Hello, I'm JohnBlackburne. I wanted to let you know that I removed one or more external links you added to the page Geometric dimensioning and tolerancing, because they seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thank you.

Please stop adding inappropriate external links to Wikipedia, as you did to Concentric. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you may be blocked from editing Wikipedia.
