  • Publication number: 20170263034
    Abstract: Systems and methods for computer-aided or virtual drafting and design are described. Such systems and methods provide a virtual drafting space with the capability of providing multiple layers, magnifications, and scale sensitivity such that a draftsperson can navigate through the virtual drafting space through simple touch commands on a multi-touch interactive screen or through other inputs. As the draftsperson changes the magnification environment of the drawing, the systems and methods provide a set of drafting instruments calibrated for use with the particular environment chosen and scale within that environment, including a stencil capable of being locked to correlate to its scale in the virtual environment regardless of magnification level.
