Popis

Management FreeCADu na dálku, žádné přímé editování modelu (pro tento účel viz. Rozšíření).

Pro posílání příkazů na tento server, potřebujete klienta. Přiložen je jednoduchý pythonový nástroj pro příkazovou řádku, jako referenční implementace.

Toto vám umožní globálně (ale stále v prostoru serveru, ne FreeCADu jako takového) vybrat :

• dokument
• objekt
• tabulku
• souborovou cestu (hlavně pro export)

Následující operace mohou vyžadovat dokument/objekt/tabulku/souborovou cestu

(většina z těchto argumenů je nepovinná)

• zadaná hodota je použita nejdříve
• pak globální
• a nakonec aktivní/defaultní výběr ve FreeCADu jako takovém

např.:

• můžete získat seznam objektů v aktivním dokumentu příkazem 'O'
• můžete také získat seznam objektů v konkrétním dokumentu příkazem 'Okonkretni_dokument'

(seznam všech dokumentů vrátí příkaz 'D')

Také umožňuje získat seznam :

• otevřených dokumentů
• objektů s jejich jménem (Name) a označením (Label)
• buňěk v tabulce s jejich hodnotami

A můžete dokonce :

• získat hodnotu buňky
• nastavit hodnotu buňky
• přepočítat (potřeba po úpravě hodnot buňek)
• exportovat
