【Abstract】 Computer drawing is a newly-established applied technology basic course adapted to the reform of the engineering drawing course. It applies a computer to make an engineering drawing, mainly by the use of a general drawing software. Because of the limitation of the general software, computer drawing cannot completely meet the needs of engineering drawing. The article introduces a computer drawing assisted instruction system for the second-time development on the basis of general drawing software AutoCAD, which may be applied in the process of teaching.更多还原
