Virtual drafting tools

摘要

Various disclosed embodiments include methods and systems for creating a virtual geometric model. According to disclosed embodiments, a data processing system for creating a virtual geometric model includes at least one processor and a memory connected to the processor. The data processing system is configured to generate a virtual drafting tool and a virtual marking device. The data processing system is configured to position the virtual drafting tool on a page and to position the virtual marking device relative to the virtual drafting tool. The data processing system is configured to draw the geometric model on the page by laying down ink by the virtual marking device using the virtual drafting tool and to store the geometric model in the memory.

主权项

1. A method for creating a virtual geometric model using a computer aided design (CAD) system, comprising:
positioning a virtual drafting tool; positioning a virtual marking device relative to the virtual drafting tool; creating a guide edge along the external edge of the virtual drafting tool; creating a masked area bounded by the guide edge, wherein the virtual marking device is prevented from laying down ink under the masked area; drawing the geometric model on a page by laying down ink by the virtual marking device using the virtual drafting tool; and storing the geometric model in a memory.
