Im trying to render this lid but i cant seem to get the texture to shade smooth. The models has been imported from solidworks. ive tried everything from edgesplit and subdivsion to UV mapping reduce the 'lines' when i render but im still new to blender and dont know what else to do. How do i get the main face (the cylindrical face) of the lid to render properly? enter image description here

    $\begingroup$ Hello, it would be faster to re-do it from scratch, just create a cylinder, scale in down on Z in Edit mode, and bevel the top face $\endgroup$

  • $\begingroup$ @moonboots I don't know if this is sufficient, there seems to be a notch or something in the top face. $\endgroup$ Jul 11, 2022 at 12:01
  • $\begingroup$ was considering doing it from scratch but was wondering if there was anything i could do to keep the part as part of the assembly it was imported with as opposed to adding a new model first. but ill have to try re-doing it from scratch $\endgroup$ Jul 11, 2022 at 12:19

  • $\begingroup$ @Raeshaan Goh maybe share your file to see if we can shade smooth $\endgroup$

I also suggest remodelling. Find the dimensions of the object in Item Tab on the right 3D Viewport Menu enter image description here

and manually set the dimensions on the new cylinder. Then just select the outer edge rim and Ctrl+B create the Bevel, or add Bevel modifier.

This area is causing the problem, since it is not a completely flat surface.

  • $\begingroup$ This solution is more or less what @moonboots wrote in his comment, but still one questions persists: this is an imported object which seems to be designed with a notch on top. Of course that's what's making problems, but if it is intentionally there, simply creating a cylinder with a bevel will not create the same object. But since the OP doesn't seem to mind, it may be some mistake in the model... so, nevermind. $\endgroup$ Jul 11, 2022 at 15:15
