Ohhhh ok....thank you very much once again...

Btw is that the only way to fix that?

Thank you...that fixed it...i'll keep that in mind next time....

i've added it in the desc

Sure i'll upload it in a second, ummm on the screenshot, im on the modifers tab with my object in edit mode...

I made sure there were no doubles (W key). I tried Limited dissolves as well as Dissolve edges, buit made no changes...i use a mirror mod for this object and also applied it...this shouldnt bother mid but im planning to add a subsurf mod...so eventually i'll have to smooth with Loops and i might get confused...i've triple checked and i didnt find any ngons...its a quad face...

Yep! Thx i fixed it using triangular faces instead...

ty for the answer...it helped
