body to slide along a surface that passes through the origins of a specified set of markers. These markers may belong to different bodies. As the markers move in space, the surface is calculated at every time step using CUBIC spline interpolation through the marker origins. Hence, the surface deforms as the markers move about.
        
        Constraint Mates
