SubD examples and models
-
It's not my topic, it's a great community topic...
-
btw sometimes when I open a skp with a subd-ed mesh in it, the mesh is invisible (but it's definitely there, as you can select a hollow box and it becomes visible if you toggle the subdivision off)...
Is there a fix for this? what causes this?
-
My Sub D experimentation is under way
-
I've notice a few people I have talked to and read in some post that there is a misconception that SubD isn't well suited to accurate or specific dimensions.
I modeled this as an example of an organic shape flowing into a very accurate connector. This would fit onto the other side of the connector I modeled it from. Right down to the 6.2mm holes to take 6mm contersunk engineering bolt.
This is all one piece and is a solid.
-
Cool result!
What is the render engine used ? -
Twilight Hobby.

That´s a good hint and a nice example as well! (I thought of any new B & O speakers
)
Did you use the normal SU move tool for to snap and fix these exact points then? -

It doesn't really matter how you arrive at the shapes, it's just a matter of using the crease tool to lock them in place.
So if you draw a circle with the normal 24 sides and extrude and expand etc etc but crease the original border of the circle, the hole created by that circle even after subding will be the same as when you created it. So you can happily draw accurate sizes and keep them in the same piece as heavily deformed shapes. Which makes it easier for creating 3d printables.
Mind you, there is no reason I couldn't make the fitting and the "mouth" shape separate pieces, and using the same logic mate them together perfectly via creasing. -

Do you have such a model you can share?
And the mesh isn't missing when you save? It could either be some extension that do something to the model when it saves. Or could it be a graphic card issue?
Do you ever get a SUbD error dialog? -

... again a ... question:
to get these topologies (Cut Face A and B), is there a specific tool or can I draw them the usual way with QFT line tool?... that´s a good question and thanks for your useful picture - in 2D, these "curved direction changes" can be drawn with basic SU tools.
As they are so useful, I´ll add them here if someone wants to use them as "instant groups"
-
thats good! thanks for this workflowjust right click on the gif within your web page and copy the gif´s URL and paste it her - like you would post any other internet linked picture
-
Here's my workflow for building them from scratch.
-
Thanks
. It's so obvious really....let's chalk it up to a senior moment. -
I was just fiddling around with this and thought it worth dropping in.
This is the funny horn from a few pages back. Rendered in Twilight.

that speaker-bowl thingy is extremely well modelled well done box

Cheers, Oli, I'm just getting my beginner bits in before you break the mold.

lol don't know about that mate! great stuff! By break the mold I think you mean post some weird surrealist crap that doesn't really help anyone.

Q: How many surrealists does it take to change a light bulb?
A: Fish.
-
PMSL!
what lightbulb it's just a molten blob of glass?!
On a serious note (if there is such a thing)....is there a multi-face offset for curved surfaces?
So like Tools On Surface offset that you can apply to several faces at once?
