Here what has been done in Revision 124
1. Offset almost done. It works almost fine on not very complicated paths.
2. Offset have been integrated into lathe procedure. See the attachment.
What has to be done:
1. Offset bugfixing. (It might be not very important for lathe but if offset procedure gives two separate path it could lead to a problem - one of the paths could be not computed. It is not very important for the lathe extension because the offset distance should not be big, so the probability of separate loops is low.)
2. Export procedure
. I have not done it yet, but I think that almost all is ready for it. So I think I'll write it soon.
