it seems to do it when i extrude, but if i delete the gear hole i t goes back to normal?A little tip for better results for smoothing groups later. Make sure that each visible poly is made up of no more than 4 edges or 4 verts. I've attached an example of where to connect verts using your above pic. Pols made of more than 4 edges or verts is known as an ngon. FYI
fixed it by deleting the inside faces, as said before the real model so doesn't have wheel wells so its no big deal for now but thank you for the advice i'll be sure to use it the next time i run into that problem!it seems to do it when i extrude, but if i delete the gear hole i t goes back to normal?
I knew something was off. By looking, you hit a on the tube. What about the turbine? Just delete the time and try again.7,470 without the turbine and tumble tube ?
