STEPutils

THIS PROJECT IS IN PLANNING STATE!

Abstract

STEPutils is a Python package to manage STEP model data.

The intention of this package is to build a simple document object model (DOM) for STEP model data like xml.etree.ElementTree for XML data. STEPutils could be used as import/export layer for CAD like application. The DOM has methods to traverse, create and delete object nodes but no further CAD-like functionality like translating, scaling or rotating objects, if you need that - you are looking for a CAD application like FreeCAD.

For more information about the STEP (ISO 10303) standard read this Wikipedia article.
