Sorry for the late reply,but the internet connection was broken yesterday evening
and just got fixed an hour ago.
Glad to see that you could solve the smoothing problem i was refering to yourself.
Most likely it was the smooth object function i'd say.
If you want to model more geometrical stuff you should consider using wings3d
instead of blender though.I've tried both and wings is definitely better for geo-
metrical things.
Keep it up,J.
