The Tec-Ease GD&T Challenge

Tec-Ease invites you to participate in our GD&T Challenge. Periodically we will present a new GD&T Challenge question. When you have the answer, or think you do, submit it to challenge@tec-ease.com. All correct answers will be put into a drawing to win a prize. Approximately a month after we post the question, we will conduct a free Brown Bag Session discussing the challenge question and solution. Participants will be able to submit questions to be answered by the presenter. Everyone is welcome to attend this free session, whether you submitted an answer or not.
