As a user of AutoEZ and its predecessor programs for years, I never stop being 
amazed at Dan's prowess.  I don't own, or see a personal need to own, Yagi 
Mechanical, so I won't be testing this capability.  I am curious though as to 
whether it can analyze and optimize a beer-can vertical:-)

As a kid I had one of these.  My dad provided an ample supply of materials.

So if you start a design in YM you can easily import the taper schedules into AutoEZ and assign variables for things like element tip coordinates and boom positions.  You can then use the AutoEZ optimizer to tweak the electrical properties (gain, pattern shape, SWR, etc) to your satisfaction.  When done you can then export back to YM format (*.stm file extension) and all the non-electrical properties (like tubing wall thicknesses, overlap amounts, yield stress, and density) will be preserved so you can pick up where you left off in the mechanical design.

In either case you can iterate back and forth between the two programs until you are happy with both the electrical and mechanical aspect of the model.

If you are a user of both AutoEZ and Yagi Mechanical and you have any very complex *.stm files you'd be willing to share please contact me off-list.  The more complex the *.stm file the better and any files you share will be kept strictly confidential.
