C# SolidWorks 二次开发 API — 实例：自增文本标注

相信大家在工程图中难免需要手动标注一些东西，而且这些东西需要按顺序变化。

如有时候需要按如下顺序标注：A1 A2 A3 A4

我们公司常用的标法还有A1 B1 A2 B2 A3 B3 这种.

而Solidworks自动的标注只能默认与上一次写的内容一致，这样总是需要手动编辑，容易出错，还效率低。

 

1. 问题：如何快速的进行上述方式的标注.
2. 思路：捕获Solidworks中鼠标事件，在点击图纸的时候按设定好的方式进行标注。 这里面涉及到一些事件的委托，以及工程图里面一的些API,其次就是图纸和模型的一些处理。
3. 效果(之前做好的)： ~

 

   关键代码:

   这是之前做好的，所以没有做什么注释，有空会补上。

C# SolidWorks 二次开发 API — 实例：创建中心点位置

在实际生产需要中，有些情况 我们需要知道某个路径上整体的中心点，如水管，电阻丝这些，可能需要从路径的中点开始进行放置，这个实例我们来看如何进行中点的计算与标记。我们默认路径都是是直线和圆弧组成，均相切(辅助中心线不包含在路径长度内)。

1. ，问题：如何找到下面路径的中心点在哪里？进行标识，方便加工。

2，思路：

1. 先得到指定草图中的所有“线段”，把中心线排除掉之后，遍历并统计出它们的长度，从而得到总长L。并且还要得到一整串的“线段”顺序。可以考虑 链 相关的数据结构
2. 从起点或者终点开始，对每一段进行遍历，去找到中点所在的“线段”， 直到找到中点之后，通过“线段” 的参考进行计算。
3. 画出中点，或者能标识中点位置的辅助线。

3，代码：这里很久前写的，没有写什么注释，并且水平也很菜，估计很多人看不太懂。

C# SolidWorks 二次开发 API — 替换零件

有些情况下我们需要去零件进行升级改版，需要先改好零件再利用替换功能进行升级。

今天简单介绍下如何在装配体中进行零件的替换，当然我们默认参考关系都没问题。

 

代码如下：

private void Btn_ReplacePart_Click(object sender, EventArgs e)
        {
            //首先打开 TempAssembly.sldasm
            //运行后,程序会把装配体中的Clamp1零件替换成Clamp2

            ISldWorks swApp = Utility.ConnectToSolidWorks();

            ModelDoc2 swModel = swApp.ActiveDoc;

            ModelDocExtension swModelDocExt = (ModelDocExtension)swModel.Extension;

            SelectionMgr selectionMgr = swModel.SelectionManager;

            AssemblyDoc assemblyDoc = (AssemblyDoc)swModel;

            //替换为同目录下的clamp2
            string ReplacePartPath = Path.GetDirectoryName(swModel.GetPathName()) + @"\clamp2.sldprt";

            bool boolstatus;

            //选择当前的clamp1
            boolstatus = swModelDocExt.SelectByID2("clamp1-1@TempAssembly", "COMPONENT", 0, 0, 0, false, 0, null, 0);

            boolstatus = assemblyDoc.ReplaceComponents2(ReplacePartPath, "", false, 0, true);

            if (boolstatus == true)
            {
                MessageBox.Show("替换完成!");
            }
        }
