how to keep sharp turns on model while sub surf modifier is active? (image inside) [duplicate]

I would like a sharp turn, not the smoothed round turn that the sub surf modifier causes. Is this possible? Notice the purple line for the mean crease, I would like it to look like that

• Use Shift+E while in edit mode while you have the two adjacent edges selected, adding answer (only works on a 3D object) Use loopcuts for 2D ones. – VRM Apr 6 '15 at 0:33
• if it helps, I had solidify modifier on but not applied. I increased the original edge crease weight to 1. Maybe if I applied solidify and then increase the crease weight to 1 on the whole face it would fix it? – luigi Apr 6 '15 at 0:36
• Read my answer. \The solidify modifier is based off of a 2D mesh, so creases do not work. You need to crease the seam. If you apply the solidify modifier it should work though. – VRM Apr 6 '15 at 0:48
