Get current selection

[fyathyrio8]

This should be pretty simple - but I haven't been able to find the answer anywhere.

How can I get the current selection set? Editor.GetSelection() will prompt for a new selection, but I would like to check if the user has selected objects before running the command.

Thanks,
Mike

First, you have to have the right command flag(s) set. If you only want to consume the PickFirst Set, and want the selection to clear after your command, then you set the UsePickSet Command Flag. If you want to Add to or Modify the Pickset, leaving the grips or selection on after your command then you use the flag Redraw.

If you do not use either of those flags, then the pickfirst set is cleared immediately when you enter your command.

After that, you can do:
Dim psr As PromptSelectionResult = Editor.SelectImplied

which will give you the pickfirst set if there is one and do nothing if there is not.

or you can do:
Dim psr As PromptSelectionResult = Editor.GetSelection

which will give you the pickfirst set if there is one without prompting the user, or it will prompt the user for selection if there is no pickfirst.

Add the CommandFlags.UsePickSet flag to your CommandMethod attribute,
and GetSelection() will return the pickfirst selection or prompt for a selection
if there's no pickfirst selection.

Do NOT use the SelectImplied() method, because Autodesk screwed up
when they revised it in AutoCAD 2009, and as a result, it no longer sets the
returned selection set to the Previous selection set (as the user expects).

[CommandMethod("mycommand", CommandFlags.UsePickSet)] and Editor.GetSelection() worked out perfectly.

Thanks for your help.

I'm trying to check if a Selection Set exist...but I don't want to prompt the user if there isn't...Is there a way to do this?

Thanks for any guidance!

What version?

I know Tony said 2009 had a problem, but I've used the SelectImplied() method in 2010 without any issues that I've seen.
