发几个简化代码的函数

lijiao

近日无事,写了点代码,供大家测试一下.

程序提供了3个文件,setup.lsp    vlapi.fas  vlapi.dvb,3个文件需要放在cad的搜索路径中.

Setup.lsp是源码,主要是检索和加载文件,一看就明白.

Vlapi.dvb是vba工程文件,提供数据返回功能,大家不用关心.

Vlapi.fas是编译后的文件,提供一下几个核心函数:

(Runvba strpro [value])

(with [str/vla-object])

(wget pro)

(wput pro value)

(wmeth method [vars])

(select var)

(case var)

(Runvba strpro [value])函数的用法:

(runvba"thisdrawing.ModelSpace(0)")>>> #<VLA-OBJECT IAcadLine000001a2be9a93b8>

(runvba"thisdrawing.ModelSpace(0).layer")>>>"AM_0"

(runvba"thisdrawing.ModelSpace(0).layer" "AM_5")>>>nil

(runvba"thisdrawing.ModelSpace(0).layer")>>>"AM_5"

还可以这样用:

(runvba "userform1.showvbmodeless")

(runvba"userform1.left" 100)

(with [str/vla-object])    (wget pro)      (wputpro value)   (wmeth method [vars]) 函数的用法:

这是一组函数,调用后三个函数前,需先用with函数,比如:

(with 'cadapp)或 (with“cadapp”)均返回#<VLA-OBJECT IAcadApplication00007ff61c25b910>

(with 'thisdrawing)返回#<VLA-OBJECT IAcadDocument 000001a2b0f97298>

(with (VLAX-GET-ACAD-OBJECT))返回#<VLA-OBJECT IAcadApplication 00007ff61c25b910>

(with "thisdrawing")返回"thisdrawing."

用法示例:

(with "thisdrawing")

   (wget 'Name)或(wget “Name”)返回"Drawing1.dwg"

   (wget 'ModelSpace)或(wget“ModelSpace”)返回#<VLA-OBJECT IAcadModelSpace000001a2b0b841a8>

   (wget 'Width)或(wget”width”)返回1382

(with"thisdrawing.ModelSpace(0)")

   (wget 'layer)返回"AM_5"

   (wput 'layer "am_0")返回nil

   (wget 'layer)返回"AM_0"

(wmeth method [vars])函数的用法想必大家都明白了,只是其前面with函数的变量必须为vla-object类型

(select var)和(case var)的用法就很简单了,举例:

假如obj_line为vla-object类型的直线

(select (vla-get-color obj_line))

(Cond

   ((case 1) (princ “\n红色”))

   ((case 2) (princ “\n蓝色”))

)
