Mesh looks edgy in object mode and smooth in sculpt mode I encounter a weird problem working with a mesh.While in object mode, the mesh looks edgy but when in sculpt mode the mesh looks smooth.The mesh has 2804 polygons.
I also tried to apply a multi resolution modifier but not even a single change took place.

What is the cause of this problem and how can i solve it ?Thanks.
I solved the problem by exporting the mesh in a Wavefront format (obj).When I exported it I checked Selection only and unchecked everything else.Then in a new project I imported the obj file and it seems to behave normal now.
