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
