how much modelling experience do you have ?
Lots of modeling experience, but like most things, it may not be in the relevant areas…
Mostly my past and current modeling is “cad-like,” so deals with more precision shapes and known (or relatively known) dimensions.
what the final data used for ?
Most of this stuff is primarily intended for archviz/productviz. That said, I am designing some board games and do, actually, need to produce physical things sometimes, too.
start modelling (nurbs or subd) and ask as soon as you struggle with a more detailed challenge in your precise design ?
What I’m trying to avoid, where I can, is getting 80% of the way through a modeling exercise (or tutorial) only to find out I should have done it another way
maybe google for:
how to model a pillow / cushion in rhino…
you will find both - nurbs and subd approaches.
if you really need to visualise all those detailed crinkles from the leather - at some stage you will need some texture / bump-map techniques maybe combined with some mesh based sculpting (blender or zBrush)
you may also google for cloth modifier / cloth simulation (blender, 3dmax, …)
Thanks - yeah, I’m planning on sculpting the wrinkle details in Blender.
I wasn’t thinking about modeling the cushions using any cloth modifiers, though I’ve been trying out the demo of Marvelous Designer for some other purposes. I’ve used Blender to make basic “inflated” pillows, but not anything with much “soft” structure. I do have some add-ons…
