  1. Autosmooth off with smooth shaded

enter image description here

  1. Autosmooth on with Mark Sharp

I come from a 3dsMax background so the usual process is to create a mesh, some of the elements are bevelled all around while some have no bevelling. I would set the smoothing of the entire object to 1 smoothing groups making all the bevelled elements perfect while the unbevelled ones will look bad. Then manual set smoothing groups for those elements. All this is done on a single merged mesh.

I'm replicating this process of modeling in blender but i have issues. The mark sharp on the autosmoothed off version does not seam to harden the edges. Trying to clear sharp on the autosmoothed version does not work as well.

Is there anyway to do this other than edge split? I believe edge split literally splits the edges which is not what I want.

Right, I added the blend file. Using blender 2.90

    $\begingroup$ Hello, not really sure if it's what you are looking for, but have you tried lowering or increasing the angle value next to the "autosmooth" tickbox ? (=Auto Smooth Angle) $\endgroup$ – Gorgious Sep 28 '20 at 13:57

    $\begingroup$ Hello :). Works just fine for me, consider sharing the file so others can take a closer look. $\endgroup$ – Jachym Michal Sep 28 '20 at 16:25

    $\begingroup$ Coming from 3DS to Blender, you're changing the definition of smoothing groups from smoothed regions to their boundaries. The (misnamed?) Autosmooth must be switched on to introduce a layer of per-face-corner normals, as opposed to simple vertex normals. Given Autosmooth, 'Mark Sharp' prevents interpolations of face-normals over the marked edge, whether or not the Edge Split modifier is used to physically separate the faces.. see blender.stackexchange.com/a/156718/35559 $\endgroup$ – Robin Betts Sep 29 '20 at 10:08

Considering you are talking about the Look of the Normal, here's what you can do -

Select the Edges you want to make them Sharper, now press Ctrl + E or go to Edge menu, Select Mark Sharp.

Now You will get the Marked edges sharp with the smoothing you applied.
