Lunghezza, Estensione verticale

Descrizione

Lo strumento Estensione orizzontale aggiunge una quota lineare a una vista. La dimensione si estende dal punto più a sinistra degli oggetti selezionati al punto più a destra. Viene posizionato un vertice cosmetico nei punti estremi.

Estensione orizzontale della faccia BSpline

Usage

1. Selezionare una vista o una serie di bordi in una vista.
2. Premere il pulsante Estensione orizzontale.
3. Viene aggiunta dimensione alla vista. La dimensione può essere trascinata nella posizione desiderata.

Change properties

To change the properties of a dimension object either double-click it in the drawing or in the Tree view. This will open the Dimension dialog.

Limitazioni

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

Notes

See TechDraw LengthDimension.

Proprietà

Questo oggetto ha le stesse proprietà dello strumento Lunghezza. Eccezioni rilevate.

Dati

Base

• DatiMeasureType: true - basata sulla geometria 3D o "Projected" - basata sul disegno. Normalmente non manipolato direttamente dall'utente finale. Non ancora implementata per Estensione orizzontale.

Script

Lo strumento Estensione orizzontale può essere utilizzato nelle macro e dalla console di Python tramite la seguente funzione:

selection = ['Edge1', 'Edge2']                      # or [] for all

TechDraw.makeExtentDim(view1, selection, 0)         # view1 is a DrawViewPart; 0 for horizontal
App.ActiveDocument.DimExtent.Y = -60                # offset dimension line from dimensioned edges in Y direction
App.ActiveDocument.DimExtent.X = 10                 # offset dimension text along dimension line in X direction
App.ActiveDocument.DimExtent.FormatSpec = '%.0f'    # Dimension format

TechDraw.makeExtentDim(view1, selection, 1)         # view1 is a DrawViewPart; 1 for vertical
App.ActiveDocument.DimExtent001.X = -130            # offset dimension line from dimensioned edges in X direction
App.ActiveDocument.DimExtent001.Y = 10              # offset dimension text along dimension line in Y direction
App.ActiveDocument.DimExtent001.FormatSpec = '%.0f'

# Note the dimension names are 'DimExtent', 'DimExtent001' etc in the order created.
