CATIA二次开发VBA入门（3）——进程外开发环境搭建，vb.net在Visual Studio中开发，创建圆柱曲面的宏录制到二次开发案例

---

vb.net和vb6.0

VB.NET一种简单，现代，面向对象计算机编程语言，有微软开发，VB.NET是一种基于.NET Framework的面向对象编程语言，它是Visual Basic语言的继承者，但是与早期版本的Visual Basic有很大的不同。VB.NET是一种强类型语言，支持类、接口委托、异常处理、LINQ等现代编程特性，可以开发Windows应用程序、Web应用程序、服务和组价。它还支持多线程和异步编程，并且可以与其他的.NET语言(如C#)进行交互。VB.NET是一种易学易用的语言,适合初学者和专业开发人员

特点:

1.面向对象：VB.NET 是一种完全面向对象的语言，支持封装、继承和多态等面向对象的特性。

2.强类型：VB.NET 是一种强类型语言，需要在编译时进行类型检查，避免在运行时出现类型错误。

3.安全性：VB.NET 具有良好的安全性，支持代码访问权限控制、类型安全、内存管理等功能，可以有效地防止程序运行时出现安全问题。

4.可扩展性：VB.NET 可以轻松地扩展和定制，可以使用 COM 组件、.NET 组件和自定义组件等方式扩展应用程序的功能。

5.多平台支持：VB.NET 可以运行在多个操作系统上，包括 Windows、Linux 和 macOS 等。

6.集成开发环境：VB.NET 可以与 Visual Studio 集成使用，提供了丰富的开发工具和调试功能，可以提高开发效率和代码质量。

7.数据库支持：VB.NET 提供了对多种数据库的支持，包括 ADO.NET、OLE DB 和 ODBC 等，可以方便地访问和操作数据库

VB.NET和VB6.两种不同的Visual Basic版本，它们在语言、架构、开发环境、应用场景等方面都有很大的差异。

不同之处
类型	语言	架构	开发环境	应用场景	编译器	文件格式
VB.NET	完全面向对象语言支持更多语言:泛型,LINNQ,匿名来类型	.NET Framework支持更多.NET Framework特性：Windows Forms,WPF,ASP.NET	Visual Studio	构建大型的企业级应用用程序	.NET	VB或VB.ET
VB6.0	基于事件语言	COM	集成开发环境(IDE)	小型的应用程序和系统内的维护和升级	Microsoft Vissual Basic 6.0	.frm、.cls.bas等

进程外开发环境搭建

vb.net开发环境搭建

• 新建模块

创建了窗口和模块

《CATIA二次开发技术基础》模板

Imports INFITFModule Module1Public CATIA As INFITF.ApplicationPublic Sub Main()On Error Resume Next '有错误的话会忽略，继续执行下一句 ' 如果打开catia，就获取当前的这个CATIA = GetObject(, "CATIA.Application")If Err.Number <> 0 Then' 如果没有打开catia，则打开新的catiaCATIA = CreateObject("CATIA.Application")CATIA.Visible = TrueEnd IfOn Error GoTo 0End SubEnd Module

添加宏库引用

catia自带的vba开发环境已经引用了很多库

需要在vb中引入import

vs开发环境初步

vs中的立即窗口

Imports MECMODModule Module1Public CATIA As INFITF.ApplicationPublic oPartDoc As PartDocumentSub Main()On Error Resume Next '有错误的话会忽略，继续执行下一句 ' 如果打开catia，就获取当前的这个CATIA = GetObject(, "CATIA.Application")If Err.Number <> 0 Then' 如果没有打开catia，则打开新的catiaCATIA = CreateObject("CATIA.Application")CATIA.Visible = TrueEnd IfOn Error GoTo 0oPartDoc = CATIA.ActiveDocumentMsgBox(oPartDoc.Name)End SubEnd Module

对象浏览器

Imports MECMODModule Module1Public CATIA As INFITF.ApplicationPublic oPartDoc As PartDocumentPublic oPart As PartPublic oBodies As BodiesPublic oBody As BodySub Main()On Error Resume Next '有错误的话会忽略，继续执行下一句 ' 如果打开catia，就获取当前的这个CATIA = GetObject(, "CATIA.Application")If Err.Number <> 0 Then' 如果没有打开catia，则打开新的catiaCATIA = CreateObject("CATIA.Application")CATIA.Visible = TrueEnd IfOn Error GoTo 0oPartDoc = CATIA.ActiveDocument'MsgBox(oPartDoc.Name)oPart = oPartDoc.PartoBodies = oPart.BodiesoBody = oBodies.Item(1)MsgBox(oBody.Name)End SubEnd Module

建立模板

可以把设置好库函数的引用的工程文件，作为一个标准的模板，后面直接复制这个标准模板，然后在这上面开发，就不需要每次都要创建各种引用了。

案例：创建一堆圆柱曲面

先创建一个宏库，用于保存接下来要录制的宏程序

第一步：录制宏

然后，工具，宏，启动录制，新建一个part，草图编辑，然后拉升，获得一个圆柱

编辑录制的宏

Sub CATMain()Dim documents1 As Documents
Set documents1 = CATIA.DocumentsDim partDocument1 As PartDocument
Set partDocument1 = documents1.Add("Part")Dim part1 As Part
Set part1 = partDocument1.PartDim bodies1 As Bodies
Set bodies1 = part1.BodiesDim body1 As Body
Set body1 = bodies1.Item("零件几何体")Dim sketches1 As Sketches
Set sketches1 = body1.SketchesDim originElements1 As OriginElements
Set originElements1 = part1.OriginElementsDim reference1 As Reference
Set reference1 = originElements1.PlaneXYDim sketch1 As Sketch
Set sketch1 = sketches1.Add(reference1)Dim arrayOfVariantOfDouble1(8)
arrayOfVariantOfDouble1(0) = 0#
arrayOfVariantOfDouble1(1) = 0#
arrayOfVariantOfDouble1(2) = 0#
arrayOfVariantOfDouble1(3) = 1#
arrayOfVariantOfDouble1(4) = 0#
arrayOfVariantOfDouble1(5) = 0#
arrayOfVariantOfDouble1(6) = 0#
arrayOfVariantOfDouble1(7) = 1#
arrayOfVariantOfDouble1(8) = 0#
Set sketch1Variant = sketch1
sketch1Variant.SetAbsoluteAxisData arrayOfVariantOfDouble1part1.InWorkObject = sketch1Dim factory2D1 As Factory2D
Set factory2D1 = sketch1.OpenEdition()Dim geometricElements1 As GeometricElements
Set geometricElements1 = sketch1.GeometricElementsDim axis2D1 As Axis2D
Set axis2D1 = geometricElements1.Item("绝对轴")Dim line2D1 As Line2D
Set line2D1 = axis2D1.GetItem("横向")line2D1.ReportName = 1Dim line2D2 As Line2D
Set line2D2 = axis2D1.GetItem("纵向")line2D2.ReportName = 2Dim circle2D1 As Circle2D
Set circle2D1 = factory2D1.CreateClosedCircle(0#, 0#, 25#)circle2D1.ReportName = 3Dim constraints1 As Constraints
Set constraints1 = sketch1.ConstraintsDim reference2 As Reference
Set reference2 = part1.CreateReferenceFromObject(circle2D1)Dim constraint1 As Constraint
Set constraint1 = constraints1.AddMonoEltCst(catCstTypeRadius, reference2)constraint1.Mode = catCstModeDrivingDimensionDim length1 As Length
Set length1 = constraint1.Dimensionlength1.Value = 25#sketch1.CloseEditionpart1.InWorkObject = sketch1part1.UpdateObject sketch1Dim hybridShapeFactory1 As HybridShapeFactory
Set hybridShapeFactory1 = part1.HybridShapeFactoryDim hybridShapeDirection1 As HybridShapeDirection
Set hybridShapeDirection1 = hybridShapeFactory1.AddNewDirectionByCoord(0#, 0#, 0#)Dim reference3 As Reference
Set reference3 = part1.CreateReferenceFromObject(sketch1)Dim hybridShapeExtrude1 As HybridShapeExtrude
Set hybridShapeExtrude1 = hybridShapeFactory1.AddNewExtrude(reference3, 20#, 0#, hybridShapeDirection1)hybridShapeExtrude1.SymmetricalExtension = 0body1.InsertHybridShape hybridShapeExtrude1part1.InWorkObject = hybridShapeExtrude1part1.UpdateEnd Sub

第二步：代码精简

代码精简

Sub CATMain()Set documents1 = CATIA.Documents
Set partDocument1 = documents1.Add("Part")
Set part1 = partDocument1.Part
Set bodies1 = part1.Bodies
Set body1 = bodies1.Item("零件几何体")
Set sketches1 = body1.Sketches
Set originElements1 = part1.OriginElements
Set reference1 = originElements1.PlaneXY
Set sketch1 = sketches1.Add(reference1)Set factory2D1 = sketch1.OpenEdition()
Set circle2D1 = factory2D1.CreateClosedCircle(0#, 0#, 5#)
Set constraints1 = sketch1.Constraints
Set reference2 = part1.CreateReferenceFromObject(circle2D1)
Set constraint1 = constraints1.AddMonoEltCst(catCstTypeRadius, reference2)Set length1 = constraint1.Dimension
length1.Value = 5#
sketch1.CloseEdition
part1.InWorkObject = sketch1
part1.UpdateSet hybridShapeFactory1 = part1.HybridShapeFactory
Set hybridShapeDirection1 = hybridShapeFactory1.AddNewDirectionByCoord(0#, 0#, 0#)
Set reference3 = part1.CreateReferenceFromObject(sketch1)
Set hybridShapeExtrude1 = hybridShapeFactory1.AddNewExtrude(reference3, 20#, 0#, hybridShapeDirection1)
'hybridShapeExtrude1.SymmetricalExtension = 0body1.InsertHybridShape hybridShapeExtrude1
part1.InWorkObject = hybridShapeExtrude1  '需要加上，不然不会自动更新
part1.UpdateEnd Sub

第三步：for循环改造

for循环改造

Sub CATMain()Set documents1 = CATIA.Documents
Set partDocument1 = documents1.Add("Part")
Set part1 = partDocument1.Part
Set bodies1 = part1.Bodies
Set body1 = bodies1.Item("零件几何体")X = 0
For i = 1 To 5Set sketches1 = body1.Sketches
Set originElements1 = part1.OriginElements
Set reference1 = originElements1.PlaneXY
Set sketch1 = sketches1.Add(reference1)
Set factory2D1 = sketch1.OpenEdition()Set circle2D1 = factory2D1.CreateClosedCircle(X, 0#, 5#)Set constraints1 = sketch1.Constraints
Set reference2 = part1.CreateReferenceFromObject(circle2D1)
Set constraint1 = constraints1.AddMonoEltCst(catCstTypeRadius, reference2)Set length1 = constraint1.Dimension
length1.Value = 5#
sketch1.CloseEdition
part1.InWorkObject = sketch1
part1.UpdateSet hybridShapeFactory1 = part1.HybridShapeFactory
Set hybridShapeDirection1 = hybridShapeFactory1.AddNewDirectionByCoord(0#, 0#, 0#)
Set reference3 = part1.CreateReferenceFromObject(sketch1)
Set hybridShapeExtrude1 = hybridShapeFactory1.AddNewExtrude(reference3, 20#, 0#, hybridShapeDirection1)
'hybridShapeExtrude1.SymmetricalExtension = 0body1.InsertHybridShape hybridShapeExtrude1
part1.InWorkObject = hybridShapeExtrude1  '需要加上，不然不会自动更新
part1.UpdateX = X + 20
Next
part1.UpdateEnd Sub

第四步：人机交互改造

顶部对齐

Private Sub CommandButton1_Click()Set documents1 = CATIA.Documents
Set partDocument1 = documents1.Add("Part")
Set part1 = partDocument1.Part
Set bodies1 = part1.Bodies
Set body1 = bodies1.Item("零件几何体")X = 0
For i = 1 To TextBox1.ValueSet sketches1 = body1.Sketches
Set originElements1 = part1.OriginElements
Set reference1 = originElements1.PlaneXY
Set sketch1 = sketches1.Add(reference1)
Set factory2D1 = sketch1.OpenEdition()Set circle2D1 = factory2D1.CreateClosedCircle(X, 0#, 5#)Set constraints1 = sketch1.Constraints
Set reference2 = part1.CreateReferenceFromObject(circle2D1)
Set constraint1 = constraints1.AddMonoEltCst(catCstTypeRadius, reference2)Set length1 = constraint1.Dimension
length1.Value = 5#
sketch1.CloseEdition
part1.InWorkObject = sketch1
part1.UpdateSet hybridShapeFactory1 = part1.HybridShapeFactory
Set hybridShapeDirection1 = hybridShapeFactory1.AddNewDirectionByCoord(0#, 0#, 0#)
Set reference3 = part1.CreateReferenceFromObject(sketch1)
Set hybridShapeExtrude1 = hybridShapeFactory1.AddNewExtrude(reference3, 20#, 0#, hybridShapeDirection1)
'hybridShapeExtrude1.SymmetricalExtension = 0body1.InsertHybridShape hybridShapeExtrude1
part1.InWorkObject = hybridShapeExtrude1  '需要加上，不然不会自动更新
part1.UpdateX = X + TextBox2.Value
Next
part1.UpdateEnd Sub

窗口模态设置

导出窗口fm

这里本来想导出vba中创建的窗口，然后在vb.net中导入，直接使用，但是两个版本的vb差别较大，并没有成功

添加现有项失败，可能是版本的问题，毕竟vb是很老的，我这里用的是vs

第五步：搭建vs的开发环境

Imports MECMOD
Imports PARTITF
Imports HybridShapeTypeLibModule Module1Public CATIA As INFITF.ApplicationPublic oPartDoc As PartDocumentPublic oPart As PartPublic oBodies As BodiesPublic oBody As BodyPublic oHBodies As HybridBodiesPublic oHBody As HybridBodyPublic oSF As ShapeFactoryPublic oHSF As HybridShapeFactory' ***********************************************************************'   目的：      初始化CATIA产品文档，并初始化必要的基本变量''   输入：      bNewProduct:   初始化时是否新建产品文件'                              可选，默认新建文件'               strProduct:    初始化时是否打开已经存在的产品文件'                              可选，默认新建文件' ***********************************************************************Sub InitCATIAPart(Optional ByVal bNewPart As Boolean = True,Optional ByVal strPart As String = "")On Error Resume Next '有错误的话会忽略，继续执行下一句 ' 如果打开catia，就获取当前的这个CATIA = GetObject(, "CATIA.Application")If Err.Number <> 0 Then' 如果没有打开catia，则打开新的catiaCATIA = CreateObject("CATIA.Application")CATIA.Visible = TrueEnd IfIf bNewPart ThenoPartDoc = CATIA.Documents.Add("Part")ElseIf strPart = "" ThenoPartDoc = CATIA.ActiveDocumentIf oPartDoc Is Nothing ThenErr.Clear()oPartDoc = CATIA.Documents.Add("Part")End IfElseIf Dir(strPart) <> "" ThenoPartDoc = CATIA.Documents.Open(strPart)ElseMsgBox("指定的文件不存在！")EndEnd IfEnd IfEnd IfOn Error GoTo 0oPartDoc = CATIA.ActiveDocumentoPart = oPartDoc.PartoBodies = oPart.BodiesoBody = oBodies.Item(1)oHBodies = oPart.HybridBodiesoHBody = oHBodies.Add()oSF = oPart.ShapeFactoryoHSF = oPart.HybridShapeFactoryEnd Sub
End Module

窗口布局设置

第六步：改造录制的宏

Imports MECMOD
Imports HybridShapeTypeLib
Imports INFITFPublic Class Form1Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.ClickInitCATIAPart(True) 'true表示新建一个partDim XDis As Integer = 0For iCount = 1 To Val(TextBox1.Text)Dim sketches1 As Sketches = oBody.SketchesDim originElements1 As OriginElements = oPart.OriginElementsDim reference1 As Reference = originElements1.PlaneXYDim sketch1 As Sketch = sketches1.Add(reference1)Dim factory2D1 As Factory2D = sketch1.OpenEdition()Dim circle2D1 As Circle2D = factory2D1.CreateClosedCircle(XDis, 0#, 5.0#)Dim constraints1 As Constraints = sketch1.ConstraintsDim reference2 As Reference = oPart.CreateReferenceFromObject(circle2D1)Dim constraint1 = constraints1.AddMonoEltCst(CatConstraintType.catCstTypeRadius, reference2)Dim length1 = constraint1.Dimensionlength1.Value = 5.0#sketch1.CloseEdition()oPart.InWorkObject = sketch1oPart.Update()Dim hybridShapeDirection1 As HybridShapeDirection = oHSF.AddNewDirectionByCoord(0#, 0#, 0#)Dim reference3 As Reference = oPart.CreateReferenceFromObject(sketch1)Dim hybridShapeExtrude1 = oHSF.AddNewExtrude(reference3, 20.0#, 0#, hybridShapeDirection1)'hybridShapeExtrude1.SymmetricalExtension = 0oBody.InsertHybridShape(hybridShapeExtrude1)oPart.InWorkObject = hybridShapeExtrude1  '需要加上，不然不会自动更新oPart.Update()XDis = XDis + Val(TextBox2.Text)NextoPart.Update()End Sub
End Class

第七步：进行测试

报错：关于非窗体转换成窗体报错Model1中找不到sub main

启动成功
