how to parameterize a component by maintaining unaltered thickness

[Bonfi]

good evening to all, as already indicated by the title, I would have the need to parameterize a sheet component, increasing its size of 0.5 mm per side rails, only that with the "direct" command I do not get the desired effect, but I get only an increase in thickness, so, I would like to know if there is a command that allows me to parameterize the piece while keeping the thickness unchanged.
below I leave a ".rar" file containing the above component.
Thank you so much in advance to all, good evening.

I realized this, in the hope of having interpreted your problem
Let me know.

Hi! I'm sorry, but that's not what I meant, maybe I was wrong in the question, because it was my intention to avoid having to redesign the part, I hoped there would be a method to change the original directly.
said that, I thank you infinitely for trying to help me solve the problem!

If you better explain, maybe someone can help you.
from what little I understand I can suggest you make a copy of the file with pack and go, vault or design assistant depending on what you use and then edit it where you need it.

Okay now I think I understand
you have to use the "direct" command that will allow you to "stiar" each side similarly to autocad (crossing window to select)
if the value of "stira" parameterization by renameing the variable (e.g. delta_x, delta_y etc....) then by fx parameters, you can resize it to pleasure

Thank you very much; at the end of the accounts I thought you had to use a more specific command, in fact I was wrong to use the "direct" command.
I'm sorry I complicated your life because of my question mail bad ahahaha thank you so much again!!!
