Hi i am trying to model mobile phone and everything is going just fine until i try to cut holes for the buttons, then all geometry is messed up.
I tried with boolean and shapemerge commands and the result is the same. Iif anyone can tell me which is the best way to cut holes and not to mess up the geometry please help.
And by the way i made the main body of the model from simple plane,then with splines and the result is the same.

Start with the holes. That may sound silly, but trying to cut holes in a mesh is always tricky, so make them first, extrude the edges for the main body. Presumably you will be smoothing it, so make certain that you don’t have triangles on any curved edges - they do not smooth well.

Also http://area.autodesk.com/for...-with-mesh-after-boolean/ - not phone related, and quite long, but relevent to the general principles.

It helps us if you put your Max version, and brief system specs, in your sig - saves us havig to ask ;-)

Max 4.2 through 2013.
XP-64 (SP2)
NVidia 9800GTX-512 (Driver 266.58).
Core 2 Quad Q6600 2.4GHz, 8Gb Ram, DX9.0c.

i am not sure if i should be giving any advices since i am a beginner myself but i noticed that it helps if you have an edge on the geometry that you are cutting the hole from. So before i cut holes in to anything i make sure that i add an edge close to the middle of the place where the hole will be. That helps sometimes. And if you are smoothing it do it before you cut the holes.

Ok sorry for my late response, finally i managed to solve my problem it is a bit weird here i have attached sample render from the mask of the phone. The one on the left side i made with proboolean command and the right one with messed geometry is with boolean command .
So for this kind of shapes it seems that proboolean command works better.
Thanks for your help.
