	~~=Computer Aided Design (CAD)=~~

	Here are some open source options for CAD. Please add others if you know of any. We are looking for a cross platform program, preferably open source. It would be nice if it worked with our Mac OS X 10.3.9 laptops, and be cross platform for other collaborators, but we are using Linux now so anything for a PC with linux should work ok.

	~~'''[http://www.blender.org Blender]'''~~
	* Blender is an open-source 3D animation software.
	** It is poorly suited for CAD use. Operating Systems: All major platforms. Works ok for basic 3d design an prototyping but only makes meshes.

	~~'''[http://avocado-cad.sourceforge.net/ avoCADo]~~
	** Evaluation pending.

	~~'''[http://brlcad.org/ BRL-CAD]'''~~
	* BRL-CAD is a powerful cross-platform open source solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, image and signal-processing tools, a system performance analysis benchmark suite, libraries for robust geometric
	~~representation, with more than 20 years of active development. Operating Systems: All major platforms.~~
	** Evaluation pending.

	~~'''[http://CAELunix.org/ CAELinux]'''~~
	* "Based on the open-source CAE softwares Salomé, Code_Aster, Code_Saturne and OpenFOAM , you can load your CAD geometry in Salomé and start partitionning and meshing your problem in just 5 minutes. Then you can simulate incredibly complex physics with the open-source FE & CFD solvers Code_Aster, Code-Saturne, OpenFOAM & Elmer: non-linear thermo-mechanics, coupled fluid-structure dynamics, seismic / non-linear explicit dynamics, contacts, visco-plasticity, fluid dynamics, heat exchange, convection heat transfer and radiation, electro-magnetcis in other words nearly all physics problem can be addressed with the integrated solvers!! Then reload your results files in post-processing applications like Salomé, GMSH, Visit, or Paraview to visualize your data in 3D."
	** Hoping it can do CAD and is easy enough to use.

	~~'''[http://www.opencascade.org OpenCASCADE]'''~~
	* Open CASCADE Technology is software development platform freely available in open source. It includes components for 3D surface and solid modeling, visualization, data exchange and rapid application development. Operating Systems: Linux, Sun Sparc, or Windows.
	** Seems too 'clunky' without a better GUI.

	~~=Collaboration Discussions=~~

	~~==from Sam Rose==~~

	Blender is OK for sketching. But, not good for CAD/CAM programming, as it draws in vectors, and not in constructive solid geometry, which is what is needed to give you the details of dimensions of what you are drawing.

	OpenCascade does have CAD, and so does BRL-CAD. Much of the drawing done in both happens by way of command line input as opposed to computer mouse drawing. There is going to be a steep learning curve with any open source CAD (or even commercial CAD for that matter).

	~~While OpenCascade seems easier to me, the consensus among people working in open design is http://brlcad.org/~~

	~~What kind of computer are you going to be using (Mac, Linux?)~~

	I would say that it would be more than worth the time invested to learn http://brlcad.org/ this will put tremendous power to design into your hands. documentation is here http://brlcad.org/wiki/Main_Page and http://gpwiki.org/index.php/BRL-CAD:Tutorials tutorials can help.

	~~Also, get an IRC client and check yourself in to irc://irc.freenode.net/~~#brlcad if you run into questions you can ask the actual people that program it. Let them know who you are and your project and they will probably be interested in helping you. Mailing lists are here http://sourceforge.net/mail/?group_id=105292 but I do not follow them so do not know if they are currently active.

	Also, http://avocado-cad.wiki.sourceforge.net/Tutorial_CoffeeMug avaCADo is a very simple one that is based more on drawing (although with scant documentation). Yet, some evalution (using Ubuntu Intrepid Ibex 8.10) shows that it is capable of doing some pretty complex solid geometry operations (without all of the command line interface). Worth a try, and it runs on Mac too.

	~~----~~
	~~Marcin says:~~

	From a cursory view, AcoCADo appears to be best. We are looking for a simple drawing tool that has robust visualization features a la doing prototyping on the computer screen rather than in physical space, like Jeremy did on Sawmill wiki page with Blender. The goal is: if you can draw a design, you can see the details of how things fit together, and you can draw up a BOM and fabrication procedure for that. We're talking about basic modeling before one goes out to buy supplies.

	~~This is what we need badly right now for the OS movement in general.~~

	~~==Nick==~~

	Personally if I am going to go to the trouble of doing a model I'd like the program to have the capability of automatically putting out 2D manufacturing drawings and a BOM. This greatly streamlines the development process. I'm not certain if either of those two programs can do that?

	~~==From Chad==~~

	~~To respond to your request for open-source~~ CAD~~, see/explore the following links for an assortment of packages:~~

	~~If none found through those links suit your fancy, you may have to settle with a closed-source app for now - see the following:~~

	~~Open-source CAE - computational fluid dynamics, finite element analysis, electromagnetics, etc...a little farther down the line in product development, but you can bookmark it for now:~~

	~~=Development Discussions=~~

	~~Sam:~~

	Marcin, as we discussed in email: use BRL-CAD for actual CAD drawings. Blender is good for sketches, but BRL-CAD, or other solid geomtery modeling is needed for translation of designs to CAM. Perhaps more development of BRL-CAD is needed, or training for those using it. There is a learning curve for sure, but it is worth learning. Worth the time investment. Also, perhaps if we can build a set of stakeholders, we can raise some funds and get several developers involved in adding drawing capability to BRL-CAD or other solid geo model CAD, like OpenCascade (BRL-CAD developers are very receptive to supporting this type of development).

	Also, it is worth comparing RepRap with http://fabathome.org/wiki/index.php?title=Main_Page there is a consensus among some that fab@home is more robust/usable than RepRap. However, by the same token, RepRap could probably be made to be much better with some development. One of the problems with Fab@home is the software, which only runs on Windows http://fabathome.org/wiki/index.php?title=Fab@Home:Model_1_Software Fab@home seems to be a superior design, so it could be worthwhile to put some time and money towards development of open source, cross platform software to run it. This is something that I could look at developing this year.

	~~Also, on the software front, progress is being made on http://heybryan.org/mediawiki/index.php/Skdb~~

	~~Marcin:~~

	Sam and Nick, it is a good idea to be proactive as the project unfolds, and consider paying for open source development of the necessary, cross-platform solution - after we evalutate all options fully and then define our needs clearly. Please put the evaluation and needs info at
