A system, method, and computer program for selecting geometries from a solid model that is manipulated in a computer having software instructions, comprising: a computer system, wherein the computer system includes a memory, a processor, a user input device, and a display device; a computer generated geometric model stored in the memory in the memory of the computer system; and wherein the computer system selects a two-dimensional sketch geometry from a two-dimensional sketch to form a three-dimensional model using a feature command; identifies a plurality of elements on the two-dimensional sketch geometry that correspond to the three-dimensional model; forms a counterpart element on the three-dimensional model that is one of a dimension and a constraint from the identified plurality of elements; and provides the capability to modify the three-dimensional model by manipulating the counterpart element; and appropriate means and computer-readable instructions.
