Description
Descrizione
Lo strumento Tasca scava un solido estrudendo uno schizzo, o una faccia di un solido, in un percorso rettilineo e sottraendolo dal solido.
A sinistra lo schizzo del profilo (A) è mappato sulla faccia superiore del solido di base (B); a destra il risultato della tasca.
Usage
Utilizzo
- Selezionare lo schizzo da usare per lo scavo.
- Lo schizzo selezionato deve essere mappato su una faccia planare di un solido esistente o su un oggetto Part Design, altrimenti si riceve un messaggio di errore. versione 0.16 e precedenti
- Premere il pulsante
Pocket. - Impostare i parametri Pocket (vedere successiva sezione).
- Cliccare OK.
Opzioni
When creating a pocket, or after double-clicking an existing pocket in the Tree view, the Pocket parameters task panel is shown. It offers the following settings:
Type
Type offers five different ways of specifying the length of the pocket:
Dimension
Quando si crea una cavità, la finestra di dialogo Parametri Tasca offre quattro diversi modi per specificare la lunghezza (profondità) di estrusione dello scavo:
Quota
Inserire un valore numerico per la profondità della tasca. La direzione di default per l'estrusione è verso l'interno del supporto. Le estrusioni si realizzano normali al piano di definizione dello schizzo.
Le quote negative non sono possibili. Al suo posto usare invece l'opzione Invertita.
Fino al primo
La tasca viene prodotta fino alla prima faccia del supporto nella direzione di estrusione. In altre parole, viene asportato tutto il materiale fino a raggiungere uno spazio vuoto.
Attraverso tutto
La tasca scava attraverso tutto il materiale nella direzione di estrusione. Quando si attiva l'opzione Simmetrico al piano lo scavo viene prodotto attraverso tutto il materiale in entrambe le direzioni.
Fino alla faccia
La tasca si estrude fino a una faccia del supporto che può essere scelta facendo clic su di essa.
Due dimensioni
Questo permette di inserire una seconda lunghezza per estendere la tasca nella direzione opposta (nel supporto). Anche questa può essere cambiata spuntando l'opzione Invertita. versione 0.17 e superiori
Through all
The pocket will extend up to the last face of the support it encounters in its direction. With the option Symmetric to plane the pocket will cut through all material in both directions. Note that for technical reasons, Through All is actually a 10 meter deep pocket. If you need deeper pockets, use the type Dimension.
To first
The pocket will extend up to the first face of the support it encounters in its direction.
Up to face
The pocket will extend up to a face. Press the Select face button and select a face or a datum plane from the Body.
Two dimensions
This allows to enter a second length in which the pocket should extend in the opposite direction. The directions can be switched by checking the Reversed option.
Up to shape
introduced in version 1.0: The pocket will extend up to the selected shape. Optionally press the Select shape button and select a shape. Leave the Select all faces checkbox enabled or disable it, press the Select button and select the faces up to which the pocket should be created.
Offset to face
Offset from face at which the pocket will end. This option is only available if Type is Through all, To first or Up to face.
Length
Defines the length of the pocket. This option is only available if Type is Dimension or Two dimensions. The length is measured along the direction vector, or along the normal of the sketch or face. Negative values are not possible. Use the Reversed option instead.
2nd length
Defines the length of the pocket in the opposite direction. This option is only available if Type is Two dimensions.
Symmetric to plane
Check this option to extrude half the given length to either side of the sketch or face, if Type is Dimension, or Through all if that is the Type.
Reversed
Reverses the direction of the pocket.
Direction
Direction/edge
You can select the direction of the extrusion:
- Sketch normal or Face normal: The sketch or face is extruded in the opposite direction of its normal. If you have selected several sketches or faces to be extruded, the normal of the first one will be used.
- Select reference...: The sketch or face is extruded in the opposite direction of a straight edge or a datum line selected from the Body.
- Custom direction: The sketch or face is extruded in the direction of the specified vector.
Show direction
If checked, the pocket direction will be shown. In case the pocket uses a Custom direction, it can be changed.
Length along sketch normal
If checked, the pocket length is measured along the sketch or face normal, otherwise along the custom direction.
Taper angle
Tapers the pocket in the extrusion direction by the given angle. A positive angle means the outer pocket border gets wider. Note that inner structures receive the opposite taper angle. This is done to facilitate the design of molds and molded parts. This option is only available if Type is Dimension or Two dimensions.
2nd taper angle
Tapers the pocket in the opposite extrusion direction by the given angle. See Taper angle. This option is only available if Type is Two dimensions.
Properties
Data
Part Design
- DatiRefine (
Bool): True or false. Cleans up residual edges left after the operation. This property is initially set according to the user's settings (found in Preferences → Part Design → General → Model settings).
- DatiType (
Enumeration): Defines how the pocket will be extruded, see Options. - DatiLength (
Length): Defines the length of the pocket, see Options. - DatiLength2 (
Length): Second pocket length in case the DatiType is TwoLengths, see Options. - DatiUse Custom Vector (
Bool): If checked, the pocket direction will not be the normal vector of the sketch but the given vector, see Options. - DatiDirection (
Vector): Vector of the pocket direction if DatiUse Custom Vector is used. - DatiReference Axis (
LinkSub) - DatiAlong Sketch Normal (
Bool): If true, the pocket length is measured along the sketch normal. Otherwise and if DatiUse Custom Vector is used, it is measured along the custom direction. - DatiUp To Face (
LinkSub): A face the pocket will extrude up to, see Options. - DatiOffset (
Length) - DatiTaper Angle (
Angle) - DatiTaper Angle2 (
Angle)
Sketch Based
- DatiProfile (
LinkSub) - DatiMidplane (
Bool) - DatiReversed (
Bool) - DatiAllow Multi Face (
Bool)
Limitations
Limitazioni
- Quando è possibile utilizzare il tipo Quota oppure Attraverso tutto perché gli altri tipi a volte danno problemi quando essi vengono utilizzati per essere replicati in schiere.
- Inoltre, la funzione tasca ha le stesse limitazioni della funzione Pad.
