Looking for a LISP routine similar to Image command, and another similar to XClip

[BCrouse]

I am looking for 2 lisp routines. The lisp routine would need to work with blocks. .

The 1st lisp routine would work similar to an image. I should allow the user to choose which block is front or behind.

The 2nd lisp routine show work like xclip. The block would have to xclip the block that it is in front of. Basically a Auto Xclip.

If you want a dwg file that shows what I am asking. I will load it upon request.

Thank you,

Brad
