The company’s Web site, www.heli-cal.com/cm/products/flexible-couplings/home.html, lets users view and download 3D CAD models of standard curved-beam flexible-shaft couplings. This capability is a result of an ongoing partnership with Trace Parts, an online library of parametric components for 2D/3D CAD assemblies.
