> It's designed (I think) mostly for people to make digital clothing for their Second Life avatars
Surely this tool isn't just for Second Life? Why would you need to produce panel layups for a synthetic model?
No, I think it's genuinely for First Life applications. See some of the demo images: modelled garment vs real garment (on the other hand, they could be attempting to reverse-engineer existing garments into models for 2nd Life...)
I suspect the ability to do tensioned surfaces 'come for free' as part of the clothing drape analysis. It's useful to know where stressed seams are, even in clothing.
The Overview page gives a good, well... overview, discussing pattern block generation, drape analysis, material properties (let's hope it copes with anisotropic properties, e.g. warp/weft/bias).
I notice the $99 personal edition doesn't include 3D data sales. I'm not sure what that means... Does it mean all the lovely draping and analysis isn't provided?
Andrew, my comment about the title was an expression of regret, not complaint; I think this software is potentially very useful to a very wide range of MYOG types. Thanks for clarifying that it's MD doing the stress analysis. Your tunnel tent, did it use a circular hoop model?
The question about the teepee, and boundary effects reminds me of methods I'd considered for previous thoughts at how to do stress analysis, and that is to provide a fixed edge as part of the model; like the curved hoop in the tunnel tent. e.g. insert a catenary curve boundary element to the 'avatar'. Or insert panels that won't be fitted in the final design (e.g. the teepee would have no door opening). They are workarounds that won't be 100% accurate, but they're likely to be better than nothing.
Modelling guyropes should be unnecessary, I think, provided your guys are inelastic; you'd specify the guy attachment points as fixed locations. Oh, hang on... ideally, you'd model the guying point on the ground, and model the guy as a inelastic bar, but with freedom to rotate about the guying point. You might even model the guy as a bungee loop (for ground pegging points, that is, not upper tent body guylines).
The 30 days from download is holding me back at the moment, as I won't be free for a while...
