A new version of BRL-CAD's geometry converter plugin for
Pro/ENGINEER is now available for download . The ProE-BRL plugin is a
production exporter that has been developed over the years as a means
of importing geometry into BRL-CAD from Pro/ENGINEER. This update of the plugin for the Windows platform supports
Wildfire 4 (64-bit), Wildfire 5 (64-bit), and Creo (32-bit and
64-bit). The plugin will work on other platforms, but will have to be
compiled from a source distribution. This binary release is once again being
provided with the hopes that it will be useful and should fix problems loading the plugin on Vista.
The way the converter works, it asks Pro/ENGINEER to convert geometry
from their internal boundary representation format into a facetized polygonal
which is then imported into BRL-CAD as a collection of Bag o' Triangles
(BoT) geometry. Needless to say, that process can (and does) fail
within Pro/E before even getting to BRL-CAD, so the ProE-BRL plugin
attempts to coerce a conversion. It iteratively adjusts tolerances
(down to specified minimums) until geometry is processed successfully
and provides various options for reporting when conversion to polygonal
mesh fails. While that method of import is rather suboptimal , it's
often a convenient method of importing models into BRL-CAD if you work
extensively with Pro/ENGINEER.
