Thanks Crescent. I got all the magazines - which has Truespace 3, Amapi 3D 5.15 and Lightwave Discovery Edition. I tried installing them all. Noticed that Amapi 3D v5.15 does not have WinXP version but the interface seems the least intimidating. The Lightwave one freaked me out at first glance. Is it worth it upgrading the Truespace one or the Amapi 3D one ?
