dynamic block with corner

[Sblindo]

Good morning.
I created a dynamic block for a flat screen.
I have two parameters, length and width.
Unfortunately, to vary these parameters, the dishes in question are deformed.
What do I need to set (if possible) further?
Thank you.

I didn't understand what you mean, but if you want me to change a size, everything is proportionally applied then you have to take off the stocks and replace them with two scale actions.

According to me in this dynamic block it is necessary to use the parameterization of the geometries. I enjoy myself a bit and then I load my version

Try to see if you like it...
I had to create an additional layer for objects needed to maintain constraints

Perfect!
Thank you very much.
