Problème d'échelle

[vsjdb]

Bonsoir à tous !

J'ai un petit souçi avec autoCAD (je débute),
J'ouvre autocad pour commencer un nouveau plan, l'échelle est réglé sur 1:1, je tape la commande UNIT et je règle sur mètre.

J'ai ensuite tracé ma trame de plan et vérifié que les mesures étaient correctes, chaque verticale est censée faire 10m : 

Jusqu'ici tout va bien, même le dessin à quand même l'air a une échelle très très petite.
Et quand je vais dans l'onglet présentation, normalement mon plan rentre sur un A4, on constate bien que il y a un gros problème d'échelle, mon plan étant le tout petit point sur l'image suivante, entre X et Y...

Voilà... 

Merci de votre aide !

Adjust the viewport scale where indicated on the reference image below.

the right scale here is 1:100.
sorry i forgot to mention it.

my plan is suppose to be ok (sorry for the english) in a A4 at the scale 1:100...

that's the problem !

I understand your problem now (sorry, I don't speak French).  What scale does the viewport report when you ZOOM > Extents from within the viewport?  That might give you a clue as to what's going on.  Is your A4 viewport drawn at 0.21m x 0.297m and not 210m x 297m?

and about my A4 viewport : 

everything seems fine to me...

Maybe you understand something that i don't with the scale 4:1....

Thank you ! 

(ps : autoCAD is complicated, but talking about autoCAD in english is even more ahah)

Nothing is immediately occurring to me, but perhaps others here who use metric units will see something obvious.

In the meantime, you may have more success in the Français forum:

yep i first wrote here and then i 've realized it was the english forum, so i post in the french one. I couldn't delete my post here !

anyway, thank you for your help !

I still can't figure out why you're getting a 4:1 ratio, but one thing I noticed is that I think your paper space units should be set to 1000 (mm) since that is the conversion that will equal your drawing units setting of 1 meter.

this is it !!
thank you very much 😉

Great!  Glad it is working for you now.
