gracias por el aporte!!
saludos 
First timer, just exploring. 
I am working through your Precision Modeling Tutorial, although not with Blender 2.63. I had to download version 2.49 and then python 2.5.4 to do so. Looking at the Bmesh and other new features of 2.63 I am eager to see your next tutorial on the subject.
Thanks for your tutorials on building accurate engineering models. This is exactly why I started learning Blender a month ago. I quickly found out that there is not a lot of information on accurate engineering models which is what I would like to produce.
Can't wait for your new tutorial for ver 2.63.
Keep up the good work!
Thanks a lot for your great work on the 608 Bearing Tutorial. It was really easy to adept in Blender 2.62. I wasn't aware of the easy type-in method for precise modeling. Keep up the great work!!
Rob, always checking in on you. Learned a bunch with your precision guide and want to still say thanks.
I love your tutorials! Thanks for sharing your knowledge in an easy to learn way. It turns 3D modelling into joy.
I love the precission modelling tutorial in Blender! Very useful. And precise
.
Thank you very much 
Wonderful! Thank you for your contribution to the general wisdom of mankind. I partake joyfully. 
Being a veteran CAD user, I must admit that I only have been able to learn Blender through your legendary "Precision Modelling" tutorial. That said, I'll be waiting for your update on 2.5 patiently. Thanks, man!
