About STEP
STEP (ISO 10303 STEP). The ISO standard for exchanging exact CAD solids. Faces are true curves, not triangles, so another CAD program can edit and dimension them.
Units: Explicit. Usually millimeters. Up axis: Z. Opens in Fusion, SolidWorks, Onshape, FreeCAD, and Inventor.
About OBJ
OBJ (Wavefront OBJ). A plain-text mesh format from Wavefront. Common in 3D art, scans, and game assets. Materials live in a separate .mtl file.
Units: None in the file. Usually meters or centimeters from 3D apps. Up axis: Y. Opens in Blender, Maya, 3ds Max, Cinema 4D, and most slicers.
