你好
我用一个函数快速分割一条线。分段四舍五入到选定的距离。
现在这个效果很好。但我有一张画有同样长度的线，只有一条分为6部分，另一条分为7部分。
我得到了两条线的vlax转储：
选择对象：；IAcadLine:AutoCAD线条界面
- ; Property values:
- ; Angle (RO) = 3.14159
- ; Application (RO) = #<VLA-OBJECT IAcadApplication 000000013fd89110>
- [color=red]; Delta (RO) = (-3000.0 9.09495e-013 0.0)[/color]
- ; Document (RO) = #<VLA-OBJECT IAcadDocument 000000002f573368>
- ; EndPoint = (-14065.0 5567.73 0.0)
- ; EntityTransparency = "ByLayer"
- ; Handle (RO) = "DB11"
- ; HasExtensionDictionary (RO) = 0
- ; Hyperlinks (RO) = #<VLA-OBJECT IAcadHyperlinks 0000000037a10f78>
- ; Layer = "HULPLIJN"
- ; Length (RO) = 3000.0
- ; Linetype = "ByLayer"
- ; LinetypeScale = 1.0
- ; Lineweight = -1
- ; Material = "ByLayer"
- ; Normal = (0.0 0.0 1.0)
- ; ObjectID (RO) = 44
- ; ObjectName (RO) = "AcDbLine"
- ; OwnerID (RO) = 43
- ; PlotStyleName = "ByLayer"
- ; StartPoint = (-11065.0 5567.73 0.0)
- ; Thickness = 0.0
- ; TrueColor = #<VLA-OBJECT IAcadAcCmColor 0000000037a13370>
- ; Visible = -1
- T
唯一的区别似乎是delta，我如何在lisp中解决这个bug？提前感谢！ |
