Drawing/it

Introduzione

In FreeCAD la parola "Drawing" (Disegno tecnico) viene normalmente utilizzata per fare riferimento a una proiezione 2D di un modello 3D. Generalmente viene creato con l'ambiente TechDraw .

Utilizzo

1. Iniziare con un modello 3D già creato, creato ad esempio con PartDesign. In realtà, funziona con qualsiasi oggetto che ha una Forma, inclusi gli oggetti 2D.
2. Passare in TechDraw.
3. Premere il pulsante File:TechDraw New Default.svg Nuovo disegno standard o File:TechDraw New Pick.svg Nuovo disegno da modello per creare una pagina.
4. Selezionare il modello esistente, quindi premere Vista di oggetto o File:TechDraw NewProjGroup.svg Gruppo di proiezioni.
5. Viene creata una proiezione 2D sulla pagina. Ora è possibile regolare le sue proprietà, ad esempio DatiScala, DatiRotazione, e DatiDirezione.
6. Quando il disegno è pronto, è possibile premere File:TechDraw SaveSVG.svg Esporta pagina in SVG, File:TechDraw SaveDXF.svg Esporta pagina in DXF, o usare Esporta, per esportare la pagina in formato SVG, DXF o PDF per un ulteriore utilizzo in un altro software o per la stampa.

Note

In informal usage, a "Drawing" may be any geometrical figure that is visible in the 3D view, and thus its concept may be confused with that of "Body", "Part", or "model".

However, when more precision is required, the distinction must be made.

• A "Body" (PartDesign Body) is an object derived from a Part Feature (Part::Feature class), created with the PartDesign Workbench.
• A "Part" (App Part) is used to group several "Bodies" to form an assembly.
• A "Drawing" is a 2D projection of a "Body" or a "Part".
• A "Drawing" may also be created with the Drawing Workbench. However, since this workbench became obsolete in 0.17, you should prefer TechDraw Workbench instead.
