Good Mornin' all you Techno's!

Gonna be heading to San Diego this afternoon to visit a potential
customer, hope the weather is as nice as it usually is out there.

I have a question about ODB++ files. My stencil vendor called me
a few days ago after I had sent them a ODB++ file to get the stencil
made for a board. They said for some reason things didn't look right
at  a few locations...specifically at some TO 252/268 locations.

The two pads for the leads were overlaping the one big area for the
base of the footprint. I didn't have an actual board yet, so I couldn't
verify the dimensions of everything.

I have two different viewers here that are capable of viewing ODB++
files, Autoview SolidModel by Cimmetry Systems, and a Valor Universal
Viewer, of course by Valor.

I discovered that things can look different depending on what you use
to view ODB++ files. Take a look at; "Autoview SolidModel" and Valor
Universal Viewer" on my page at; http://www.stevezeva.homestead.com

Look at the way the footprint looks for Q2, Q3, Q4, and Q5.

I just got the fab yesterday afternoon and confirmed that the image that I
see with the Valor Universal Viewer is correct. Why does different software
display ODB++ files so differently?

Kind regards,
