Zoom to selected entities

Anonymous — Thu, 10 Sep 2009 15:23:15 GMT

Hi,

I wrote a simple program which selects some entities from a drawing. Is there a way to zoom to the result programmatically?

namespace MyExtensionMethods
{
public static class EditorExtensionMethods
{
static MethodInfo runCommand = typeof( Editor ).GetMethod(
"RunCommand", BindingFlags.NonPublic | BindingFlags.Instance );

public static PromptStatus Command( this Editor editor, params
object[] args )
{
return (PromptStatus) runCommand.Invoke( editor, new object[] {
args } );
}

public static void ZoomObjects( ObjectId[] ids )
{
Editor editor =
Application.DocumentManager.MdiActiveDocument.Editor;
Application.SetSystemVariable( "CMDECHO", 0 );
Command( editor, "._ZOOM", "_O", ids );
}
}
}

{code}

You have to reselect them because any command that's started
clears the current selection.

You can use this API to select them:

Autodesk.AutoCAD.Internal.Utils.SelectObjects();

You have to add the CommandFlags.Redraw flag to your command
method attribute for the selection to remain after the command ends.

I actually had tried it,

Autodesk.AutoCAD.Internal.Utils.SelectObjects(final_entities);
Autodesk.AutoCAD.Internal.Utils.ZoomObjects(false);
System.Windows.Forms.Application.UseWaitCursor = false;

and also added the CommandFlags.Redraw
The problem is that after zooming, it goes back to its original size, the zoom size does not persist. Edited by: apt42 on Sep 11, 2009 10:53 PM

Tony, how do you go about zooming and selecting in 2009 without internal.utils?

edited... I guess i just needed to add the internal dll to my references. Edited by: ViktorCad on Oct 30, 2009 10:26 PM

You can use Internal.Utils in 2009, you just need to add
a reference to AcMgdInternal.dll.
