剖面线。lsp不'；t r
大家好，我尝试了这个lisp文件，它工作得很好，只是无论我的dimscale设置如何，它都绘制相同的高度箭头和文本。我试着玩变量，并得到箭头和线的比例来调整，但似乎没有任何工作的文字高度。我不是一个Lisp程序的人；谁能告诉我如何修改它，使lisp根据dimscale设置绘制？

;;; Three styles of section lines each with optional annotation or
;;; section/grid/page markers. Optional "SECTION X-X" tag too.
;;;
;;; Makes a new SectionLine layer and is based on your DIMSCALE setting.
;;;
;;; SE1 is the old standard dashed lines and arrowheads.
;;;
;;; SE2 is a modified ISO style. Pick two points to control the
;;; direction of the view.
;;;
;;; SE3 is a free form ziggity-zaggity section line. Pick a bunch
;;; of points to form the cut, and then select the viewing angle.

只是一个猜测，尝试删除该行：
（setvar“dimscale”2.0）
或者将dimscale设置为任何您不希望的值。
