求救：请CAD的LISP高手帮忙

;平面图转换成45度透视图
;增加角度转换.块或者字体.

兄弟，问题搞复杂了。

AutoCAD本身就是三维辅助设计软件，直接通过模型空间建模，图纸空间做轴测图就好了。功能比用LSP强大多了。

你在走前的弯路了……

中国国内很多的AutoCAD教学，有问题的。

(setq ss (ssget "x" '((0 . "text")(cons 62 1) (-4 . "=") (40 . 5)))) ;红色 (setq ss (ssget "x" '((0 . "text")(cons 62 255) (-4 . "=") (40 . 5)))) ;黑色 颜色就按 color中的颜色序号设置
