Trajpar: Trajectory Parameter is a variable that goes from a value of 0 to 1 and is used for relations for sections of Variable Section Sweep.

It allows the user to vary the x section or location of x section of the sweep. For instance you can create a VSS cone using a straight line trajectory and pivot plane and have an equation

d#=10-10*trajpar that controls the x-sec diam of the cone.
