Today I gave the presentation on my FeLT project. Discussed all my
problems about exporting of one file format to another and certain
other problems. Told the whole workflow, all the possible approaches I
had in my mind. The discussion continued for about one hour.

At first, it seemed to be impossible. Then after the discussion and
suggestions the conclusion was to:
1)Build a parser between Coudrey and Dxf
2)To implement entities like circle, arc using collection of lines in FeLT.

Figuring out the things further 🙂
