Editor's Command method

Anonymous — Tue, 07 Apr 2015 16:55:10 GMT

I'm trying to create a button that, when pressed, marks the position of the drawing. Right now the method looks like this.

[CommandMethod("MARKPOS", CommandFlags.Session)]
public void MarkPosition()
{

Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;
ed.Command("UNDO", "M");

}

However, when I try and execute the method I get the error pictured below and cannot determine why.

************** Exception Text **************

Instead of using the editor to send command, try this

Autodesk.AutoCAD.Internal.Utils.SetUndoMark(True)

Alright, is there a similar way to undo back to the mark?

Yes, to undo back use this

Autodesk.AutoCAD.Internal.Utils.SetUndoMark(False)

Are you sure? It doesn't seem like either Mark or Undo are working...

public static void MarkPosition()
{
Utils.SetUndoMark(true);
ed.WriteMessage("Undo Mark Set");
}

/// <summary>
/// Method to step AutoCAD back to undo mark

/// </summary>
public static void BigUndo()
{
Utils.SetUndoMark(false);
ed.WriteMessage("Undo to Previous Mark Complete");
}

works for me.. (the false settings doesn't trigger the undo event, just closes the undo set) You just have to call undo after closing it?
