C# SolidWorks二次开发 API-尺寸链标注

今天天气好，适合放大招。
快过年了，提前祝大家

先上结果吧，尺寸链标注:

主要功能就是针对视图上的一些孔，进行尺寸链标注。
主要代码如下:

        private void btnOrdinateDimension_Click(object sender, EventArgs e)
        {

            //请先打开HolePlate-2.slddrw文件

            var swApp = PStandAlone.GetSolidWorks();

            var swModel = (ModelDoc2)swApp.ActiveDoc;

            var swDrawing = (DrawingDoc)swModel;

            //这里改成工程图中的视图名称

            swDrawing.ActivateView("Drawing View1");


            #region 遍历并删除
            //得到视图对象
            var swView = (View)swDrawing.ActiveDrawingView;


            //找最小点
            var baseOrigin = FindOriginVertex(swApp, swView);

            var circleEdges = AddCenterPointForCircle(swApp, swView);

            //视图的外围位置 

            var viewLoc = (double[])swView.GetOutline();


            (baseOrigin as Entity).Select(false);

            // 这里还有个坐标相同的处理可以优化。

            foreach (var item in circleEdges)
            {
                (item as Entity).Select(true);

            }


            swDrawing.AddOrdinateDimension2((int)swAddOrdinateDims_e.swHorizontalOrdinate, 0, viewLoc[1] - 0.01, 0);


            (baseOrigin as Entity).Select(false);

            foreach (var item in circleEdges)
            {
                (item as Entity).Select(true);

            }

            swDrawing.AddOrdinateDimension2((int)swAddOrdinateDims_e.swVerticalOrdinate, viewLoc[0] - 0.01, 0, 0);

            #endregion




            MessageBox.Show("操作完成");



        }

        public Vertex FindOriginVertex(SldWorks swApp, View view)
        {
            Vertex resVertex = null;

            var vComps = (object[])view.GetVisibleComponents();

            foreach (var Comp in vComps)
            {
                var swComp = (Component2)Comp;
                //所以可见点
                var visbaleEnts = (object[])view.GetVisibleEntities2(swComp, (int)swViewEntityType_e.swViewEntityType_Vertex);

                for (int i = 0; i < visbaleEnts.Count(); i++)
                {
                    var swVertex = (Vertex)visbaleEnts[i];
                    (swVertex as Entity).Select(false);
                    if (resVertex == null)
                    {
                        resVertex = swVertex;

                    }
                    else
                    {
                        var vCurOrigCoord = GetVertexCoordinate(swApp, resVertex, view.ModelToViewTransform);
                        var vCoord = GetVertexCoordinate(swApp, swVertex, view.ModelToViewTransform);

                        if (vCoord[0] < vCurOrigCoord[0] && vCoord[1] < vCurOrigCoord[1])
                        {

                            resVertex = swVertex;
                        }



                    }


                }



            }

            return resVertex;

        }

        public List<Edge> AddCenterPointForCircle(SldWorks swApp, View view)
        {
            List<Edge> res = new List<Edge>();



            var vComps = (object[])view.GetVisibleComponents();

            foreach (var Comp in vComps)
            {
                var swComp = (Component2)Comp;
                //所有可见面
                var visbaleEnts = (object[])view.GetVisibleEntities2(swComp, (int)swViewEntityType_e.swViewEntityType_Face);

                for (int i = 0; i < visbaleEnts.Count(); i++)
                {
                    var swFace = (Face2)visbaleEnts[i];

                    var swThisLoop = (Loop2)swFace.GetFirstLoop();
                    while ((swThisLoop != null))
                    {
                        // Hole is inner loop
                        // Circular or elliptical hole has only one edge
                        bool bCount;
                        var bRet = swThisLoop.IsOuter();  //外环
                        var count = swThisLoop.GetEdgeCount(); //边数
                        if (count != 1 && count != 4)
                        {
                            bCount = false;
                        }
                        else
                        {
                            var edges = (object[])swThisLoop.GetEdges();

                            foreach (var e in edges)
                            {
                                var tempEdge = e as Edge;

                                if (tempEdge.IGetCurve().IsCircle())
                                {
                                    res.Add(tempEdge);
                                }
                            }

                            bCount = true;
                        }


                        // Move on to the next
                        swThisLoop = (Loop2)swThisLoop.GetNext();
                    }




                }



            }


            return res;

        }



        private double[] GetVertexCoordinate(SldWorks swApp, Vertex resVertex, MathTransform swViewTransform)
        {
            var vCoorPt = resVertex.GetPoint();
            var swMathPt = (MathPoint)swApp.IGetMathUtility().CreatePoint(vCoorPt);
            swMathPt = (MathPoint)swMathPt.MultiplyTransform(swViewTransform);
            return (double[])swMathPt.ArrayData;
        }

顺带讲一讲思路，通过Solidworks提供的一些API去找到工程图上视图的一些点 边 过滤后进行相应的标注动作。
源码还是在gitee上，国内下载比较快。github有些人还上不去。
需要的自取哈
