Scaling lisp in one direction

Please guys, I need AutCAD Lips or Macro or any method to scale a 3D object in one direction only without converting it to block. please I need it urgent. Thanks

For sure it depends of the geometry of the said solid, but for some cases the PRESSPULL command or SOLIDEDIT (move/extrude faces) may help you.

If the '3D Object' is a 3DSolid (and it sounds like it is) then there may not be a viable option.

How complex is this object? can you post the geometry?

Edit:

Yeah, what MSasu said.

When you say you don't want it converted to a block, may it be converted temporarily, scaled and then exploded?

Thank you for your response, and it's a complicated shape it's a Clamp and it consists from more than 6 parts and it's a union of all these parts.

really I can't convert it ti a block and explode it againg I'm using xdata in this object it will be makes a many problems for me. thank you

Maybe I miss something, but a block containg a solid once scalled with different factors on axis cannot be exploded.

sure u r right so I need another method to perform this scaling in one direction on 3D solid

As I mentioned previously, I don't think you will find a viable automated, AutoCAD only process. Post an example of the geometry. Perhaps we can offer other options.
