C# SolidWorks 二次开发 API—遍历草图

代码:

这里示意获取草图中线段的总长:

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

            ModelDoc2 swModel = default(ModelDoc2);
            ModelDocExtension swModelDocExt = default(ModelDocExtension);
            SelectionMgr swSelMgr = default(SelectionMgr);
            Feature swFeature = default(Feature);
            string fileName = null;
            bool status = false;
            int errors = 0;
            int warnings = 0;

            //打开文件
            fileName = "C:\\Users\\Public\\Documents\\SOLIDWORKS\\SOLIDWORKS 2018\\samples\\tutorial\\tolanalyst\\offset\\top_plate.sldprt";
            swModel = (ModelDoc2)swApp.OpenDoc6(fileName, (int)swDocumentTypes_e.swDocPART, (int)swOpenDocOptions_e.swOpenDocOptions_Silent, "", ref errors, ref warnings);

            swModelDocExt = (ModelDocExtension)swModel.Extension;

            //选中草图
            status = swModelDocExt.SelectByID2("Sketch1", "SKETCH", 0, 0, 0, false, 0, null, 0);

            swSelMgr = (SelectionMgr)swModel.SelectionManager;
            //转换
            swFeature = (Feature)swSelMgr.GetSelectedObject6(1, -1);
            //进入编辑草图
            swModel.EditSketch();
            //获取草图中的所有线
            object[] vSketchSeg = (object[])swFeature.GetSpecificFeature2().GetSketchSegments();

            SketchSegment swSketchSeg;
            double totalLenth = 0;
            foreach (var tempSeg in vSketchSeg)
            {
                swSketchSeg = (SketchSegment)tempSeg;
                //这里判断 不是文本,并且不是中心线 则加入长度
                if (swSketchSeg.GetType() != (int)swSketchSegments_e.swSketchTEXT && swSketchSeg.ConstructionGeometry == false)
                {
                    totalLenth = totalLenth + swSketchSeg.GetLength();
                }
            }

            swModel.EditSketch();
            //显示总长
            swApp.SendMsgToUser("Total Length:" + totalLenth * 1000);
        }
