Inside The GD&T Premium Reference Center, you will find over 275 GD&T Tips with PDFs, 88 with videos. There are an additional 160 educational videos, electronic versions of our GD&T Hierarchy Pocket Guides (1994, 2009, 2018), all ASME Y14.5 symbols, an easy-to-use search function, Y14.5 Standard references, case studies, Brown Bag sessions, and the SOLIDWORKS add-on. This robust reference center will help to answer questions related to GD&T and help users to refresh their knowledge of symbols not often used. With the SOLIDWORKS add-on, the reference center is available at your fingertips in a convenient drop-down menu within SOLIDWORKS. Our customers find the reference center (AKA GD&T help files) to be a valued resource both before and after GD&T training with Tec-Ease.
