ATT Calculator


Why would any software company give away software for free?

We want to increase our name recognition in the tube fabrication market, and I feel that this is the best way to do it. This program can be thought of as our electronic "business card." So, feel free to copy the software and pass it along to your friends and colleagues. Please let them know that this software is available for downloading without charge.

The calculator contains hard-to-find math tools often used by tube fabrication engineers. We plan to add new features to this program occasionally, so you may want to check our website periodically for the ATT Calculator version. Every time we add new features, we will also increase the version number so you can know if you need to perform a new download. We want your suggestions for future versions, so please let us know if you have ideas for new features.

To COPY a value, select that value using the mouse or the shift key and then press Ctrl-C.

To PASTE a value to a box, select the edit box where the value is to be placed and then press Ctrl-V.
