Gentlemen, My assessment, USD $.02, is this is a fine piece of software. The US Army has been developing this for more than 20 years. I think you can probably resolve a few library problems and get it working. My experience is this is not dependency hell. If you want to solid model prismatic parts this is a very good tool. Exporting geometry is somewhat limited. I haven't checked for a year or so but in my experience this is a text based modeler. It could be quite a learning curve for someone used to a graphics (point and click) interface. Unless some recent development has added some surfacing capability most CAM programmers will find this package sorely lacking in geometry creation. Manifold geometry does not exist in the BRLCAD world. Full solid models are the only option. Primitive entities are the only option. Surface types are limited. This is great for analysis. Not so great for machining in most of the CAM systems. This package was written for ballistic analysis not CAM work. I will admit to liking the text based interface (I am an APT programmer) and I will admit to not knowing/using BRLCAD enough to speak with authority. This opinion is based on my experience downloading, running the tutorial and building a few solid models. YMMV What is your desired product of a CAD system? This could very well be the best tool for your desired use. Probably not. thanks Stuart

Money and goods are clearly not the same things, but are exactly opposite things. Goods are wealth which you have, while money is a claim on wealth which you do not have. Goods are an asset; Money is a debt. If goods are wealth; money is clearly not wealth, it is negative wealth, maybe even anti-wealth. – Quigley, Tragedy and Hope, pg. 44 (emphasis added) ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
