Parametric modeling, anyone?

Right. In SUbD I store all data in attributes in the definition. Currently, when the mesh is subdivided the control mesh is recreated entirely in attributes - even nested attributes. At the moment each limit-mesh entity has a unique ID that reference the ID of the control mesh so I can look up control mesh data. (I think that if a face is triangulated by autofold each new face will get a copy of the attributes.)
Sounds sofisticated. This gives me some ideas, thanks.

I do wish we could have a more generic way to create parametric tools in SketchUp though. A framework that could be used to kick start new creations easily without everyone reinventing the low level stuff all the time. But generic high performance frameworks are challenging to get right.
Yeah, that would be ultimate. Have you started yet ?

CEXT in that last screenshot just reference the Ruby C++ Extension that does the calculations.
Yes I was refering to a C-extension.

haha!
Well, one first need to understand the problem. Working on SUbD gives me some insight to that. Keeping an eye on this thread is also a good source of information.These types of extensions haven't been so in a great extent for SketchUp. So finding a good design pattern isn't easy. Will need some experimentation and trials and errors.

I first started using C extensions for Vertex Tools - in order to implement the soft selection feature with any reasonable performance. Scripted languages are usually slow for calculations - Ruby especially so.

Yeah I have the impression Ruby works fine for a while, but when you hit a wall it slows down exponentionally..
I'm looking into the C-stuff. Got some help now..

Have to say, this would be a dream come true for me. I've also been asking for something like this for quite a while, particularly for doing complex panelisation operations.
@jolran - I remember you telling me once that you were working on something off the back of hatchfaces; is that the propject that you are referring to in this topic? I can't seem to find any link to it though...Care to share??
Best of luck to you all!!

Hi Joel.
No, this is a different thing than the one I was working on back then.
There are no release yet, and no date set.You can PM me for specific questions/suggestions, should you wish to
