Dynamic Block, need to keep a profile centered...

[Marlec]

Hello Group!

In the attached block, the "Cloison intérieur - Double-E" visibility state, I need to keep the "Distance2" centered in "Distance1"...

Because of my recent years on Revit, I keep trying constraints that are in Revit but not Cad, been a while since I created blocks in cad...

Thanks in advance for the time you'll allow to me!

Sincere regards

Assuming I understand what you want, that's easy enough.  See screencast.

dam...

I keep rewatching  your screencast and I keep missing the moment where you add a "control" that keeps the 2nd stretch centered...

I've done the same has the screen (at least from what I can figure) and the profile follows the stretch but doesnt keep centered...

1- you've 1st checked how I did me block

2- drawn a total of 4x "XL_H" to check if the profile is centered?

3- erased all 4 "XL_H"

4- add a Stretch action on Distance1... 

I think there is the part I keep missing the link between the 2 stretches...

You need to select the new stretch action, go to properties, and change the distance modifier to 0.5.  That chance to the distance modifier means that for every unit the linear parameter is changed, the stretch action will stretch 0.5 units.  It can also be easier to see the steps in the screencast if you make it fullscreen, set the playback speed to 0.5, and pause often.
