Sorry, I can't find spare time in the pas= t year to create this tutorial.
In the secondary school (where I'm a t= eacher) I tried out the FreeCAD
with my pupils. It's not so good so fa= r and hasn't such rendering
capability as BRL-CAD has. However, BRL-CA= D is not for this age-group
too.

An interesting observation...  I've actua= lly used BRL-CAD with secondary school students on a number of occasi= ons over the years and have had a different experience.  Since t= hey've never seen a commercial CAD package, they're able to learn our= interface much more quickly and easily without preconceptions. = Especially for teaching basic modeling concepts, I didn't think we w= ere doing that bad even with our learning curve.


Can you think of a specifi= c way we can improve?  Do you think a shorter tutorial would be = most helpful?

Our participation in the GCI progra= m would also seem to indicate it's at least possible.  Those 13-17 ye= ar old students did a truly fantastic job making models, documentatio= n, and even code modifications.  They just need to be told where = ;to go and have an example/tutorial to follow.  We have a backlog of = work there to integrate which we'll be back on after our upcoming rel= ease is posted!
