I use a mac (G5)
I have been playing with extrude along path but the methodology escapes me, there is a tutorial on this in the tutorials thread but it is an unplayable .AVI file (I can play most .AVI files but not this one - it's a Windows world
I have achieved some success since posting and have manage to make a 'template' sail which can be copied and modified. I'll continue until the "voila!" moment.
Thanks for your input.
