【摘要】 针对采矿矿图种类繁多、内容多变、重复性强的特点,对AutoCAD的底层机制进行研究,利用计算机程序语言VB,建立了矿图图元的计算机绘制模型,使其能够添加到所需要绘制的采矿图中,并且能够自动完成文字标注和图形旋转、缩放。此方法与采矿线型库结合,可完成复杂的采矿矿图的全部绘制工作,为在实践中推广采矿计算机辅助设计奠定了基础。更多还原

【Abstract】 Directed at the characters of mining map, such as many species, changeble content, strong repetition, the paper introduces the research into the bottom mechanism of AutoCAD, and an attempt to build the computer drawing model of mining map picture element by using the computer program language Visual Basic. The model allows to be added to the required drawing mining map. It can also accomplish characters mark and the graph revolving and zoom automatically. It introduces the reality method and the steps. The combination of the method with the mining linear warehouse serves to accomplish the drawing of complicated mining map and forms the base of spreading mining computer assistant design in practice.更多还原
