Beau Turner has unveiled the Triple D Design Wiki, a resource to allow the architectural/engineering community to share their experience using 3D Design software. You can read more about this in his blog, or jump right into the Triple D Design Wiki.
Phase I provides an area for Architectural Desktop users to pool their knowledge. A future Phase II is planned, to suppport Revit Building users.
Here is another opportunity to tap into the accumulated knowledge of the ADT user community, as well as to contribute to it. If you have mastered some part of ADT, share that hard-earned knowledge with others, and learn something new from someone else.
