Abstract:

A system and method for generating a parametric profile of an object to be modelled is shown which receives input from a user in the form of equations, generates further equations inherent to a profile definition, prioritizes the equations into ranked classes, sorts the prioritized equations to thereby create an ordered solved equation list, solves the sorted equations in the order they appear on the solved equation list and generates a profile of geometry entities constructed from the solutions of the solved equations. The system and method automatically constrain unknown variables within any under-populated equation sets based on heuristics and employ any redundant equations to determine and resolve conflicts among the equations to be used for generating the profile.
