TechDraw Hatching/it

Modelli di squadrature

Dimensionamento e tolleranza geometrica

TechDraw

Descrizione

TechDraw ha due strumenti per il tratteggio:

• Tratteggio da modello (basato su tasselli)
• Tratteggio geometrico (basato su linee).

Image based hatch

Tratteggio da modello

Il Tratteggio da modello utilizza delle tessere di base SVG o bitmap per coprire la faccia selezionata.

Di solito le tessere SVG sono delle immagini di 64x64 pixel. Tutti i file di pattern forniti con FreeCAD sono disponibili su GitHub.

Bitmap based patterns are displayed with a fixed resolution of 10 px/mm relative to the page.

I riempimenti di tratteggio predefiniti possono essere specificati nelle Preferenze.

Geometric hatch

Tratteggio geometrico

Il Tratteggio geometrico genera un modello di linee basato su una specifica letta da un file. Questo file è generalmente compatibile con il formato PAT di AutoDesk® ampiamente utilizzato. Una piccola selezione di modelli è inclusa nel file FCPAT.pat:

; standard PAT patterns

*Square, square grid, Solid, 5.0 mm separation

*Horizontal5, horizontal lines, Solid 5.0 separation

*Vertical5, vertical lines, Solid, 5.0 separation

Se si dispone dell'autorizzazione alla scrittura è possibile aggiungere i propri schemi in FCPAT.pat, oppure è possibile creare il proprio file *.pat e indicarlo nelle Preferenze.

Percorso del file PAT

Il file FCPAT.pat può essere trovato nel seguente percorso:

• Windows: C:\Program Files\FreeCAD\data\Mod\TechDraw\PAT\
• Mac: /Applications/FreeCAD.app/Contents/Mod/TechDraw/PAT/
• Linux: /usr/share/freecad/Mod/TechDraw/PAT/
  • freecad-daily PPA: /usr/share/freecad-daily/Mod/TechDraw/PAT/
