I'm pretty new to 3DGC and i need some help to create a shape. does anyone know how to make this?

>> No.502299

with your hand :)

>> No.502301

>>502298
Yeah, why do you ask?

>> No.502302

just for revision from past papers. I have been trying to find how to do this shape for about 20 minutes. I can't seem to find out how to make that triangle shape though.

>> No.502303

i know

Ahh i understand it more now but the program that I am using is auto desk inventor professional and I don't think you can do that in inventor.

Made it in Catia, Anon, the procedure must be simmilar

Made this sketch

>all those triangles

wtf is wrong with you

>> No.504118

The only triangles in that image are at the end caps of those silver pins... And so long as you create an edgeloop at the top of it, it's fine to have it converge to triangles.

Ah ok, no wonder you're going nowhere in life.

Lmao, if you're not a troll, that's really sad. Please, point out where there are triangles other than the end-caps on the silver part. The pole at the center of the mesh is all quads.

The reasons you don't use triangles is to maintain edge-flow, allow for proper deformations if you will be deforming, and to allow the smoothing algorithm to smooth properly. If your triangles lay on a perfectly flat, hard-surface, then they cause no issues, you could have a giant 24 sided n-gon there if you want and it wouldn't matter at all so long as you surround it by an extra edge-loop. He doesn't have any supporting loops in for smoothing yet, so this is all irrelevant, until he plans to smooth it and add the supporting loops to do that, those triangles are perfectly fine.
