I am a little curious about subdivision modeling, to see if it might be relevant to the product design work I do here. Some examples would be good. I have only seen various monsters and statues as output, but nothing in the way of mainstream injection-molded products. Can anyone post pictures or a link? I mean of real products, not models.
Thanks

What is sub-division modeling?
Well, I am not sure I am using the right language. I thought it was a design interface, like Solidworks Industrial Conceptual, where the designer pulls and pushes at sub-areas of a surface and makes a blobby out-of-control form. That was my impression, at least, when I tried Solidworks ID.
From other responses here, maybe subdivision modeling is a type of surface definition that exists under-the-hood, independent of the user interface. I don't know. Surfing around the net earlier today, I saw a bunch of videos with people making cartoon figures. At the same time, I heard it mentioned in various abstracts for Solidworks World 2019 - for xDesign, nPower software - are there others?

I tend to follow Josh Mings over at https://www.solidsmack.com/ because he sometimes has neat stories about Sub-D and other modeling software tools. It's cool to see but you're right about wanting to see actual parts.

Steve,
I have really enjoyed many of Josh's articles. There was one in particular that I thought was really informative and hilarious too.
I printed out a copy for each of member of my team at the time, the title of the article (I'm paraphrasing) was: "The Disco Queen of Solidworks Features". Everyone looked at me like I was nuts, but proceeded to enjoy and benefit from the article. Humor and technical info often go very well together.

Any particular article? I went there and searched on "subdivision". There's a 2010 article on Creo, other web-based design programs.
Here's some NX action. That's maybe something you can relate to better. The subd/mesh/poly/point cloud process is much different. You use various tools to manipulate a blob. More like digital clay than building sketches, features, parameters, etc.
Look like Sub-division is for rendering and animation.
It allow a low-ploy mesh to look real.

That's what I thought, but it seems to somehow apply to engineering work. Creo has, I think, "SubDiv" capabiltiies, or I've seen it mentioned.
I know a furniture maker that uses subd modeling. They use it to get the fabric and stuffing on the frame. It is so much more efficient than using nurbs software. So much faster. Think about modeling a car in SW. Now think about doing it in 3dsmax. There's a reason why all the really complex shapes are done in non-nurbs based software.

Sounds good, but I don't know enough to really understand. I have not used 3dsmax, so I can't picture what that process is. Is that a place I should start, 3dsmax? Can I make a real car in 3dsmax, or just a cartoon car? Should I immerse myself in Power Surfacing for SOLIDWORKS trials, to get a better idea? I am sorry for my ignorance, here. I think my run-in with Industrial Conceptual has left me confused.
here are a couple image of cars i made in 3ds MAX and Vray as the renderer. In the Cadillac u can see the low poly mesh and the smoothed high poly. The corvette is a final textured render. Both models are full scale dimensionally accurate. For the most part!
Its a very different work flow for sure. starting from a plane or box and manipulating edges polys and verts. Pushing pulling extruding chamfering. Its a lot of fun though!
Here's a link to everything you wanted to know about sub-d modeling and how it works.
You can go to Youtube and search for NX Realize Shape to see this in action in the CAD environment. It's a pretty powerful tool when implemented correctly! No need to import or translate you are creating usable geometry.
Look for the videos by Miror. This is 5 session tutorial which covers the basic all the ways up. NX Realize Shape | 1 - Introduction - YouTube
