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#)

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

            }

            //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);
