在过去的两天里,我一直在寻找示例代码,其中包含可以帮助我理解 Autocad API 的步骤。所以我可以使用 C# 中的代码。
[CommandMethod("LISTGEn")]
public static void ListEntities()
{
Document acDoc = Autodesk.AutoCAD.ApplicationServices.Core.Application.DocumentManager.MdiActiveDocument;
Database acCurDb = acDoc.Database;
using (Transaction acTrans = acCurDb.TransactionManager.StartTransaction())
{
// Open the Block table record for read
BlockTable acBlkTbl;
acBlkTbl = acTrans.GetObject(acCurDb.BlockTableId,OpenMode.ForRead) as BlockTable;
// Open the Block table record Model space for read
BlockTableRecord acBlkTblRec;
acBlkTblRec = acTrans.GetObject(acBlkTbl[BlockTableRecord.ModelSpace],OpenMode.ForRead) as BlockTableRecord;
int nCnt = 0;
acDoc.Editor.WriteMessage("\nModel space objects: ");
// Step through each object in Model space and
// display the type of object found
foreach (ObjectId acObjId in acBlkTblRec)
{
acDoc.Editor.WriteMessage("\n" + acObjId.ObjectClass.DxfName);
nCnt = nCnt + 1;
}
acDoc.Editor.WriteMessage(nCnt.ToString());
// If no objects are found then display a message
if (nCnt == 0)
{
acDoc.Editor.WriteMessage("\n No objects found");
}
// Dispose of the transaction
}
}
我可以运行上面的代码,但它不能正常运行。我很难理解如何让它与 Autocad 一起工作。我引用了 OjectARX SDK,我正在使用 VS2010 和 Autocad 2012。感谢您的帮助。
