MapControl加載CAD數據的示例代碼
cadFile代表AutoCad文件的路徑
private void btnLoadCAD_Click(object sender, EventArgs e)
{
string cadFile = @"F:AEStudyzxgTest.dwg"; string workspacePath = System.IO.Path.GetDirectoryName(cadFile); string fileName = System.IO.Path.GetFileName(cadFile); //Add passed file to MapControl ICadDrawingDataset cadDrawingDataset = GetCadDataset(workspacePath, fileName); if (cadDrawingDataset == null) return; ICadLayer cadLayer = new#p#分頁標題#e# CadLayerClass(); cadLayer.CadDrawingDataset = cadDrawingDataset; cadLayer.Name = fileName; mapMain.AddLayer(cadLayer, 0);
} private ICadDrawingDataset GetCadDataset(string cadWorkspacePath, string cadFileName) { //Create a WorkspaceName object IWorkspaceName workspaceName = new WorkspaceNameClass(); workspaceName.WorkspaceFactoryProgID = "esriDataSourcesFile.CadWorkspaceFactory"; workspaceName.PathName = cadWorkspacePath; //Create a CadDrawingName object IDatasetName cadDatasetName #p#分頁標題#e#= new CadDrawingNameClass(); cadDatasetName.Name = cadFileName; cadDatasetName.WorkspaceName = workspaceName; //Open the CAD drawing IName name = (IName)cadDatasetName; return (ICadDrawingDataset)name.Open(); }
比較困惑的是AutoCAD和地圖文件的坐標怎么匹配。
