urbanista, i've taken a peak at your block which has a lot of issues...

first there are too many distance parameters when only four would be required...fist one is for the overall width (your "width"), the second one for the left bay ("distance 3"), the third is for the right bay ("distance 5") --no need for one in the middle bay as the other two would take care of it, and the fourth for the frame depth ("frame width" --depth?)...

now regaridng you actions...you can apply more then one action per parameter so there was no need to create a second linear parameter (called "distance") to create a move parameter for the glass...you could have create a "move" action and associated it to the "frame width"...

now this can become a lengthly tutorial trying to explain how to improve your block...however, even at the risk of doing the work for you, i've decided to modify your block with the below explanations...hopefully you can study and understand what i've done for future reference....so here we go...

-------
"width"...

i've edited the stretch action to include the complete end of you window...all that was missing there was to include the glass with the stretch and "distance 5" (see below)..."distance 5" needs to be included so that the endpoint/grip will follow the "width"/"stretch 1"...
----------

"distance 3"...

the "stretch 2" action had no objects associate to it...i redefine the stretch frame to only include the glass and the mullion...do not add the int/ext magenta frame lines as the "stretch" will move them and add to the "stretch 1" causing the line to extend past the end (which is similar to your original problem w/ your block--right?)...

now, i also turned on 1 grip for "distance 3" so a grip will be available to stretch the mullion...

-------

"distance 5"

i had to recreate the linear parameter by drawing it from right to left so that the "1 grip" would appear on the left side for stretching...once that was done i needed to include this paraneter as part of the stretch action for the overall width so when you alter the width "distance 5" will alter with it...

to associate it with "stretch 1" double click on it to get

Specify first corner of stretch frame or [CPolygon]: and hit the escape key because we do not need to change the CP..so the next line is
select object to add to action set or [Remove]:...i typee add (just to make sure) and select "distance 5" and hit enter...

next is to alter "stretch 4" CP area and the objects it needs to include--much like for "stretch 2"...you need to only add the glass, the vertical frame elements and "stretch 5" parameter...

-----------------

"frame width"

i deleted the original "distance/move" because you can assign another action to the "frame width" parameter...so i create a new move action, selected "frame width" and picked the glass objects...and as you have correctly done so previously, the distance multiplier was set to 0.5...

to the "frame width" i changed the number of grips to 1 so we can change the frame depth on screen...

-----

i closed the block editor and tested the block...all seems fine!..

i hope this response can help you/others out...if you have any difficulties or further question by all mean keep posting here...

hey there hazardman,

thankyou sincerely for your reply and mods. rather unexpected to say the least.

i have travelled to the east of your fair country. loved it.
i am quite keen to move there someday.

to the business.....

i have inserted the mod block into a new dwg. i loathe to say that the mullions dont move for me. the stretch for the last pane works brilliantly. i understand the logic now after spending some time in bedit looking at it.

i will tinker over the weekend and will post up again early next week.
i need to get it wired - i am 100 percent i can get it.......

again, thanks for the help man. great stuff.

trust this finds you enjoying the mind bend that acad can be.

regards

i just spent the last week and a half creating a library of dynamic blocks and know how frustrasting it can be...just thought to spread some joy......

your appreciation is, well, appreciated...
