将面域旋转成球体时出错，大虾帮忙改以下

bihumanbu

Const pi = 3.1415926
Dim r As Double

 '绘制球体
 ublic Sub drwPicture()
 Dim curves(0) As AutoCAD.AcadEntity
 Dim centerpoint(2) As Double
 r = 500
 centerpoint(0) = 0: centerpoint(1) = 0: centerpoint(2) = 0
 Set curves(0) = ModelSpace.AddCircle(centerpoint, r)
 
 

 Dim object As Variant
 object = ModelSpace.AddRegion(curves)
 
 Dim solidObj As AutoCAD.Acad3DSolid
 
 Dim axisPt(2) As Double
 Dim axisDir(2) As Double
 axisPt(0) = 0: axisPt(1) = 0: axisPt(2) = 0
 axisDir(0) = 1: axisDir(0) = 0: axisDir(0) = 0
 engle = 45 * pi / 180
 solidObj = ModelSpace.AddRevolvedSolid(object(0), axisPt, axisDir, engle)

Dim newdirection(2) As Double
newdirection(0) = 1: newdirection(1) = 0.5: newdirection(2) = 0.5
ActiveViewport.Direction = newdirection
ActiveViewport = ActiveViewport

Layers.Item(0).color = AutoCAD.AcColor.acBlue
SendCommand ("_shademode" + vbCr + "_g" + vbCr)
ZoomAll
curves(0).Delete
 
 End Sub

黑体的地方出错了，高手指点一下吧，

xinghesnak

Dim curves(0) As AutoCAD.AcadEntity
 Dim centerpoint(2) As Double
 r = 500
 centerpoint(0) = 0: centerpoint(1) = 0: centerpoint(2) = 0
 Set curves(0) = ModelSpace.AddCircle(centerpoint, r)
 Dim object As Variant
 object = ModelSpace.AddRegion(curves)

这段程序创建了一个用于旋转的圆的截面吧，我查了一下VBA的例子，它用一个半圆做截面旋转就没有问题，原因我不清楚。所以我改成了下面这段程序

Dim curves(1) As AutoCAD.AcadEntity
 Dim centerpoint(2) As Double
 r = 500
 centerpoint(0) = 0: centerpoint(1) = 0: centerpoint(2) = 0

 Set ModelSpace = ThisDrawing.ModelSpace
 Dim startAngle As Double
 Dim endAngle As Double
 radius = 500
 startAngle = 0
 endAngle = pi
 Set curves(0) = ThisDrawing.ModelSpace.AddArc(centerpoint, radius, startAngle, endAngle)

 Set curves(1) = ModelSpace.AddLine(curves(0).StartPoint, curves(0).EndPoint)

下面就不会报错了。。。。

还有就是你的声明给的不全吧，什么Modelspace，SendCommand都没有声明。。。。。。下面删除曲线的程序你自己改吧。。。。。真是不知道为什么整圆不能使用。。。。。。

谢谢了按照你的方法已经成功解决了；

在cad里面好象是不能用整圆旋转，可能是旋转出的两部分相交于轴了；

但是只要轴线在圆以外就行了。

再次感谢你热心的帮助！

你好！ 你的圆转球体的代码可以共享下吗，我想将许多大小不一的圆一次性转球体， 谢谢！
