1. A method of tracking a state of a physical as built feature of a residential structure in a CAD Virtual Model, the method comprising;

  • a) determining a geographic position of a physical residential structure via a global positioning system device in a smart device held by a User proximate to or within the residential structure;

    b) identifying a digital virtual model of the residential structure based upon the geographic position of the residential structure, the digital model comprising the CAD virtual Model of structural components included in the residential structure;

    c) referencing multiple positioning reference devices within the residential structure;

    d) measuring a distance from the smart device at a first point of measurement to at least three of the multiple positioning reference devices;

    e) specifying a first position of a smart device held by a User at a Vantage Point within the residential structure, the first position based upon first respective distances of the at least three positioning reference devices to the first position of the smart device and a triangulation calculation;

    f) calculating an elevation of the smart device at the first position;

    g) specifying a direction of an as built feature via the User positioned at the Vantage Point extending the smart device from the first position comprising a base position to a second position comprising an extended position;

    h) measuring a distance from the smart device at the second position to the at least three of the multiple positioning reference devices;

    i) specifying a second position within the residential structure, based upon second respective distances of the at least three positioning reference devices to the second position of the smart device;

    j) measuring a first state of the as built feature with the smart device at one of;

    the first position and the second position along the direction of the as built feature specified by movement of the smart device from the first position to the second position with a sensor controlled by the smart device;

    k) specifying a location of the first state within the residential structure via reference to the position of the first point of measurement, the elevation of the first point of measurement and a distance in the direction of the as built feature;

    l) recording a time designation for the step of measuring a first state of the as built feature with the smart device within the residential structure;

    m) generating a virtual representation of the as built feature within the CAD virtual model;

    n) displaying the virtual representation of the physical as built feature on a display based upon a query input by the User.
