STEP (.step, .stp)

New in 14[Experimental]

Import and Export fully support the STEP file format.

Background & Context

- MIME type: model/step
- STEP ISO is the standard for representation and exchange of product manufacturing information.
- 3D geometry format.
- Commonly used for representing 3D models for computer-aided design.
- ASCII format.
- Stores a 3D object, including a solid, as a surface formed by a collection of adjacent triangles.

Import & Export

Import["file.step"] imports a STEP file as a graphics object representing the surface.
Import["file.step",elem] imports the specified element from a STEP file.
The import format can be specified with Import["file","STEP"] or Import["file",{"STEP",elem,…}].
Export["file.step",expr] exports a 3D graphics object to a STEP file. The expr can be any region that is ConstantRegionQ or a Graphics or Graphics3D object.
The export format can be specified with Export["file",expr,"STEP"] or Export["file",expr,{"STEP",opt₁->val₁,…}].
See the following reference pages for full general information:

	Import, Export	import from or export to a file
	CloudImport, CloudExport	import from or export to a cloud object
	ImportString, ExportString	import from or export to a string
	ImportByteArray, ExportByteArray	import from or export to a byte array

Import Elements

General Import elements:
"Elements" list of elements and options available in this file

"Summary" summary of the file

"Rules" list of rules for all available elements
Graphics representation elements:

	"Graphics3D"	OBJ file represented as a Graphics3D object
	"GraphicsComplex"	OBJ file as a GraphicsComplex object
	"PolygonObjects"	list of polygon primitives given in absolute coordinates

Import and Export use the "Graphics3D" element by default for STEP files.
