Turn an STP CAD model into an OBJ mesh. Curved surfaces are meshed finely enough to stay smooth, and the part keeps its real size and orientation.

What is STP?
STEP stores exact CAD geometry: true planes, cylinders, cones and freeform surfaces joined into solids. It is the standard way to move parts between CAD systems such as SolidWorks, Fusion 360, Inventor, CATIA and FreeCAD.
Full name
ISO 10303 (Standard for the Exchange of Product Data)
OBJ is a plain-text mesh format with optional texture coordinates and normals; materials and textures live in a companion .mtl file. It opens almost everywhere, from Blender to 3D printing software.
Full name
Wavefront OBJ
Type
Triangle mesh
Used in
Blender, Maya, 3ds Max, Cinema 4D, ZBrush, most slicers
Strength
Opens in nearly every 3D program and keeps textures through its .mtl file.
STP stores exact surfaces; OBJ needs triangles. We mesh each surface with a deviation of 0.05% of the part's size, which keeps holes and fillets smooth for printing and rendering.
Dimensions stay in the units of the original file, usually millimetres.
