Problem with extuding I used to be get face from each side now when i extrude any object even a simple box I can only get the front face not the back face. i tried all help suggestions from other posts like vertices on difference planes and starting with a 3d perimitive but still have the same problem.. what am I missing ? please help. thanks in advance.
All faces are actually single-sided however by default 3dsMax displays a false backface.
This trips up a lot of people and probably should be off by default as people like yourself get unexpected results when using the tools.
To turn off these false backfaces you right-click your model and select Object Properties and then check the box 'Backface Cull'.
Once you have done this you can check to see which way your 'real' faces are actually pointing. If they're pointing in the wrong direction you can flip these by selected the affected faces and then selecting 'flip'.
Knowing this and having all your faces pointing in the correct direction the tools should start to function correctly again or maybe you have a completely different problem here?
Hey bro, It was not a the flipped normals issue although I did ran into problems with it a bit before so I thank you for the backface cull tip 🙂
My original problem was fixed on the double post (which was an accident) and i don't know how to deleted posts here lol.
