'facetize' command do not run for brep objects. I tried as suggested by you first by running brep command for an entity say rcc. It created 'cyl1_brep' object. When run facetize on cyl1_brep, it says: nmg_booltree_leaf_tess(cyl1_brep): tessellation failure _db_walk_subtree() FAIL on '/cyl1_brep' facetize: tessellating primitives with tolerances a=0, r=0.01, n=0 facetize: no resulting region, aborting But facetize successfully run on implicit primitive cyl1, showing following message: facetize: tessellating primitives with tolerances a=0, r=0.01, n=0 facetize: evaluating boolean expressions facetize: cyl1 facetize: converting to BOT format As such I couldn't run bot_dump inside from MGED. First I tried simply running "bot" within MGED and from usage message, I run "bot get faces cyl1Faces" and got the total number of faces of object. But from brlman page of bot_dump, finally I exported cyl1Faces bot to different text formats. But point that worth to be noted is that facetize command do not run on brep objects. > Alternatively, you could export the brep directly and figure out how to > visualize NURBS geometry directly if you find a web technology that supports > them. I will share shortly whatever I find. -- Harmanpreet Singh Blog: http://singhharman.wordpress.com/ ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ BRL-CAD Developer mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/brlcad-devel
