一点相对于另一点
在这个lisp中，我试图替换4个块，它们几乎做相同的事情。我想让用户点击他们想要用作文本中心的点，让代码计算出一定的距离，比如说，下一行文本的Y轴上的3.5。;INSERT STREET NAME & R.O.W.

(vlax-put-property oText 'TextString newchg)
(vlax-invoke-method oText 'Update)
)
)

) 从VL中可以得到的一个信息是“Vla get Insertionpoint txt”，然后只需使用极坐标来计算下一个文本点。 哇，伙计！谢谢那太棒了！

) 只是一个建议，你的方法适用于OSNAP真的没关系
.
(setvar "osmode" 0) ; no snaps
(setvar "osmode" 47) ; (command ".osnap" "NOD,end,INT,CEN,mid")
;just set osnaps then OSMODE will give number
;also
(setq oldsnap (getvar "osmode"))
(setvar "osmode" oldsnap)
