I just joined this forum and I've seen many posts from people looking for Visio shapes. The site www.shapesource.com offers hundreds of stencils for an array of uses. Many are free, others are for purchase. We also have a Visio add-on for dynamically counting items in a Visio drawing and generating bill of materials or estimates in Excel. It's currently in use by companies for network equipment, parts supply cabinets, security systems, fire and safety, and modular furniture.
