# Wymiary odpowiadaja plikom STL/DXF z tego samego katalogu.

# Uruchomienie (FreeCAD >= 0.20, darmowy, freecad.org):
#   freecadcmd freecad-eksport.py        (bez GUI)
# albo w GUI FreeCAD: Makro -> wykonaj ten plik.
# Wynik: po jednym pliku .step na element, w katalogu biezacym.

# Kazdy element to bryla obrotowa: zamkniety profil (x, r) obracany
# 360 stopni wokol osi X. Gwinty NIE sa modelowane (walec o srednicy
# nominalnej) - oznaczenie gwintu jest na rysunkach i w wyliczeniach.
