Embodiment Construction

[0025] Referring now to FIG. 1, a computer-aided design (CAD) system 10 in accordance with the principles of the present invention includes a software application running on a CPU 12 of a general purpose computer constructed, for example, from an Intel compatible processor and a Microsoft Windows operating system. Desktop computer system. Application software on the processor can be written in any number of source languages ​​such as the C++ programming language.

[0026] It will be appreciated that although the methods described herein are computer-implemented, they may not require any special computerized implementation. Those skilled in the art will appreciate that the methods and apparatus of the present invention are equally applicable to any computer system, whether the computer system is a complex multi-user computing device or a single-user device such as a personal computer or a workstation. Thus, computer systems for CAD system 10 may include IBM compatible personal...

Abstract

The invention relates to a computer aided design interface. In a CAD system, dimensions are entered as an arithmetic combination of quantities expressed in both English and metric units. The system converts the units and combines the quantities to produce the dimension. Also, an undo tool stores undo information in nonvolatile storage, so that drawing operations may be undone at any subsequent time, even after a file has been saved and retrieved, or transferred to another user. The system also associates drawn content with a paper size and orientation, rather than a specific printer, and associates each paper size and type with a printer, so that when printing a page, the paper size and type associated therewith can be used to select a printer. In this way, content may be printed on an appropriate printer based upon a paper size and orientation, without storing printer selections or details in the file.

Description

technical field [0001] The present invention relates to computer automated design (CAD) systems and their software and hardware. Background of the invention [0002] Computer automated design (CAD) systems have matured over the past few years and are now used in almost all design environments to speed up the design process and improve accuracy, benefiting not only consumers but also manufacturers. However, as useful as these systems are, their interfaces still need to be refined and improved, and challenges in using them still need to be overcome. [0003] For example, computer automated design systems are often used to design objects that are intended to match in size with existing plans. One example of this is CAD software that designs building components that fit in with existing structures. An example of CAD software commercially available for this purpose is the "DesignFast" product licensed to consumers by the assignee of the present application, which is intended fo...
