I want to stretch multiple dynamic blocks at once

[cadcoke5]

I want to be able to stretch multiple dynamic blocks at once.  In this case, I am creating a guardrail with 1 1/2" Square Tubing. I am on AutoCAD LT, and realize I might create the handrails using just constraints. But, I also like the way dynamic blocks have attributes that I can extract and use to create a cut-list.

I can't seem to find a way to stretch multiple dynamic blocks at the same time.  I had hoped that I could select multiple dynamic blocks, so that their handles are all visible. Then, use the standard STRETCH command to change their lengths. But it seems like that is not possible.  Is there perhaps another approach you would recommend?

Attached are some images showing my goal.  One shows a completed guardrail without the dimensions. The other shows multiple dynamic blocks, with two of them selected so that their handles show.

You cannot use constraints in LT.

If you give your parameters the same name in each block you can stretch them both using the properties (Ctrl+1).

Thank you for the reply, and idea.  I may use that.  Though, I suspect it requires that each of the Sq Tubes in my example would have to be contained within the same block, or the same drawing, without any other objects using the same parameter name.  So, the idea might as well be handled by a stretch feature of a dynamic block using normal Acad lines.  That is available in AutoCAD LT.

And while I have never seen a phrase like "you can't stretch multiple dynamic blocks", I am guessing that it is not possible.  Though, I theorize it may be possible with a 3rd party program, that would recognize the dblock grips associated with move and stretch functions when they were within a crossing selection window.

I did just find an app that can do what I am seeking.  But, it requires the full version of Acad.
