Webbed dish 4285 sub-part

[Willy Tschager]

Hey, thanks!
On first reading a couple hours ago I was like "WTF is he talking about?!", I'm really not versed in this stuff but I read it again, trying to follow your chain of thought and I'm definitely getting there. However, I'm not quite sure what's your advice about. Correcting the coplanarity issues by calculating the intersection points? That could help, I guess!
I was approaching the thing in quite a naive way: I manually subdivided the 32 segment original: the inner ring's big segment into two (getting a 64 segment circle) and dividing the outer ring by 3 achieving a 96 segment circle. The radial's vertexes were "fixed" in my mind I just draw triangles and modified the quad's coordinate to that vertex that I considered "fixed".
If I may ask a question: what's the meta now? Do you still use rect.dat files, or is it okay to just draw quads and add lines? I can certainly handle that quite easy, tbh, but I have no idea how to handle rect.dat references. And for extra honesty here: I'm satisfied with the renders I got, I only uploaded this file here for the sake of community if anyone ever want to touch up this sub-part. 
If I go deep should I:
- try to recreate the part OR
- just correct the coplanarity issues?

Hi,

It is perfectly fine if you leave the part as and where it is now - but you could also see it as a challenge or a chance to learn new things. We are not new to guiding people through this process:

As for the "Rects," you asked the wrong person: I do not like or use them, and I’ve stopped reviewing parts that contain them. Nowadays, rects are in our code because of "Rectifier." No one would or could calculate a rect (especially a rotated one) manually if wasn't a program that does it for you. I think rects are fine on a standard grid to help with authoring, but they shouldn’t be in the final code.

If you want to continue with your work: Redesign the joints where the rings meet the spoke using the 96-piece part and the intersection I posted above and come back when you're done.
