DetachCspline脚本下载链接https://pan.baidu.com/s/1ps8tzsRNHteBMVtogIxUEg
DetachCspline脚本，3dsmax
脚本放入2个文件夹，第一个位置：将下载的DetachCspline脚本放置在3dsmax的脚本文件夹下面C:\Program Files\Autodesk\3ds Max 2012\Scripts第二个位置：将下载的DetachCspline脚本再放置在C:\Program Files\Autodesk\3ds Max 2012\UI\MacroScripts下。其他版本也是一样的关键是在MacroScripts和Scripts文件夹里面
设置快捷键，重新！！！打开max，找到菜单栏customize>>customize user interface;进入对话框后在选项keyboard>>category下拉框下面找到DetachCspline，这个就是刚刚放进去的脚本；我设置的快捷键是D
macroScript DetachCspline category:'DetachCspline' toolTip:'DetachCspline'( for a in selection do ( if classof a==Editable_Poly and subobjectLevel==5 then (macros.run 'Editable Polygon Object' 'EPoly_Detach') else if classof a==Editable_Poly and subobjectLevel==4 then (macros.run 'Editable Polygon Object' 'EPoly_Detach') else if classof a==Editable_Poly and subobjectLevel==3 then(macros.run 'Editable Polygon Object' 'EPoly_ShapeFromEdges') else if classof a==Editable_Poly and subobjectLevel==2 then(macros.run 'Editable Polygon Object' 'EPoly_ShapeFromEdges') else if classof a==Editable_Mesh and subobjectLevel==5 then (macros.run 'Editable Mesh Object' 'EMesh_Detach') else if classof a==Editable_Mesh and subobjectLevel==4 then (macros.run 'Editable Mesh Object' 'EMesh_Detach') else if classof a==Editable_Mesh and subobjectLevel==2 then (macros.run 'Editable Mesh Object' 'EMesh_ShapeFromEdges') else if (classof a==SplineShape and subobjectLevel == 3 ) then (macros.run 'Editable Spline Object' 'ESpline_Detach_Spline') else if (classof a==SplineShape and subobjectLevel == 2) then (macros.run 'Editable Spline Object' 'ESpline_Detach_Segment') ) )也可以考入源码，后缀名保存为ms格式；全名为DetachCspline.ms
使用方法：选择要分离的线或者面或者轮廓或者元素后点击 菜单栏maxscript>>run script运行脚本即可如果设置了快捷键可以直接按快捷键，我的是D所以可以使用D
