Group objects via lisp

I have two entities stored in variables 'g1' and 'g2'.

What is the best way to create an un-named group with these objects?

so far:

(command "-group" "create" "*" "" g1 g2 "")

Is there a better way?

Thanks,

Casey

 

Unfortunately, I am definately a rookie when it comes to VBA. I have some
knowledge of lisp so "Use thier handles." just isn't quite enough for me to
go on.

Any further direction would be greatly appreciated.

Thanks,

Creating a selection set from the entities you
want to group would be a "better" method, IMO.

Not sure I see what handles have to do with this.

 

Currently g1 is an entity name of an object selected by the user.
g2 is an entity name of an object created using entmake.

What benefit would creating a single selection set with two objects have
instead of simply passing the two objects on to the 'group' command. Seems
like one extra step to me.

Is there a better way that perhaps doesn use the (command "-group"....
method?

Thanks,

Casey,

Here's one way.

;; argument: a list of vla-objects
(defun MakeUnnamedGroup ( lst / groups newgrp )
(setq groups (vla-get-groups
(vla-get-activedocument
(vlax-get-acad-object))))
(setq newgrp (vlax-invoke groups 'Add "*"))
(vlax-invoke newgrp 'AppendItems lst)
)

I wasn't sure how the objects where being
assigned to g1 and g2. Now that I know,
I don't see any advantage in creating a
selection set.

 

Okay,

Thanks for all your input..
