Barry's Class A tutorial: align a blend curve for trim convert

[KathyKathy]

Hi @BarryKimball  Excuse me for another question on your Class A Training Tutorial. 

In the part 3.13 (19:08), you aligned the blend curve's CV to the fillet surface hulls first, and then used the aligned blend curve to trim-convert the fillet surface.  It seems to be ok to use the original blend curve directly for trim converting. Why did you try to align the blend curve first? Is this alignment essential? Thank you!

thanks for your question... at 19:28 I explain the reason why it is NOT ok to use the original blend curve.

Hi @BarryKimball  Thank you so much for your quick reply! Oh, yes you've explained it in detail. I think I did not understand it well last time when I went through the tutorial. Let me examine it again! Thank you!
