You're welcome,eco, - both excellent bits of s/w there, and would be complemented by my suggestion, rather than being made redundant or anything stupid like that! It's just that the workflow with SDS modellers is really totally different to 'normal' 3d apps ( -I've also got Rhino + others) and you'll wonder why you 'struggled' with the traditional methods - for the types of models that sds is good at making / producing. wings also imports/exports 3ds,Obj and Ndo files so you should be able to get the best of everything? Only cause for complaint I've got is lack of talent! btw - to install wings you need to d/l Erlang (about 23Mb) first - if you're on a dial up (like me) with time cut-off, don't worry, it's cumulative, so if link breaks can pickup from where left off - this 23Mb is a once only install, app. is about 890k, so only need to d/l this each time there's an upgade - presently about once a week or so Checkout the forum first (link on wings site), and see what you think - no-ones twisting arms here? In case you're wondering, no, I've not got shares in it! (although together with many other people, am contributing a little to its development, where possible) pp
