Abstract:
A mechanism is disclosed for reconstructing trimmed surfaces whose underlying spline surfaces intersect in model space, so that the reconstructed version of each original trimmed surface is geometrically close to the original trimmed surface, and so that the boundary of each respective reconstructed version includes a model space trim curve that approximates the geometric intersection of the underlying spline surfaces. Thus, the reconstructed versions will meet in a continuous fashion along the model space curve. The mechanism may operate on already trimmed surfaces such as may be available in a boundary representation object model, or, on spline surfaces that are to be trimmed, e.g., as part of a Boolean operation in a computer-aided design system. The ability to create objects with surface-surface intersections that are free of gaps liberates a whole host of downstream industries to perform their respective applications without the burdensome labor of gap repair, and thus, multiplies the efficacy of those industries.

Claim (Index 1):
A computer-implemented method for modifying a computer-aided design (CAD) model of a tangible object, the method comprising:\n performing, by the computer:\n storing geometric input data describing first and second input surfaces associated with the CAD model, wherein the first and second input surfaces are described in a first and second parameter space domain, respectively; \n constructing an output surface as a representation of at least portions of the first and second input surfaces, respectively, wherein the output surface is described in a third parameter space domain, wherein constructing the output surface comprises:\n constructing a third set of isocurves corresponding to the output surface, wherein the third set of isocurves is determined based at least in part on a first set of isocurves of the first input surface and a second set of isocurves of the second surface; and \n \n storing a modified CAD model of the tangible object comprising the output surface, wherein the modified CAD model is watertight around a geometric intersection of the first and second input surfaces.
