Convert a Wall (AEC_WALL) to an Solid3D Object

[Michael-Mair]

Hello,

Can someone explain me how I can change an AEC Wall (AEC_WALL) to an Solid3D Object. I found out that I can extract all Bodies from a Wall with "GetComponentBodies" function, but I do not know how to get this to an Solid3D Object.

Dim wall AsWall = TryCast(trans.GetObject(obj, OpenMode.ForRead), Wall)

Dim bodyColl As New BodyCollection

wall.GetComponentBodies(bodyColl,True, False, True, True, True, True, True)

I know that there is an Autodesk Architectur Command "AECCONVERTTO3DSOLIDS" --> dies is the Command what i need --> but i need the command for .NET.

I hope, anyone can Help me.

Hi Mike，

You can write out the body components of AEC wall to *.sat file to the disk. Then read in this file using the Autodesk.AutoCAD.DatabaseServices.Body.AcisIn(fileName). The Body class in AutoCAD .NET is a 3D solid entity.

Here is the full code to convert the wall to 3D solid.

<code>

[Autodesk.AutoCAD.Runtime.CommandMethod("w2b", "w2b", Autodesk.AutoCAD.Runtime.CommandFlags.Modal)]
public void ConvertWallToAcDbBody()
{
Editor editor = Application.DocumentManager.MdiActiveDocument.Editor;
editor.WriteMessage("\n====================================================\n");


PromptEntityOptions opts = new PromptEntityOptions("\nPick a wall: ");
PromptEntityResult results = null;

results = editor.GetEntity(opts);
ObjectId id = results.ObjectId;

Database db = Application.DocumentManager.MdiActiveDocument.Database;

TransactionManager tm = db.TransactionManager;
Transaction trans = tm.StartTransaction();

Wall w = trans.GetObject(id, OpenMode.ForRead) as Wall;
BodyCollection bc = new BodyCollection();
w.GetComponentBodies(out bc, true, true, true, true, true, true, true);

BlockTable bt = (BlockTable)tm.GetObject(db.BlockTableId, OpenMode.ForRead, false);
BlockTableRecord btr = (BlockTableRecord)tm.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite, false);

String fileName = @"c:\test\mysat.sat";
foreach (Autodesk.Aec.Modeler.Body b in bc)
{

b.SaveToSAT(fileName);

DBObjectCollection collection = Autodesk.AutoCAD.DatabaseServices.Body.AcisIn(fileName);

foreach(DBObject obj in collection)
{
btr.AppendEntity((Autodesk.AutoCAD.DatabaseServices.Entity)obj);
trans.AddNewlyCreatedDBObject(obj, true);
}

}
trans.Commit();

editor.WriteMessage("\n====================================================\n");
}

Hope this helps,
