Latest Patents
Fitzgerald's latest patents include a method for producing planar geometric projection images. This innovative method segments lines representing edges of model objects at intersections with contour edges of visible faces. It checks the visibility of each edge line segment against all visible faces, storing information on visibility and edge details. This approach significantly reduces the number of comparisons required, enhancing efficiency compared to prior methods.
Another notable patent is related to 3D dimensioning in computer-aided drafting. This CAD procedure allows for the modeling of a three-dimensional object using a single solid model. It presents dimensional and tolerance parameters that adapt to changes in view or parameters. The use of dogleg extension lines eliminates ambiguity in 3D dimensions, facilitating clear presentations on paper or screens. The system automatically corrects and presents axonometric views based on the operator's input.
