It's always hard when we lose community members. I've gone through this more times than I care to recall, and it never gets any easier.
Our Autodesk Support family paid close attention to Sinc, and referred users to some of his articles regularly. Sinc knew surveying and Civil 3D like no one else, and the industry will mourn our loss. I feel as if we learned more from Sinc than he ever learned from us. I met him in Las Vegas a few years back and really had a great time talking to him and finally putting a face and voice to the online persona.
Jeff - thank you for keeping me updated via email since I don't get the opportunity to visit this forum that much anymore. I've kept our team informed and we are all reeling from the news this morning. I'm glad that I got to talk with you in Las Vegas and sign the card - I hope he got some happiness from reading the well wishes from his fans.
Peace be with us all.
