How to make walls with the same thickness? I m noob in modeling and I have one problem with thickness walls of my shopping bag.



I wanna make walls the same thickness, actually I can't do this using E (External) or Solidify modifier. It doesn't work. 



Every distance is different size, can you help me fix it ?
You have uneven scales on all axis (yellow marker). this happens when you scale your object in Object mode.



press  Ctrl  +  A  and select Scale in object mode. That should fix your problem.
