I'm trying to cut the mesh in grey with the plane in yellow to get a rounded face. I tried with the Bolean Modifier but no way it doesn't work. I'm using the version 2.7. enter image description hereThanks for your help.

    $\begingroup$ Cutting that shape with Boolean will work after you extrude the plane thus making it manifold. Other than that to cut with this plane use Knife Project. Related - blender.stackexchange.com/questions/7928/… $\endgroup$ – Mr Zak Sep 16 '16 at 16:43
  • $\begingroup$ Thanks Mr Zak. I tried it, extruding the vertical plane but nothing happens as I use Bolean Modifier. Maybe thsi si because the grey mesh has both opposite faces open? $\endgroup$ – Grobby Sep 16 '16 at 16:48

  • $\begingroup$ Yes, the object to be cut shouldn't have any holes too (although it can work depending on the case), so both objects should be manifold. $\endgroup$ – Mr Zak Sep 16 '16 at 16:51
