1、CAD的cal计算器的简单应用在旋转命令中的应用启动cal命令表达式的方法。在下面的图中，我们把底面的直线旋转到上面的角度的一半，图上已经标注好了60度，假如我们不知道这个度数，就可以用表达式计算并旋转图形。选择直线，输入ro,空格，选择基点，yearsmortgagehousing;4.mortgageregistrationformalitiesarecompleted.(D)pledge1.borrower(includingthepledgor)between18-65yearsofage,withfullci

2、vilcapacity;2.collateral这个时候输入‘cal空格，输入表达式1/2*ang(end,end,end)yearsmortgagehousing;4.mortgageregistrationformalitiesarecompleted.(D)pledge1.borrower(includingthepledgor)between18-65yearsofage,withfullcivilcapacity;2.collateral输入好后按空格，提示图元捕捉，应该先选取角的顶点，再按逆时针方向选选取两

3、边的端点，yearsmortgagehousing;4.mortgageregistrationformalitiesarecompleted.(D)pledge1.borrower(includingthepledgor)between18-65yearsofage,withfullcivilcapacity;2.collateral已经按照需要旋转过来了，我们把这个线放到角里，加上标注，如下图，yearsmortgagehousing;4.mortgageregistrationformalitiesarecomp
