【摘要】 CAD图形的局部拷贝缩放功能的开发是基于VisualLisp语言基础上的二次开发,主要地解决工程设计绘图中需要精确显示和标注的局部图形。阐述了利用VisualLisp语言在AutoCAD软件平台上,对选中的局部CAD图形拷贝和缩放,然后在修剪所选局部图形范围外的实体部分,开发出CAD图形局部拷贝缩放功能系统的过程。更多还原

【Abstract】 The development of part copy and scale function in CAD drawing is based on Visual Lisp language quadratic development,which mainly solve the problem that need precise showed and labeled in CAD engineering design drawing.It explains that using Visual Lisp language on the AutoCAD software platform to copy and scale part CAD drawing which is selected and cut out the entities out of selected drawing.Finally using Visual Lisp language develop the part copy and scale function of CAD drawing.更多还原
