AcisIn and acisout in .NET

By Virupaksha Aithal

Below code shows the usage of AcisOut & AcisIn API in importing and exporting of Solid3d.

[CommandMethod("acisout_test")]
public void acisout_test() // This method can have any name
{
    Document doc = Application.DocumentManager.MdiActiveDocument;
    Database db = doc.Database;
    Editor ed = doc.Editor;
 
    PromptSelectionResult result = ed.GetSelection();
 
    if (result.Status != PromptStatus.OK)
    {
     return;
    }
 
    using (Transaction tran = 
                    db.TransactionManager.StartTransaction())
    {
         ObjectId[] Idarray = result.Value.GetObjectIds();
         DBObjectCollection objectCollection = 
                                     new DBObjectCollection();
         DBObject dbObject = null;
         foreach (ObjectId Id in Idarray)
         {
             dbObject = tran.GetObject(Id, OpenMode.ForRead);
 
             if (dbObject is Solid3d || dbObject is 
                        Autodesk.AutoCAD.DatabaseServices.Region 
                                             || dbObject is Body)
             {
                 objectCollection.Add(dbObject);
             }
         }
 
         Body.AcisOut("C:\Temp\test.sat", objectCollection);
         tran.Commit();
    }
}
 
[CommandMethod("acisin_test")]
public void acisin_test() // This method can have any name
{
    //get the working database
    Document doc = Application.DocumentManager.MdiActiveDocument;

    using (Transaction tran =

        BlockTableRecord model = tran.GetObject(
                        table[BlockTableRecord.ModelSpace],
                          OpenMode.ForWrite) as BlockTableRecord;
 
        //use static function of body to read a acis file
        DBObjectCollection MyCollection = 
                               Body.AcisIn("c:\temp\test.sat");
 
        foreach (DBObject ACISInObject in MyCollection)
        {
            if (ACISInObject is Entity)
            {
                Entity ACISEntity = (Entity)ACISInObject;

                tran.AddNewlyCreatedDBObject(ACISEntity, true);
            }
