The STEP file browser, at http://spri.kshell.com will read a STEP file and deliver X3D models of the geometry in the file. If the STEP file contains NURBS surfaces then the X3D file will render those as NurbsPatchSurface or NurbsTrimmedSurface; and many other curved surfaces in the STEP file geometry are delivered that way as well.

See http://www.kshell.com/pages/x3d_cad/ for a description of how to upload STEP files and get X3D back. The content of that page is out-of-date, the latest versions of the Octaga browser do not support NURBS surfaces as well as the version 2 of Octage Player did.

Encouraging and enabling support for NURBS surfaces by browsers and X3DOM is a major interest of the X3D-CAD group; see http://www.web3d.org/wiki/index.php/X3D_CAD.
