有人会CAD的VBA编辑吗？
我这里有2个三维模型需要用VBA来编写，有哪位高手会的？[ 本帖最后由 绯村剑心 于 2010-1-28 11:31 编辑 ] 什么意思？？？看不明白！ 正在学习中。 要用CAD里面的宏（VBA）来编辑出上面的图？尺寸都在上面有了~！
有谁会做的啊？ 正在学，现在做不了，呵呵 没人高手会的吗？:(
有在上海的可以当面支付报酬！ 第一个图
Dim objBox As Acad3DSolid, objSphere As Acad3DSolid, dblCenter(2) As Double
With ThisDrawing.ModelSpace
Set objBox = .AddBox(dblCenter, 100, 100, 100)
dblCenter(1) = 50
Set objSphere = .AddSphere(dblCenter, 45)
objBox.Boolean acSubtraction, objSphere
ZoomAll
End With
第二个图
Dim dblVerticesList(17) As Double, objLWPLine(0) As AcadLWPolyline, varRegions As Variant, dblAxisPoint(2) As Double, dblAxisDir(2) As Double
With ThisDrawing
.SendCommand "ucs w "
dblVerticesList(0) = 30
dblVerticesList(2) = 100
dblVerticesList(4) = 100: dblVerticesList(5) = 25
dblVerticesList(6) = 95: dblVerticesList(7) = 30
dblVerticesList(8) = 65: dblVerticesList(9) = 30
dblVerticesList(10) = 60: dblVerticesList(11) = 35
dblVerticesList(12) = 60: dblVerticesList(13) = 95
dblVerticesList(14) = 55: dblVerticesList(15) = 100
dblVerticesList(16) = 30: dblVerticesList(17) = 100
Set objLWPLine(0) = .ModelSpace.AddLightWeightPolyline(dblVerticesList)
objLWPLine(0).Closed = True
objLWPLine(0).SetBulge 2, Tan(.Utility.AngleToReal(90 / 4, acDegrees))
objLWPLine(0).SetBulge 4, Tan(.Utility.AngleToReal(-90 / 4, acDegrees))
objLWPLine(0).SetBulge 6, Tan(.Utility.AngleToReal(90 / 4, acDegrees))
varRegions = .ModelSpace.AddRegion(objLWPLine)
objLWPLine(0).Delete
dblAxisDir(1) = 1
.ModelSpace.AddRevolvedSolid varRegions(0), dblAxisPoint, dblAxisDir, .Utility.AngleToReal(180, acDegrees) * 2
varRegions(0).Delete
ZoomAll
End With

第一个看到了~！可是第二个运行不出来~！:( 第二个图形出不来,可能是因为你的CAD版本太老了吧?
在早期CAD中,LWPolyline(二维多段线)对象使用三维坐标,而现在常见的版本中该对象已经优化,改为使用二维坐标.7楼代码就是用二维坐标设计的.如果在早期版本中运行该代码,应该把多段线顶点坐标数组改为三维的形式,如下
Dim dblVerticesList(26) As Double, objLWPLine(0) As AcadLWPolyline, varRegions As Variant, dblAxisPoint(2) As Double, dblAxisDir(2) As Double
With ThisDrawing
.SendCommand "ucs w "
dblVerticesList(0) = 30
dblVerticesList(3) = 100
dblVerticesList(6) = 100: dblVerticesList(7) = 25
dblVerticesList(9) = 95: dblVerticesList(10) = 30
dblVerticesList(12) = 65: dblVerticesList(13) = 30
dblVerticesList(15) = 60: dblVerticesList(16) = 35
dblVerticesList(18) = 60: dblVerticesList(19) = 95
dblVerticesList(21) = 55: dblVerticesList(22) = 100
dblVerticesList(24) = 30: dblVerticesList(25) = 100
Set objLWPLine(0) = .ModelSpace.AddLightWeightPolyline(dblVerticesList)
objLWPLine(0).Closed = True
objLWPLine(0).SetBulge 2, Tan(.Utility.AngleToReal(90 / 4, acDegrees))
objLWPLine(0).SetBulge 4, Tan(.Utility.AngleToReal(-90 / 4, acDegrees))
objLWPLine(0).SetBulge 6, Tan(.Utility.AngleToReal(90 / 4, acDegrees))
varRegions = .ModelSpace.AddRegion(objLWPLine)
objLWPLine(0).Delete
dblAxisDir(1) = 1
.ModelSpace.AddRevolvedSolid varRegions(0), dblAxisPoint, dblAxisDir, .Utility.AngleToReal(180, acDegrees) * 2
varRegions(0).Delete
ZoomAll
End With
如果要求程序运行的最后得到像1楼附图一样的显示结果,可以给三维实体赋予指定的颜色,并调用图形界面的"着色"命令改变视图的显示模式.还可以改变视图方向,如下
Sub A()
Dim objBox As Acad3DSolid, objSphere As Acad3DSolid, dblCenter(2) As Double
With ThisDrawing.ModelSpace
Set objBox = .AddBox(dblCenter, 100, 100, 100)
dblCenter(1) = 50
Set objSphere = .AddSphere(dblCenter, 45)
objBox.Boolean acSubtraction, objSphere
objBox.color = 152
MyDisplay
End With
End Sub
Sub B()
Dim dblVerticesList(17) As Double, objLWPLine(0) As AcadLWPolyline, varRegions As Variant, dblAxisPoint(2) As Double, dblAxisDir(2) As Double, obj3DSolid As Acad3DSolid
With ThisDrawing
.SendCommand "ucs w "
dblVerticesList(0) = 30
dblVerticesList(2) = 100
dblVerticesList(4) = 100: dblVerticesList(5) = 25
dblVerticesList(6) = 95: dblVerticesList(7) = 30
dblVerticesList(8) = 65: dblVerticesList(9) = 30
dblVerticesList(10) = 60: dblVerticesList(11) = 35
dblVerticesList(12) = 60: dblVerticesList(13) = 95
dblVerticesList(14) = 55: dblVerticesList(15) = 100
dblVerticesList(16) = 30: dblVerticesList(17) = 100
Set objLWPLine(0) = .ModelSpace.AddLightWeightPolyline(dblVerticesList)
objLWPLine(0).Closed = True
objLWPLine(0).SetBulge 2, Tan(.Utility.AngleToReal(90 / 4, acDegrees))
objLWPLine(0).SetBulge 4, Tan(.Utility.AngleToReal(-90 / 4, acDegrees))
objLWPLine(0).SetBulge 6, Tan(.Utility.AngleToReal(90 / 4, acDegrees))
varRegions = .ModelSpace.AddRegion(objLWPLine)
objLWPLine(0).Delete
dblAxisDir(1) = 1
Set obj3DSolid = .ModelSpace.AddRevolvedSolid(varRegions(0), dblAxisPoint, dblAxisDir, .Utility.AngleToReal(180, acDegrees) * 2)
varRegions(0).Delete
obj3DSolid.color = 135
MyDisplay
End With
End Sub
Private Sub MyDisplay()
Dim objUCS As AcadUCS, dblOrigin(2) As Double, dblXAxisPoint(2) As Double, dblYAxisPoint(2) As Double
dblXAxisPoint(0) = 1: dblXAxisPoint(1) = 0: dblXAxisPoint(2) = -1
dblYAxisPoint(0) = -1: dblYAxisPoint(1) = 2: dblYAxisPoint(2) = -1
Set objUCS = ThisDrawing.UserCoordinateSystems.Add(dblOrigin, dblXAxisPoint, dblYAxisPoint, "U")
ThisDrawing.ActiveUCS = objUCS
ThisDrawing.SendCommand "plan c ucs w shademode g "
ZoomAll
End Sub
上面代码中宏"A"和"B"分别是画1楼两个图形的代码."MyDisplay"是供两个宏运行到最后调用的子程序,用于修改视图方向和修改视图为"体着色"模式.
由于CAD2007以上版本中,"shademode"命令已被改为调用"视觉样式"命令,所以,如果在2007以上版本中运行本代码,应把ThisDrawing.SendCommand "plan c ucs w shademode g "一行,改为
ThisDrawing.SendCommand "plan c ucs w -shademode g "
请注意,新的代码中,第二个图形中的多段线仍然使用的是二维坐标,如果在早期版本中使用,应按前面所说的方法修改.
[ 本帖最后由 woaishuijia 于 2010-2-2 14:31 编辑 ] 楼上的大侠，本人实在对这个很不懂，我在运行第二个的时候就出现个错误！不知道什么意思？
有QQ吗？加QQ说吧。我的是64336396 我用的是省略用法.可能是版本或电脑环境的关系吧,我在2005和2010上用都没有问题.
在前面加上一个".",应该可以了.
.SendCommand "ucs w "
另:前面帖子中相应的部分已更改,重新复制吧
[ 本帖最后由 woaishuijia 于 2010-2-2 14:33 编辑 ] 恩~！我刚又试过你11楼的后面代码的2个图型都出来~！:) 真是太感谢你了！
想自己再研究下你写的代码，就是实在看不懂啊~！:Q 学习了，谢谢你们众多位
