Summary: .cnc, .nc files conversion

Initial Comment:
It would be great to have the conversion of the project
in files used by cnc machine.  A dream? maybe...or
maybe not.
I hope very much to have this software (brl),to make my
own project (rc model) and to give the files to a
friend of mine, who is able to use cnc machine. Result:
a perfect built rc model frame!

Message:
Given this feature request is technically provided via STL and DXF formats
(as they are a common CNC input format, I'm inclined to close this  feature
request out.

We're still heading in a direction that will support direct conversion of
our format to the gcode format, but that's still not likely going to happen
this year without someone working dedicated to the project (which at
present nobody is).  Until we're at least a year close to the feature being
easily feasible, it's too big a task to track here.  Revisiting this
tracker over and over keeps the idea in mind, but also consumes resources
to continually revisit.

I've added the item to our TODO file so we have a record of it.

Message:
We're quite a bit closer now that our new NURBS support is stabilizing, but
there are still a few critical components before we can (easily) tackle
CNC/gcode export.  Boolean evaluation of NURBS on NURBS geometry is one
such component.  After that is completed (unknown timeframe, but being
worked), it becomes trivially possible to output spline contours, which
would be a good start for a cnc export.

ok so not a direct one package solution but  
from what i gather you can export the brlcad to autocad dxf  
most of the cnc programs i have seen will import a autocad dxf 
format and it can then be saved as a cnc .nc flie  
 
you may be better importing to autocad or dxf editor to check 
scale and cutting paths before committing it to the cnc machine  
 
i have noted that doing the same with blender leaves some 
unwanted cutting paths  basicly it would do a good job but cut a 
big cross out at full depth making a pile of scrap because it 
keeps in the reference lines , so in the case of blender these 
would need to be edited out before machining   
 
hope that i have less truble with brlcad for this

Not so much of a dream.  There have been several groups interested in such
an 
application of BRL-CAD to cnc machining processes and other CAM interest
also. 
What we're in lack of right now is developer access/support to make the 
modifications.  When we get a developer that has access to a cnc machine
and 
that is interested in working more on this, we should be able to progress
this 
request forward more easily.  Folks interested in contributing to this are
more 
than welcome to join in and code up the modifications.  The foundations
for it are 
pretty much already in place from a holistic software package
perspective.
