In AutoCAD 2010 on the Output ribbon tab I selected the Share with Autodesk Seek and then selected a block I wanted to share. The block was When Ice Cream Goes Bad” from coworker Cliff Young.
It is a simple process where I upload and then I am presented with a page to add a content description, tags, etc. You do need to register for a new and FREE Autodesk Seek account.
Share and Share alike, and Seek and you shall find!
