Claim 0:
1. A computer-implemented method for simulating a manufacturing resource including a cable, the method comprising:
creating in computer memory a polyline model of a cable, the created model comprising a collection of points representing the cable;
for each point of the collection of points:
associating a point mass to the point;
associating a zero mass sphere to the point, geometry of the zero mass sphere corresponding to a dimension of the cable at a location represented by the zero mass sphere; and
assigning an elasticity and torsional stiffness between the point and adjacent points;

defining position and orientation of a start point and an end point of the collection of points representing the cable based upon position in three dimensional space of a manufacturing resource at an end of a time step; and
performing a simulation of the cable for the time step by:
computing forces on each point of the collection of points using: (i) the associated point mass, (ii) the associated zero mass sphere, (iii) the assigned elasticity and torsional stiffness between the point and adjacent points, and (iv) the defined position and orientation of the start point and the end point of the collection of points; and
determining position in three dimensional space of each point of the collection of points representing the cable at the end of the time step based on the computed forces.
