The OVD format defines a schema for storing explicit drafting data which encompasses 2D "line like" entities in 2D and 3D space, as well as 3D wireframes, 3D polygons, and embedded solids. The goal is to provide a standard format for 2D and 3D drafting applications including import/export support from .dxf, .dwg, and .dgn formats.

This standard is still being defined and was previously referred to in the code and documentation as "Rhizopod" or "rzp". Many 2D entities are currently supported (including their 3D orientation) as illustrated by the dxf2rzp code.
