C# SolidWorks 二次开发 API — 高级选择器

Solidworks在装配体中提供了一项高级选择的功能.

这个功能可以很快的选择我们想要选择的一些零件.尤其是比较大的装配体,效率比遍历装配体之后 再通过程序过滤来选择想要的零件快.

 

上代码:

  #region 高级选择

        private void btn_Adv_Select_Click(object sender, EventArgs e)
        {
            //请先打开C:\Users\Public\Documents\SOLIDWORKS\SOLIDWORKS 2018\samples\tutorial\api\landing_gear.sldasm

            //参考资料为API 帮助中的 Use Advanced Component Selection Example (C#)

            ISldWorks swApp = Utility.ConnectToSolidWorks();
            ModelDoc2 swModel = default(ModelDoc2);

            swModel = swApp.ActiveDoc;

            int DocType = 0;
            DocType = swModel.GetType();

            if (DocType != (int)swDocumentTypes_e.swDocASSEMBLY)
            {
                swApp.SendMsgToUser("当前不是装配体!");
                return;
            }

            AdvancedSelectionCriteria advancedSelectionCriteria = default(AdvancedSelectionCriteria);

            AssemblyDoc assemblyDoc = (AssemblyDoc)swModel;

            advancedSelectionCriteria = assemblyDoc.GetAdvancedSelection();

            int count = advancedSelectionCriteria.GetItemCount();

            //清空选择条件
            for (int i = 0; i < advancedSelectionCriteria.GetItemCount(); i++)
            {
                advancedSelectionCriteria.DeleteItem(i);
            }

            //增加选择条件 : 文件名包含lnk
            advancedSelectionCriteria.AddItem("Document name -- SW Special", 16, "lnk", false);
            //增加选择条件(或者) : 文件名包含hub
            advancedSelectionCriteria.AddItem("Document name -- SW Special", 16, "hub", false);

            //解释当前的选择条件
            ReportAllValues(advancedSelectionCriteria);

            //选择

C# SolidWorks 二次开发 API—提示信息与进度条

有些情况 我们需要像solidworks的内部命令一样提示用户现在该做什么,或者说要显示一下当前进度.

第一种方法就是自己设计一个界面,上面放进度条,这种可以弄成自己想要的样式,但是我们今天要说的是自带的方法:

win10下进度条是在系统任务栏中显示,win7应该是在solidworks的状态栏中.

 

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

            ModelDoc2 swModel = default(ModelDoc2);
            ModelDocExtension swModelDocExt = default(ModelDocExtension);

            Frame swFrame = swApp.Frame();

            swFrame.SetStatusBarText("这里是提示信息-->");

            swApp.SendMsgToUser("下面提示显示进度条:");

            UserProgressBar userProgressBar;

            swApp.GetUserProgressBar(out userProgressBar);

            userProgressBar.Start(0, 100, "Status");

            int Position = 0;

            for (int i = 0; i <= 100; i++)
            {
                Position = i * 10;

                if (Position == 100)
                {
                    Position = 0;
                    break;
                }

                var lRet = userProgressBar.UpdateProgress(Position);
                userProgressBar.UpdateTitle("当前进度--->" + Position);

                swApp.SendMsgToUser("当前进度--->" + Position);
            }

            userProgressBar.End();
        }

C# SolidWorks 二次开发 API—增加第三方数据流

今天增加了如何保存文件的第三数据流到solidworks的文件中.

例如xml文件,文本信息.

 private ModelDoc2 m_RefDoc; //增加第三方数据流 共用模型.

        private void btn_ThridData_Click(object sender, EventArgs e)
        {
            //https://www.codestack.net/solidworks-api/data-storage/third-party/embed-file/
            ISldWorks swApp = Utility.ConnectToSolidWorks();

            ModelDoc2 swModel = default(ModelDoc2);
            ModelDocExtension swModelDocExt = default(ModelDocExtension);

            swModel = swApp.ActiveDoc;
            m_RefDoc = swModel;

                    break;
            }

            swModel.SetSaveFlag();

C# SolidWorks 二次开发 API—如何通过面属性命名选中对象

今天有人问到如何选中零件中已经命名的面.那我们就先把这个记录一下.

比如,零件中我们命名了一个面的名称

有两种情况:

1,零件中选中该面:

             ISldWorks swApp = Utility.ConnectToSolidWorks();
            ModelDoc2 swModel = swApp.ActiveDoc;
            SelectionMgr swSelMgr = swModel.SelectionManager;          
             PartDoc part1 = (PartDoc)swModel;
            //在零件中选择
            Face2 face1 = part1.GetEntityByName("SFace1", (int)swSelectType_e.swSelFACES);
            Entity entity1 = (Entity)face1;
            entity1.Select(false);

 

 

2.装配中:

 #region 装配中选择

            //这里我们默认该零件已经是选中装配,否则我们需要遍历一次零件,仅做示例

            Component2 component = swSelMgr.GetSelectedObjectsComponent4(1, -1);

            swModel.ClearSelection();

            ModelDoc2 modelDoc = component.GetModelDoc2();

            //转换为PartDoc
            PartDoc part = (PartDoc)modelDoc;

            Face2 face = part.GetEntityByName("SFace1", (int)swSelectType_e.swSelFACES);

            Entity entity = (Entity)face;

            //在装配中再转换成装配中的实体
            Entity entityInComp = (Entity)component.GetCorrespondingEntity(entity);

            entityInComp.Select(false);

            #endregion

C# SolidWorks 二次开发 API—删除草图中的约束关系

这一个比较简单,其实就是遍历一下草图中的对象,然后获取关系,删除.

代码:

 private void btn_DeleteConstraints_Click(object sender, EventArgs e)
        {
            //请先打开clamp1这个零件

            ISldWorks swApp = Utility.ConnectToSolidWorks();
            ModelDoc2 swModel = swApp.ActiveDoc;
            SelectionMgr swSelMgr = swModel.SelectionManager;

            //选择草图
            swModel.Extension.SelectByID2("Sketch2", "SKETCH", 0, 0, 0, false, 4, null, 0);

            //进入编辑草图
            swModel.EditSketch();

            //获取当前草图对象
            Sketch swSketch = swModel.GetActiveSketch2();

            //获取该草图中的所有线
            object[] vSketchSeg = swSketch.GetSketchSegments();

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

            SketchSegment swSketchSeg;
            //遍历线
            for (int i = 0; i < vSketchSeg.Length; i++)
            {
                swSketchSeg = (SketchSegment)vSketchSeg[i];
                swSketchSeg.Select4(false, swSelData);
                //删除关系
                swModel.SketchConstraintsDelAll();
            }


            object[] vSketchPt = (SketchPoint[])swSketch.GetSketchPoints2();
            SketchPoint swSketchPt;
            //遍历点
            for (int i = 0; i < vSketchPt.Length; i++)
            {
                swSketchPt = (SketchPoint)vSketchPt[i];
                swSketchPt.Select4(false, swSelData);
                swModel.SketchConstraintsDelAll();
            }
            //退出编辑草图
            swModel.InsertSketch2(true);

            swModel.ClearSelection2(true);
        }
