TechDraw: Tipi di tratteggio
Descrizione
TechDraw ha due strumenti per il tratteggio:
- Tratteggio da modello (basato su tasselli)
- Tratteggio Geometrico (basato su linee).
Utilizzo
- Select a Face
- Depending on the need, press either TechDraw Hatch or TechDraw GeometricHatch icons.
Result: The face will be hatched initially using default values. Note: Edit the hatch properties to get the desired pattern.
Tratteggio da modello
Tratteggio da modello usa delle tessere di base SVG o bitmap per coprire la faccia selezionata.
Di solito le tessere SVG sono delle immagini di 64x64 pixel. Alcuni esempi sono disponibili su GitHub.
Come riempimento è possibile utilizzare qualsiasi file bitmap (png, jpeg, ecc.). I risultati migliori si ottengono con molte piccole immagini ripetute piuttosto che poche immagini grandi.
I riempimenti di tratteggio predefiniti possono essere specificati nelle Preferenze.
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:

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.
