Hi MDC,
This is great. :) Thank you for your detailed explanations because
now I can understand the concepts behind the tools that are used to
make this model.
I will give it another try with AMAPI 6, keeping your points in mind.
I know my hand manipulated extrude technique may take some time
because I have basically used extrude for lathing rather than creating
hand-made bevels up until now.
I have had my eyes on AMAPI 7 for a while, but my family inheritance
has not caught up with me yet. ;) Actually, I just upgraded to AMAPI
6 last December, but I hope that graduating to version 7 will not be
too far off.
Cheers.
