Descrizione

Dà il valore Delta tra 2 punti è la lunghezza tra i due punti.

Se viene premuto il tasto SHIFT, il valore Delta inizia dalla coordinata 0,0,0 fino al punto cliccato (la coordinata 0,0,0 viene visualizzata in rosso).

Un'opzione è possibile affinché la macro rimanga residente (continua) quindi premere Q per uscire dalla macro e un'opzione per imporre il numero di decimali.

Utilizzo

1. Lanciare la macro
2. Selezionare il primo punto nella vista 3D
3. Selezionare il cecondo punto nella vista 3D è vera li informazione nella vista rapporto

Se viene premuto il tasto SHIFT, il valore Delta inizia dalla coordinata 0,0,0 fino al punto cliccato (la coordinata 0,0,0 viene visualizzata in rosso).

Se è configurato "Permanente" (continuo), fare clic sul tasto Q per uscire dalla macro

Configurazione

Per modificare il valore: vai a : FreeCAD → Menu → Tools → Edit parameters... → BaseApp/Preferences/Macros/FCMmacros/Delta_XYZ.

_____switchDecimalsPref_____

• true 1: il valore arrotondato assume il valore delle preferenze globali
• false 0: il valore arrotondato prende la tua scelta

_____setArrondi_____

• imposta il valore arrotondato della tua scelta
• se la tua scelta = 0: il valore rotondo è 3 per impostazione predefinita

_____switchResident_____

• true 1: la macro rimane residente (digita Q per uscire)
• false 0: la macro viene utilizzata durante l'esecuzione e si chiude dopo l'uso
