3d Step Files Official

: Unlike mesh formats (like STL), STEP files use NURBS (Non-Uniform Rational B-Splines) to represent 3D geometry as exact mathematical curves rather than faceted triangles.

: Beyond geometry, they can store assembly hierarchies, part relationships, and sometimes metadata like material properties or tolerances. What are STEP files and how do you open them? - Adobe 3D Step Files

: Acts as a "bridge" between proprietary CAD systems like SOLIDWORKS (Dassault Systèmes), AutoCAD , and Autodesk Fusion 360 . : Unlike mesh formats (like STL), STEP files

: Files retain "solid" information, allowing users to modify faces and features in a new program, which is significantly easier than editing a raw mesh. : Unlike mesh formats (like STL)
