    I think the goal of most people to consume more program is facilitated not make life more difficult. Surely it's easy for fans of programming, but not for those who want to design something. Thanks anyway and good luck with your project.

    I used it a lot, it is a modeler and very precise but it works with the coordinates and you can not do organic shapes flowing like sweep or loft, does not work with surfaces and rendering is outdated. Instead of BRL-CAD I recommend Blender!

    It's not a CAD. It's CGS-geometry creator and ray tracer. It's most similar to Blender (or Maya on Window$) - tool for create foto-realistic image and movie.

    I've been using this package for almost a year for work purposes; it was required for the project. I'm a design engineer, and normally use CATIA for design purposes. BRL-CAD and CATIA are about as far apart on the cost spectrum as possible: free to most expensive package out there.... So maybe my perspective isn't fair, but at the same time and frustration are costly. With that out of the way, I'd say... I'd never recommend using BRL-CAD for design purposes. It is too difficult to make simple changes and understand your model. There is no simple way to add standard design features like fillets. I haven't tried to export to IGES or STEP (formats that you'd need to provide to a machine shop to make your part) but based on my experience trying to import those file formats, I wouldn't have confidence in the result. All in all, BRL-CAD is a neat project and I'm sure there is a use for it, but I would not recommend it for design purposes.
