A developer version of BRL-CAD's geometry converter plugin for Pro/
ENGINEER is now available . The ProE-BRL plugin is a production
exporter that has been developed over the years as a means to import
geometry into BRL-CAD from Pro/ENGINEER (aka Pro/E).
Please note that this is a developer version of ProE-BRL. While the
converter has been in production use for some time, this is a
developer compilation that is being provided "as-is" without any
release testing. Also noted in the posted README.txt file ,
there is no guarantee that the plugin will work within your
environment. The installation and setup require familiarity with Pro/
E and Pro/E plugins that are beyond our support scope, but there are
some installation notes provided. The included INSTALL.txt file may
be of assistance.
This binary release is being provided with the hopes that it will
work and be useful to those exporting geometry from Pro/E into BRL-
CAD . You are, however, strongly encouraged to make backups of
your data before using the exporter within a production environment.
Particularly for users that have been unable to compile from source
code, there are 32-bit and 64-bit Windows versions of the plugin
available for Pro/E Wildfire 3.0, 4.0, and 5.0 in our Sourceforge
 Screenshot of ProE-BRL running within Pro/ENGINEER:
The plugin runs within Pro/E and exports geometry in polygonal format
for use with BRL-CAD. Geometry is written into our ".asc" ASCII
format which can be converted to our ".g" binary format with "asc2g"
or or by sourcing the file into mged with the "source" command.
Note that the prescribed workflow with the ProE-BRL converter is a
fundamentally lossy process that changes the representation format of
the original geometry. The conversion to polygonal mesh geometry can
introduce new overlaps on valid geometry or even fail outright
(within Pro/E) if there are modeling errors. This time-intensive
process is being deprecated by our active BREP/NURBS development effort.
We are in the process of developing and validating a new method using
the ISO STEP format and BREP/NURBS geometry as a replacement
workflow. This new process faithfully preserves geometry in native
CAD format so no new overlaps, topology changes, or modeling errors
are introduced. Initial results are looking great with substantial
time savings being observed (both during conversion and analysis).
More details about this improved workflow will be announced as
development progresses and our validation process is completed.
If you are successfully able to install and use the converter, feel
free to let us know on the forums or mailing list. If it doesn't
work, that's not acceptable but please do not let us know for this
developer release. A screenshot of what the plugin GUI looks like is
