Draft OCA

Description
Draft OCA is a software module used by the Std Open,  Std Import and  Std Export commands to handle the OCA file format.

The OCA file format is a community effort to create a free, simple and open CAD file format. OCA is largely based on the GCAD file format generated from gCAD3D. Both formats can be imported in FreeCAD, and the OCA files exported by FreeCAD can be opened in gCAD3D.
