Subdivide and smooth

Blah11 · 6 Mar 2009, 06:00

I hear so many people talking about it and I really want to get into designing cars in sketchup I love what people have done already. ALSO my gundam work doesn't feel like it as smooth as it could be or should be.

Subdivide and smooth is not really for smoothing its more for modeling smooth (organic) things. depends what your trying to do i guess.
Actually, smoothing existing models is one of the primary functions of the plugin. For example, you can create a faceted tube and then smooth it with the plugin. Don't confuse the plugin with 'edge softening' or 'normal smoothing' which can already be done inside SketchUp.

xrok1 is right that the plugin is great for modelling organic things.

so if I were to use this plugin my models would seem "rounder" around the edges. Say I make a blocky sphere and I use this plugin would it make it seem more natural instead of blocky? If it does then I'm sold.

Yup.

all rite seems fair enough I can safely say I need this program so I guess I can part with $22 but it seems quite allot for a plugin anyhow I guess I'm not THAT cheap LOL. Does this work in sketchup 7?

solo · 6 Mar 2009, 22:39

$22 for a plugin that will change your SU experiance and with a little practice will open up the world of organic modeling, me thinks that's a steal.

Yes it does work with SU7

OK I found a sub division demo but I have problems now Heres the link to the demo http://www.smustard.com/script/Subdivide

Now heres my problems and I want to know if this is like this in the final version.

heres the original

heres when I subdivide

heres a closeup to the problem

This wont do this in the final version will it? I do want subdivisions in my model though I at least want to keep the basic shape.

You have the wrong subdivide ruby there, the one you want is Whaat's 'Subdivide and SMOOTH'

yes I know though I thought that the subdivide would be the same thing in subdivide and smooth unless its not. I just wanna make sure I'm not wasting money =]
I'm afraid that the subdivide will end up moving the corners on the model and if it messes with the corners that would mess up the whole shape.

Although similar, that script is a lot less polished than whaats version.

With whaats version, when you select a face to subdivide it subdivides all the connected geometry. And to answer your question, no you shouldnt get geometry like that.

beat me to it solo.

and blah...

remus · 6 Mar 2009, 23:12

With whaats version you can 'crease' edges and vertices, this essentially locks them in place and subdivides geometry around them, so you can make sure bits of your model stay put when you need them to.

OMG I want this plugin so bad now gotta wait until paycheck =[ Imma update all my models with this.

david_h · 11 Mar 2009, 23:23

I am working in Sub Smoove and One thing I have always wondered is . . .is it possible to select multiple edges of the proxy for creasing or is it always necessary to do it one at a time?

remus · 11 Mar 2009, 23:45

David, theres a 'crease selection' option in the SDS tool menu, i think it gives you the option to do edges, vertices or both.

This script does a Catmull-Clark subdivision. Does anyone know if there is one which uses doo sabin technique ?

remus · 11 Mar 2009, 23:48

I dont know of a script that uses the doo-sabin algorithm, although if any budding ruby scripters fancy a challenge theres a good explanation here: http://graphics.cs.ucdavis.edu/education/CAGDNotes/Doo-Sabin/Doo-Sabin.html

Does it allow for Multiple Selection? that was the gyst of the question.

Thx,
