Dear David,
Very nice to know that the Femm users now have a Nov. 10th
release of Femm. I would like to stick my finger in the cake if you
do allow me to do so. One of our students had problems when
importing in Femm dxf files from newer versions of AUTOCAD,
they found that with versions R12 and below of AUTOCAD, Femm
is importing the dxf files nicely, but when using Autocad R14 and
above the Femm program refuses to import the files. Autocad has
something new that Femm program doesn't like.
Anyone out there had such experience?
Sorry for my ignorance, but I leave that for the programming
wizards to discover what is going on.
With my regards and thanks for any comments concerning this
matter,
Sincerely,
