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);
        }
