问题描述

我试图使一个三维CAD程序Solid Edge的一个Visual Basic控制台应用程序,在我想的Visual Basic,使曲线它这个控制台应用程序。欲与第四度方程。用于方程的数据存储在一个空间dilimited文本文件,使这些曲线。在文本文件中,有不同的数据多行,每行用于使第四度方程。现在,我试图让该程序,但它卡住了在做曲线线条,控制台只是停留黑,不会关闭。该方案确实对程序的连接,并打开了3D建模环境。

有谁知道我在做什么错在我的code,或者我应该怎么办呢?我使用的Visual Basic 2003非标准。我不是一个程序员,但我尝试这种自动化的东西,在3D CAD程序。

这是我的code:

解决方案

我要猜你应该移动的code此块是你的循环,即外界。在做的,而objSR.Peek<> -1 。在循环会做所有这些事情在你的文件的每一行。我想你只会想这样做的东西一次。

 连接到Solid Edge的文件。
        '连接到的Solid Edge的运行实例
        objApp = Marshal.GetActiveObject(SolidEdge.Application)
        获取引用的文件集合
        objDocuments = objApp.Documents
        创建一个新的零件文档
        objPart = objDocuments.Add(SolidEdge.PartDocument)
        得到一个参考的资料设定集
        objProfileSets = objPart.ProfileSets
        添加新的配置文件集
        objProfileSet = objProfileSets.Add()
        获取引用轮廓集合
        objProfiles = objProfileSet.Profiles
        有了一个指向裁判飞机集合
        objRefplanes = objPart.RefPlanes
        打开一个新的草图
        objsketch = objPart.Sketches.Add
        添加新的配置文件
        objProfile = objProfiles.Add(objRefplanes.Item(3))
        Gat的一个参考样条曲线集合
        objBSplines = objProfile.BSplineCurves2d
        获取引用lines2d集合
        objLines2d = objProfile.Lines2d
 

然后,你可能会需要你的循环之后移动这,

 关闭个人资料
            objProfile.End(_
                SolidEdgePart.ProfileValidationType.igProfileClosed)
 

只是一个提示,您应该删除此行

 抓住EX为例外
 

如果你有一个空的块,你只会从自己隐藏任何错误。

I'm trying to make a visual basic console application for a 3D CAD program Solid Edge, in this console application I want visual basic to make curves in it. I want to make these curves with an 4th degree equation.The data used for the equation is stored in a space dilimited text file. In the text file there are several rows with different data, every row is used to make the 4th degree equation. Now, I tried to make the program but it got stuck at making the curve lines, the console just stays black and doesn't close. The program does make a connection to the program and opens up a 3d modeling environment.

Does anyone knows what I'm doing wrong in my code, or what I should do instead? I'm using visual basic 2003 standart.I'm not a programmer, but I try this to automate things in the 3D CAD program.

解决方案

I'm going to guess that you should move this block of code to be outside your loop, ie. before the Do While objSR.Peek <> -1. In the loop it will do all these things for each line in your file. I would think you would only want to do this stuff once.

      'connect to a Solid Edge file.
        ' Connect to a running instance of Solid Edge
        objApp = Marshal.GetActiveObject("SolidEdge.Application")
        ' Get a reference to the documents collection
        objDocuments = objApp.Documents
        ' Create a new part document
        objPart = objDocuments.Add("SolidEdge.PartDocument")
        ' Get a reference to the profile sets collection
        objProfileSets = objPart.ProfileSets
        ' Add a new profile set
        objProfileSet = objProfileSets.Add()
        ' Get a reference to the profiles collection
        objProfiles = objProfileSet.Profiles
        ' Get a reference to the ref planes collection
        objRefplanes = objPart.RefPlanes
        'open a new sketch
        objsketch = objPart.Sketches.Add
        ' Add a new profile
        objProfile = objProfiles.Add(objRefplanes.Item(3))
        'Gat a reference to spline curve collection
        objBSplines = objProfile.BSplineCurves2d
        ' Get a reference to the lines2d collection
        objLines2d = objProfile.Lines2d

Then you would probably have to move this to after your loop,

            ' Close the profile
            objProfile.End( _
                SolidEdgePart.ProfileValidationType.igProfileClosed)

Just a tip, you should remove this line

  Catch ex As Exception

If you have an empty catch block, you will just hide any errors from yourself.
