composant dynamique: comment modifier sans déformer ?

JNL

Bonjour à tous,

ça faisait un moment que je n'étais pas passé vous voir et j'ai, d'abord, cru que je m'étais trompé de site
et découvert que Maître Pilou avait failli lâcher la souris...
face à cette nouvelle interface, je ne retrouve plus rien; c'est pourquoi cette question qui a certainement été déjà traitée (et je vous prie de bien vouloir m'en excuser):
comment empêcher la déformation d'un composant dynamique quand on en modifie une des dimensions ,
j'ai une cornière dont j'aimerais faire varier la dimension d'une des ailes sans en modifier l'épaisseur

merci de vos conseils, toujours avisés...

divide into 3 solid groups, groups are good as subs as will not show on OCL, and if required can union or outer shell with no residue

hide the adjoining planes

fix the thickness and formula for base and leg

amended to include position so can change base width

@pcmoor Great. A thousand thanks ! it works nickel.
btw, I totally didn't know that dynamic components could have groups and, above all, control them.

Is it possible to drive a group, i.e. part of a child component (as you suggest) from an option of the parent component?
When I try, I always get an error message written in red...

@JNL
Subgroups work on the lowest level, they are convenient as stated. But should not be used in intermediate levels, unless used in conjunction with "deep make unique" or similar extensions.

Can drive from parent, the red may show a non-initiated attribute. Though shows "0" in grey, the value in parent is null. So, enter a value.
Otherwise, the formula is incorrect or sometimes disconnected.
Please upload any problem DCs

I'm afraid I don't understand what I have to do
I'm attaching to you the file that's the problem with me :
tiroir_EMUCA.skp
I split the component into 3 subgroups, as you suggested.

I would like to change the length and height of "côté_métallique_EMUCA" by modifying only "partie_haute" which is one of the subgroups.

Is that possible, do you think?

Thank you in advance for spending time on my little problem

I understand now, you cannot reference the top level, only the level above or below and any within the same level.
So, need to pass the data through

You can use parent! as a generic reference which is handy for reusing a DC (note make unique if reusing)
