1. A method for interfacing with multiple surfaces within a computer-aided drawing environment, comprising:

  • using a computer system, determining that a first surface of a drawing comprises a first plurality of curves constituting a P×

    1 surface condition, a P×

    1 surface condition being defined by a number of first curves equal to P and only one second curve, wherein P is an integer greater than zero;

    using the computer system, determining that a second surface of a drawing comprises a second plurality of curves constituting a first N×

    M surface condition, a first N×

    M surface condition being defined by a number of third curves equal to N and a number of fourth curves equal to M, wherein N and M are integers greater than one;

    using the computer system, converting the P×

    1 surface condition of the first surface into a second N×

    M surface condition to match the N×

    M surface condition of the second surface, the second N×

    M surface condition being defined by a number of fifth curves equal to N and a number of sixth curves equal to M, wherein Nand M are integers greater than one;

    using the computer system, constructing an N×

    M surface under the second N×

    M surface condition; and

    modifying the second N×

    M surface to edit a drawing.
