Raster to Parametric Conversion |

R2P CAD Functional Architecture
This initiative investigated and demonstrated
the conversion of CALS Type I raster mechanical drawings to
parametric vector format, and to parametric 3D solid models
by leveraging KBSI’s "Vector to 3D" (3VD) technology.
Raster drawings consume storage space and network bandwidth,
have a finite resolution, often suffer from poor image quality,
and are expensive to maintain and edit. These limitations
impact electronic commerce, competitive reprocurement, and
maintenance.
None of the many raster-to-vector conversion
products currently available produces parametric vector drawings
(PVDs). In PVDs, the text and symbols are bi-directionally
associated with the drawing’s geometry, so a change to
a dimension will cause a change to the geometry of the drawing.
Conversely, in a vector drawing, a change to a dimension will
have no effect on the geometry.
In
fact, some raster-to-vector products convert the text into vectors,
wholly ignoring text legibility. In the R2P initiative, KBSI developed
technology that will allow further processing of drawings and convert
the vector file to a solid file format. As a commercial product,
this tool will enable billions of drawings to be inexpensively converted
to parametric CAD thus extending the usefulness of legacy data and
decreasing their maintenance costs.
