Diametro

Descrizione

Lo strumento Raggio aggiunge una dimensione di diametro a una vista. La dimensione può essere applicata a qualsiasi bordo circolare del disegno. Inizialmente viene indicato il valore della distanza proiettata (vale a dire, come mostrato nel disegno), ma questo valore può essere sostituito con quello dell'effettiva distanza 3D utilizzando lo strumento Link alla dimensione.

Misurare un cerchio, indicando il raggio

Uso

1. Selezionare un cerchio o arco di cerchio nel disegno. (Notare che alcuni archi che sembrano essere circolari sono in realtà ellissi o B spline. In questi casi non si può creare una dimensione di raggio)
2. Premere il pulsante File:Dimension Radius.png Raggio
3. Alla Vista viene aggiunta una dimensione. La dimensione può essere trascinata nella posizione desiderata.

Limitazioni

Gli oggetti dimensione sono vulnerabili ai problemi di "denominazione topologica". Per maggiori informazioni vedere le informazioni nello strumento Lunghezza.

Proprietà

This object has the same properties as the TechDraw Dimension Length tool. See that tool for details.

Script

Le dimensioni raggio possono essere aggiunte alle pagine utilizzando Python.

See also: TechDraw API and FreeCAD Scripting Basics.

The Dimension Radius tool can be used in macros and from the Python console by using the following functions:

dim1 = FreeCAD.ActiveDocument.addObject('TechDraw::DrawViewDimension','Dimension')
dim1.Type = "Radius"
dim1.References2D=[(view1, 'Edge1')]
rc = page.addView(dim1)
