Vertices , rings or segments

Support Modeling

Hello

how can i add : vertices , rings or segments to a solid primitive after creating it ?

I’d like to smooth them out, with the same creation features, long after I’ve created them.

Maybe just recreate it with more vertices? To make it rounder first subdivide (not rounder yet) and then select each cap in edit mode an use the loop tools to make it rounder. for sundividing the edges just use edge ring select and sund…

I think the exact thing you want, to smooth them out with the same creation features, isn’t possible because once the object is created and you do another action (i.e. you can’t use F9 to get the menu back), Blender doesn’t “know” what the object is, despite the default names. Blender just sees it as a collection of vertices, faces, normals.

To smooth out objects in general, you can add a Catmull-Clark subdivision surface modifier wit CTRL-1 in object mode (higher number for smoother)… but this smooths out every edge in the object. For the cylinder in your picture, to keep the end cap edges crisp, there are several options.

  1. edit mode → select the end cap loops and Shift-E to “crease” them so that the subdivision won’t affect those edges
  2. use more edge loops around the ends to define the bevel or softness of the edge
  3. use the “auto smooth” setting Properties → Object Data Properties → Normals → Auto Smooth

I think there are other ways using other modifiers but those are the basic ones

Is it possible to use :crease for bevel of any size ?

and then, is it possible to simplify the subdivided mesh for more edits in edit mode without losing the smoothness? or apply boolean for example?

  1. I think crease can only make the appearance of really small bevels. What you probably want is the bevel modifier, because it’s non-destructive. Hard surface stuff isn’t my specialty though, I’m sorry.

  2. If you’ve used a modifier you can always turn it off and on until you “apply” it, I don’t know how to explain this well. There are many good tutorials on Hard Surface Modelling on YouTube and other places.

With booleans it can be complicated depending on how the vertices line up on various faces. Once again, though, you can use a boolean modifier so that you can always reverse it, and play around with settings, until you get it right. Unfortunately a lot if this depends on exactly what you’re trying to do.

modifier remesh efficiently simplifies subdivided mesh while preserving smoothness ?

are there other ways to do this? modifier ? addon ?

And you don’t just wanna make them look smooth ? … then Shaded Smooth for the side faces would be an option (maybe have to make extra edges).

For something like a cylinder, it’s pretty straight forward. Select the two end caps, go into edge mode so only the edges of them are selected. RMB and subdivide, then RMB Looptools->circle, that will double the number. Now this only works for circular items, NOT semi-circular.
