IFC Versions


The STEP Tools® libraries read and write the latest IFC4x3, 4x2, 4x1, IFC4 or IFC2x3 definitions as C++ classes for fast programming on any IFC model. Our meshing functions transform IFC geometry for use with OpenGL, WebGL, additive manufacturing, or analysis.

The mesher supports geometry like extruded profiles, plus IFC4 manifold solid breps with trimmed surfaces. Many extension functions simplify work with with IFC axis placements, units, and other data.
