C# SolidWorks 二次开发 API —工程图尺寸信息的读取

工程图尺寸信息的读取

前提条件： 在打开的工程图选中一个尺寸
本文目标： 通过转换选择的尺寸为一个尺寸对象，获取该尺寸的值与公差。

 private void btnGetDimensionInfo_Click(object sender, EventArgs e)
        {
            ISldWorks swApp = Utility.ConnectToSolidWorks();
            swApp.CommandInProgress = true;

            ModelDoc2 swModel = (ModelDoc2)swApp.ActiveDoc;

            SelectionMgr selectionMgr = (SelectionMgr)swModel.SelectionManager;

            //转换成尺寸显示对象
            var swDisplayDimension = (DisplayDimension)selectionMgr.GetSelectedObject6(1, 0);

            DisplayData displayData = (DisplayData)swDisplayDimension.GetDisplayData();

            //获取尺寸上的文字
            var anno = (Annotation)swDisplayDimension.GetAnnotation();

            //获取所在视图 ---如果是图纸，这里会报错。需要用OwnerType来判断
            var thisView = (View)anno.Owner;//

            var textwidth = displayData.GetTextInBoxWidthAtIndex(0);

            var textHeight = displayData.GetTextHeightAtIndex(0);

            // dat.GetLineCount 几条线
            var lineCount = displayData.GetLineCount();
            var lineAngle = displayData.GetTextAngleAtIndex(0);
            var linePoints = (double[])displayData.GetLineAtIndex(0);
            var linePoints2 = (double[])displayData.GetLineAtIndex(1);
            var textPoint = (double[])displayData.GetTextPositionAtIndex(0);

            var thisDimAng = lineAngle * 180 / Math.PI;

            //尺寸对象
            var swDimension = (Dimension)swDisplayDimension.GetDimension();

            //获取尺寸的公差
            var cruToleranceType = swDimension.GetToleranceType();
            var cruTolerance = swDimension.Tolerance;

            if (cruToleranceType == (int)swTolType_e.swTolBILAT)
            {
                cruTolerance.GetMaxValue2(out double ToleranceValueMax); //上公差

                cruTolerance.GetMinValue2(out double ToleranceValueMin);//下公差
            }

            var TextAll = swDisplayDimension.GetText((int)swDimensionTextParts_e.swDimensionTextAll);
            var TextPrefix = swDisplayDimension.GetText((int)swDimensionTextParts_e.swDimensionTextPrefix);
            var TextSuffix = swDisplayDimension.GetText((int)swDimensionTextParts_e.swDimensionTextSuffix);
            var CalloutAbove = swDisplayDimension.GetText((int)swDimensionTextParts_e.swDimensionTextCalloutAbove);
            var CalloutBelow = swDisplayDimension.GetText((int)swDimensionTextParts_e.swDimensionTextCalloutBelow);

            var relValue = Math.Round(swDimension.GetSystemValue2("") * 1000, 3).ToString();

            MessageBox.Show(relValue);
        }

上面是代码，有一些备注。

这是初学markdown写的， 源代码继续在码云或者github上拿。

C# SolidWorks 二次开发 API —Solidworks的多开操作与连接指定版本Solidworks

        今天有网友问我关于如何用Exe操作多个Solidworks的问题，其实之前我看到过解决方案，是通过进程和id获取，而不是我们平时常用的 (SldWorks)Marshal.GetActiveObject(“SldWorks.Application.27”);

        所以晚上回来查了些资料，发现了有了解决方案，我精简了一下，做了个dll.大家可以试试。    

 ''' <summary>
    ''' 创建一个新的Solidworks并返回实例
    ''' </summary>
    ''' <param name="version">指定版本号，-1表示默认.</param>
    ''' <param name="suppressDialogs">True 则禁用solidworks弹出消息.</param>
    ''' <param name="requireMainWindow">True 表示运行完显示到主窗口</param>
    ''' <param name="startProcessTimeout">返回Null 如果SolidWorks在指定时间内没有打开。</param>
    ''' <param name="createWindowTimeout">返回Null 如果SolidWorks主窗口在指定时间内没有显示.</param>
    ''' <returns></returns>
    Public Shared Function RunSolidWorks(version As Integer,
                                         visible As Boolean,
                                         Optional suppressDialogs As Boolean = False,
                                         Optional requireMainWindow As Boolean = True,
                                         Optional startProcessTimeout As Integer = 30,
                                         Optional createWindowTimeout As Integer = 15) As SldWorks

        Dim executablePath As String = CTFileSystem.GetSolidWorksExecutablePath(version)

        If File.Exists(executablePath) = False Then Return Nothing

        Dim info As ProcessStartInfo = New ProcessStartInfo(executablePath)

        If suppressDialogs Then info.Arguments = "/r"

        Dim process As Process = Process.Start(info)
        Dim app As SldWorks = Nothing
        Dim t As DateTime = DateTime.Now

        While app Is Nothing
            Threading.Thread.Sleep(1000)
            If Math.Abs(DateTime.Now.Subtract(t).Seconds) > startProcessTimeout Then Return Nothing

            'If it were possible to get a GUID from a process ID then we could use GetActiveObject instead of this
            app = GetComObjectFromProcessId(process.Id)
        End While

        t = DateTime.Now
        While IsRunning(isMainWindowCreated:=True) = False
            Threading.Thread.Sleep(1000)
            If Math.Abs(DateTime.Now.Subtract(t).Seconds) > createWindowTimeout Then Return Nothing
        End While

        If visible = False Then
            Dim frame As Frame = app.Frame()
            If frame Is Nothing Then Return app
            Dim handle As IntPtr = frame.GetHWndx64()
            If ShowWindow(handle, 0) Then Return app
        End If

        Return app
    End Function

我刚刚进行了测试，用起来比较简单。我用代码新建了两个solidworks 2018窗口：

        private SldWorks sldWorks2018_1 = null;
        private SldWorks sldWorks2018_2 = null;

        private void button1_Click(object sender, EventArgs e)
        {
            sldWorks2018_1 = PStandAlone.RunSolidWorks(26, true, false, false, 30, 15);
        }

        private void button2_Click(object sender, EventArgs e)
        {
            sldWorks2018_2 = PStandAlone.RunSolidWorks(26, true, false, false, 30, 15);
        }

        private void button3_Click(object sender, EventArgs e)
        {
            sldWorks2018_1.SendMsgToUser("From 2018 -1");
            sldWorks2018_2.SendMsgToUser("From 2018 -2");
        }

C# SolidWorks 二次开发 API—钣金零件信息提取

有一段时间没有发博文了，最近有人问到钣金件的相关操作，今天我们来看看钣金零件信息的读取。

Solidworks中钣金件是有一个单独的模块，里面有一些固定的文件夹结构。

最后这个文件夹中包含了展开状态时零件的信息。如长度与折弯线相关的信息都在这里面。

一般我们要找到长 宽 厚 折弯角 与距离  折弯方向 这些信息。

输出结果如下，有些小数的处理就忽略了。大家看看就行。 

粗略的写了下，输入信息在这里。很多就是API帮助里面的例子，大家可以在中文翻译中查找到。

        private void btnSheetmetal_Click(object sender, EventArgs e)
        {
            //连接到Solidworks
            ISldWorks swApp = Utility.ConnectToSolidWorks();
            swApp.CommandInProgress = true;
            ModelDoc2 swModel = (ModelDoc2)swApp.ActiveDoc;

            //钣金 变成平板模式的特征
            List<Feature> flatPatternFeatures = new List<Feature>();

            //Bounding Box草图
            List<string> boundingSketchesName = new List<string>();

            //获取当前钣金状态--这个已经过时

            //swSMBendStateFlattened  2 = 弯曲变平；该模型回滚到FlattenBends功能之后，但恰好在相应的ProcessBends功能之前
            //swSMBendStateFolded 3 = 折弯处已折叠；模型回滚到FlattenBends ProcessBends功能对之后
            //swSMBendStateNone   0 = 不是钣金零件；没有SheetMetal功能
            //swSMBendStateSharps 1 = 弯曲处处于锐利状态；零件回滚到第一个FlattenBends功能之前

            var bendState = swModel.GetBendState();

            if (bendState == 0)
            {
                swApp.SendMsgToUser("不是钣金零件！");
                return;
            }
            //  swApp.SendMsgToUser("当前状态" + bendState);
            if (bendState != 2)
            {
                //swApp.Command((int)swCommands_e.swCommands_Flatten, "");
                //设定当前钣金状态 平板 ，下面这行代码不适用现在的零件 ，只适用于很早之前的零件
                //var setStatus = swModel.SetBendState((int)swSMBendState_e.swSMBendStateFlattened);

                //新钣金均是通过获取零件
                var swFeatureManager = swModel.FeatureManager;
                var flatPatternFolder = (FlatPatternFolder)swFeatureManager.GetFlatPatternFolder();

                var featArray = (object[])flatPatternFolder.GetFlatPatterns();

                for (int i = featArray.GetLowerBound(0); i <= featArray.GetUpperBound(0); i++)
                {
                    var feat = (Feature)featArray[i];
                    Debug.Print("    " + feat.Name);

                    flatPatternFeatures.Add(feat);

C# SolidWorks 二次开发 API —如何修改草图里面的直线

 昨天有网友想知道怎么修改草图的内容，今天来带着找一找如何解决。

在之前打开和创建那个命令里面我写过如下代码 ：

                    //选择对应的草图基准面
                    bool boolstatus = swModel.Extension.SelectByID2("Plane1", "PLANE", 0, 0, 0, false, 0, null, 0);

                    //创建一个2d草图
                    swModel.SketchManager.InsertSketch(true);

                    //画一条线 长度100mm  (solidworks 中系统单位是米,所以这里写0.1)
                    swModel.SketchManager.CreateLine(0, 0, 0, 0, 0.1, 0);

                    //关闭草图
                    swModel.SketchManager.InsertSketch(true);

这里面知道了草图管理器是SketchManager.

我们去API帮助里面查找SketchManager.很容易就能找到这里有个官方示例。

 

这里虽然是VBA的，但是可以大概知道大体步骤，参考这个就能知道如何读取这些信息了，可以先把这个例子弄懂。再来考虑怎么修改，我也就写几行简单的代码，把之前 我在图中画的一条直线长度 和位置修改掉。

默认当前状态：

代码如下：

        private void btnCreateSketch_Click(object sender, EventArgs e)
        {
            //如果没有打开文件，请执行打开和创建的操作：
            //BtnOpenAndNew_Click(null, null);

            //连接到Solidworks
            ISldWorks swApp = Utility.ConnectToSolidWorks();

            ModelDoc2 swModel = (ModelDoc2)swApp.ActiveDoc;

            //定义草图管理器
            SketchManager sketchManager = swModel.SketchManager;

            //按名字选择草图
            bool boolstatus = swModel.Extension.SelectByID2("Sketch1", "SKETCH", 0, 0, 0, false, 0, null, 0);

            if (boolstatus == true)
            {
                //编辑草图
                sketchManager.InsertSketch(false);
                //获取当前草图，当获取草图中的Segment对象
                Sketch sketch = swModel.GetActiveSketch2();
                object[] sketchSegments = sketch.GetSketchSegments();

                if (sketchSegments != null)
                {
                    //遍历
                    foreach (var skSeg in sketchSegments)
                    {
                        SketchSegment sketchSegment = (SketchSegment)skSeg;

                        //判断是直线时执行
                        if (sketchSegment.GetType() == (int)swSketchSegments_e.swSketchLINE)
                        {
                            SketchLine sketchLine = (SketchLine)sketchSegment;
                            SketchPoint sketchPointStart = sketchLine.GetStartPoint2();
                            SketchPoint sketchPointEnd = sketchLine.GetEndPoint2();

                            //这里显示弹出坐标，单位默认是米
                            MessageBox.Show(sketchPointStart.X.ToString() + "," + sketchPointStart.Y.ToString());
                            MessageBox.Show(sketchPointEnd.X.ToString() + "," + sketchPointEnd.Y.ToString());

                            SelectionMgr swSelMgr = swModel.SelectionManager;

                            //定义选择数据
                            SelectData swSelData = swSelMgr.CreateSelectData();

                            //选择此直线

                            sketchSegment.Select4(false, swSelData);

                            //删除当前的约束关系
                            swModel.SketchConstraintsDelAll();

                            //下在我们来修改坐标
                            sketchPointStart.X = 0.05;
                            sketchPointStart.Y = 0.04;

                            sketchPointEnd.X = 0.2;
                            sketchPointEnd.Y = 0.2;
                        }
                    }
                }

                //退出草图
                sketchManager.InsertSketch(true);
            }
        }

执行过后，文件中的草图变成了：

这里讲解的就是一个思路，大家应该能看明白吧。

具体的代码可以去我的码云或者github下载，欢迎大家提问。

C# SolidWorks 二次开发 API — 提升exe执行效率接近DLL

          最近一段时间没更新博客，原因比较多。作为湖北人，今年的班上的不容易。当然还是要感谢各地的支援。

          今天来和大家分享一下一个关于exe提升性能的选项，因为之前主要写的exe比较多，后来改成dll之后效率提升很大，但是最近发现了一个新大陆，在exe中大量读取solidworks文件的数据时，可以先通过swApp.CommandInProgress这个设置为True 来提高性能。

           先看下API帮助中的定义：

           大概意思要是先告诉SOLIDWORKS准备在进程外将进行一系列API调用，提高了进程外应用程序的性能。

         经过测试，在做一些大量读取数据的时候，性能相对于没有设定之前提高了近4倍，结果和dll的差距已经不太大了，因为DLL里面调试没有exe方便，这样设定之后可以减少调试所需的时间，提高运行效率。

本地时间测试

Type	Time
exe with CommandInProgress = Ture	111s
exe with CommandInProgress = False	460s
DLL	78s

C# SolidWorks 二次开发 API — 修改全局变量的值

今天来简单讲一下如何修改方程式中的一些数据,有时候一些简单的模型我们就可以利用这个全局变量来控制模型.

如下图: 我设定了零件的高度方程式与全局变量h相等.

等到我们需要更新高度时,就可以直接修改这个全局变量,做到更简单的参数化方式,这个全局变量可以是上级装配体中的信息.

 下面来具体演示下如何找api:

打开api帮助文件,搜索关键字 globalvariable,就会发现右侧的实例,是一个获取信息的.

This example shows how to get the values of equations.

//-----------------------------------------
// Preconditions:
// 1. Open public_documents\samples\tutorial\api\partequations.sldprt.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Gets each equation's value and index and whether the 
//    equation is a global variable. 
// 2. Examine the Immediate window.
//------------------------------------------
using SolidWorks.Interop.sldworks;
using SolidWorks.Interop.swconst;
using System.Runtime.InteropServices;
using System;
using System.Diagnostics;
 
namespace Macro1CSharp.csproj
{
    public partial class SolidWorksMacro
    {
        public void Main()
        {
            ModelDoc2 swModel = default(ModelDoc2);
            EquationMgr swEqnMgr = default(EquationMgr);
            int i = 0;
            int nCount = 0;
 
            swModel = (ModelDoc2)swApp.ActiveDoc;
            swEqnMgr = (EquationMgr)swModel.GetEquationMgr();
            Debug.Print("File = " + swModel.GetPathName());
            nCount = swEqnMgr.GetCount();
            for (i = 0; i < nCount; i++)
            {
                Debug.Print("  Equation(" + i + ")  = " + swEqnMgr.get_Equation(i));
                Debug.Print("    Value = " + swEqnMgr.get_Value(i));
                Debug.Print("    Index = " + swEqnMgr.Status);
                Debug.Print("    Global variable? " + swEqnMgr.get_GlobalVariable(i));
            }
 
        }
 
        /// <summary>
        ///  The SldWorks swApp variable is pre-assigned for you.
        /// </summary>
        public SldWorks swApp;
    }
}

我们参考这段代码来完成方程式信息的读取: 增加按钮写代码.

 参照帮助文件写完的版本大概为:

运行一下:

 

下面我们来做修改:

private void butGlobalVariables_Click(object sender, EventArgs e)
        {
            //连接solidworks
            ISldWorks swApp = Utility.ConnectToSolidWorks();

            if (swApp != null)
            {
                //获取当前模型
                ModelDoc2 swModel = (ModelDoc2)swApp.ActiveDoc;
                //定义方程式管理器
                EquationMgr swEqnMgr = default(EquationMgr);

                int i = 0;
                int nCount = 0;

                if (swModel != null)
                {
                    swEqnMgr = (EquationMgr)swModel.GetEquationMgr();
                    // nCount = swEqnMgr.GetCount();
                    //for (i = 0; i < nCount; i++)
                    //{
                    //    Debug.Print("  Equation(" + i + ")  = " + swEqnMgr.get_Equation(i));
                    //    Debug.Print("    Value = " + swEqnMgr.get_Value(i));
                    //    Debug.Print("    Index = " + swEqnMgr.Status);
                    //    Debug.Print("    Global variable? " + swEqnMgr.get_GlobalVariable(i));
                    //}

                    //修改高度为60

                    if (SetEquationValue(swEqnMgr, "h", 60))
                    {
                        swModel.ForceRebuild3(true);
                    }
                    else
                    {
                        MessageBox.Show("没有找到这个值!");
                    }
                }
            }
        }

        #region 修改全局变量所用到的方法

        public bool SetEquationValue(EquationMgr eqMgr, string name, double newValue)
        {
            int index = GetEquationIndexByName(eqMgr, name);

            if (index != -1)
            {
                eqMgr.Equation[index] = "\"" + name + "\"=" + newValue;

                return true;
            }
            else
            {
                return false;
            }
        }

        //通过名字找方程式的位置
        private int GetEquationIndexByName(EquationMgr eqMgr, string name)
        {
            int i;
            for (i = 0; i <= eqMgr.GetCount() - 1; i++)
            {
                var eqName = eqMgr.Equation[i].Split('=')[0].Replace("=", "");

                eqName = eqName.Substring(1, eqName.Length - 2); // removing the "" symbols from the name

                if (eqName.ToUpper() == name.ToUpper())
                {
                    return i;
                }
            }

            return -1;
        }

        #endregion 修改全局变量所用到的方法

到此,零件高度变成了60, 这一节先讲这么多吧.

最终代码请到码云或者github上下载.
