大家一起完善一个粗糙度标注的程序

[复制链接]
发表于 2003-11-18 22:13:00 | 显示全部楼层 |阅读模式
刚写完了一个函数,在想是用属性块用呢还是用匿名块好呢。
因为写的时候用了匿名块,写完了了现没有必须用匿名块,好象属性块好,建立四个图块(也用程序生成),在生成时先查看是否有该名称图块存在,如果存在则直接引用,如果不存在则引用新建块函数新建一个相应的属性块。

现在把已经写好的部分贴出来。是用匿名块方法,而且也只写了一部分,还没有写到交互操作部分。

属性块应该更好,直接调用也方便
 楼主| 发表于 2003-11-19 11:46:00 | 显示全部楼层
改成了使用属性块,程序中包括了属性块的生成方法和属性块插入后的属性修改

以下为简单的程序调用部分,大家可以继续完善
Sub ic()
On Error Resume Next
Dim pnt As Variant
pnt = ThisDrawing.Utility.GetPoint(, " 选择插入点:")
Dim angle As Double
angle = ThisDrawing.Utility.GetAngle(pnt, " 选择选择角度:")
Dim txt As String
txt = ThisDrawing.Utility.GetString(0, " 请输入粗糙度大小:")
Dim mode As Integer
mode = ThisDrawing.Utility.GetInteger(" 选择粗糙度样式[表面非加工0/表面加工1]<表面非加工>:")
If Err Then
    mode = 0
    Err.Clear
End If
CreateCCD mode, pnt, angle, txt, 1
End Sub

以下为生成粗糙度的函数部分:

  1. ' 粗糙度符号标注函数
  2. ' Mode为粗糙度模式,0代表表面未加工,1代表表面加工
  3. ' InsertPoint为插入点
  4. ' Angle为插入的角度
  5. ' Value粗糙度值
  6. ' Factor为插入的比例因子
  7. Function CreateCCD(mode As Integer, InsertPoint As Variant, angle As Double, Value As String, Factor As Double) As AcadBlockReference
  8.     Dim objBlock As AcadBlock
  9.     Dim InsPnt(2) As Double
  10.     InsPnt(0) = 0: InsPnt(1) = 0: InsPnt(2) = 0
  11.     Dim BlkName As String
  12.     BlkName = "mc_ccd_" & mode
  13.     On Error Resume Next
  14.     Set objBlock = ThisDrawing.Blocks(BlkName)
  15.     If Err Then
  16.         Err.Clear
  17.         Set objBlock = ThisDrawing.Blocks.Add(InsPnt, BlkName)

  57.     If angle > Radians(90) And angle <= Radians(270) Then
  58.         objAttRef.Alignment = acAlignmentTopLeft
  59.         objAttRef.Rotate objAttRef.TextAlignmentPoint, Radians(180)

呵呵,有些难度,看着累死俺村人了:)

楼主好啊,我还是看的不是很懂

McCAD是什么意思啊?

我做的毕业设计是用VB实现粗糙度的快速标注,你说的这些事不是对我的很有用处啊?
