Bentley Systems Inc., Exton, Pa., released an information model-based product for electrical substation design. Bentley Substation V8i integrates two- and three-dimensional tools and can shift from schematic line drawings to 3-D object views on the fly. Reports and bills-of-materials can be generated from the data as required. It draws on a database of more than 2 million electrical parts. Three-D modeling helps optimize site layout, integrates with Bentley’s Project Wise system and is priced at $15,000 a seat.
