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.

The next update to AutoEZ will have the ability to both read and write Yagi
Mechanical (YM) format files. 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.
On the other hand, if you start out in AutoEZ you can create a YM file and
AutoEZ will assign typical default non-electrical properties for each taper
section when building the *.stm file. 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.
At the moment I'm still debugging this new feature and I'm looking for *.stm
files for use as test cases. 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.
The next AutoEZ update will also be able to import Yagi Optimizer (YO) files
but I already have hundreds of those that I've gathered from around the Web.
Thanks.
