网上down了一个绘制螺栓的lisp程序，加载运行后提示：错误: AutoCAD 变量设置被拒绝: "clayer" "xshx"

本人很菜，请各位高手看以下如何修改。

程序如下

;绘制螺栓 ;bolt.lsp

(defun dtr (a) (* pi (/ a 180.00)) )

;绘制螺栓头 (defun headface () (setq f (- d 0.025)) (setq dist1 (/ (- head_dia f) 2)) (setq pt27 (polar pt8 0 dist1)) (setq pt28 (polar pt7 (dtr 180) dist1)) (setq pt29 (polar pt9 0 dist1)) (setq pt30 (polar pt10 (dtr 180) dist1)) (command "line" pt29 pt27 "") (command "line" pt30 pt28 "") (setq pt31a (polar pt9 0 (/ DIST1 2))) (SETQ pt31 (polar pt31a (dtr 90) (float (/ head_thick 10)))) (setq pt32a (polar pt2 (dtr 90) head_thick)) (setq pt32 (polar pt32a (dtr 90) (float (/ head_thick 10)))) (setq pt33a (polar pt30 0 (/ dist1 2))) (setq pt33 (polar pt33a (dtr 90) (float (/ head_thick 10)))) (command "arc" pt29 pt31 pt9) (command "arc" pt30 pt32 pt29) (command "arc" pt10 pt33 pt30) (command "erase" erase_ent "") (command "line" pt31 pt33 "") )

程序我没有看，你运行程序前，先添加一个层吧，命名为xshx，再试一下

hydkot 发表于 2004-5-24 21:53:00

谢谢指点。

新建层后仍出现错误提示，但画出两条直线，如螺栓直12，则两线间距11。

继续求教。

wzh 发表于 2004-5-24 23:56:00

再加一个层:shx

hydkot 发表于 2004-5-25 21:53:00

按楼上指点可以绘出螺栓螺母了，谢谢！
