要想提高设计效率，做库特征是很常见的。例如我们下面这个视频，利用库特征在打了很多小孔。

利用库特征快速插入特征

这一次我们来看如何用代码插入库特征。

我们以API实例中的一个例子来说明一下过程：

        public DispatchWrapper[] ObjectArrayToDispatchWrapperArray(object[] Objects)
        {
            int ArraySize = 0;
            ArraySize = Objects.GetUpperBound(0);
            DispatchWrapper[] d = new DispatchWrapper[ArraySize + 1];
            int ArrayIndex = 0;
            for (ArrayIndex = 0; ArrayIndex <= ArraySize; ArrayIndex++)
            {
                d[ArrayIndex] = new DispatchWrapper(Objects[ArrayIndex]);
            }
            return d;
        }

        public DispatchWrapper[] LibRefs;

        private void btnInsertLibF_Click(object sender, EventArgs e)

当我们需要用户选择时,可以利用代码创建指定的选择器.

其实就像手工点击工具条内的过滤器一样:

 

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

            ModelDoc2 modelDoc2 = swApp.ActiveDoc;
            //SelectionMgr selectionMgr = modelDoc2.SelectionManager;

            //设置可选择类型的数组
            swSelectType_e[] filters = new swSelectType_e[1];

            //让用户只能选择实体

            filters[0] = swSelectType_e.swSelSOLIDBODIES;

            swApp.SetSelectionFilters(filters, true);
        }

 

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);
        }

                return true;
            }
        }

        public override bool CanWrite
        {
            get
            {
                return true;
            }
        }

                return true;
            }
        }
    }

 

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.

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();
        }
