Think3 Inc, the Italian mechanical computer-aided-design software house now run by ex-Cadence Design Inc CEO Joe Costello, intends to reveal its new business plan at a press conference this Wednesday. Think3, originally called Cad.Lab Inc, recently won $17.5m in second-round venture funding, plus an investment from Intel Corp (CI NO 3,567). It is preparing to launch a 3D design tool aimed at the low-end of the market, and also plans to launch the CAD-CAM industry’s first portal web site.
