[求助]简单图形程序

<p>以常要画这些零件，小弟初学lisp程序，写了一个如下</p><p>(defun c:ss ()<br/>(setq a1 (getpoint "请输入角点:"))<br/>(setq ll (getdist a1 "\n 请输入长度:"))<br/>(setq ww (getdist a1 "\n 请输入宽度:"))<br/>(setq hh (getdist a1 "\n 请输入高度:"))</p><p>(setq a4 (polar a1 0 ll))<br/>(setq d4 (polar a4 (/ pi 2) ww))<br/>(setq d1 (polar d4 pi ll))<br/>(command "rectang" a1 d4 "")</p><p>(setq a5 (polar a1 0 (+ ll 80)))<br/>(setq a7 (polar a5 0 hh))<br/>(setq d7 (polar a7 (/ pi 2) ww))<br/>(setq d5 (polar d7 pi hh))<br/>(command "rectang" a5 d7 "")</p><p>(setq a2 (polar a1 0 20))<br/>(setq b2 (polar a2 (/ pi 2) (/ (- ww 64) 2)))<br/>(command "circle" b2 5 "")</p><p>(setq d2 (polar d1 0 20))<br/>(setq c2 (polar d2 (/ (* 3 pi) 2) (/ (- ww 64) 2)))<br/>(command "circle" c2 5 "")</p><p>(setq a3 (polar a4 pi 20))<br/>(setq b3 (polar a3 (/ pi 2) (/ (- ww 64) 2)))<br/>(command "circle" b3 5 "")</p><p>(setq d3 (polar d4 pi 20))<br/>(setq c2 (polar d3 (/ (* 3 pi) 2) (/ (- ww 64) 2)))<br/>(command "circle" c2 5 "")</p><p>(setq a6 (polar a5 0 (/ hh 2)))<br/>(setq b6 (polar a6 (/ pi 2) (/ (- ww 64) 2)))<br/>(command "circle" b6 5 "")</p><p>(setq d6 (polar d5 0 (/ hh 2)))<br/>(setq c6 (polar d6 (/ (* 3 pi) 2) (/ (- ww 64) 2)))<br/>(command "circle" c6 5 "")</p><p>)</p><p>但加载后运行，两个矩形是画出来了，可是孔的位置不对，请各位帮帮忙，问题出在哪里？谢谢!</p>
