Descrizione

Diminuisce la molteplicità del nodo di curva B-spline (vedere: B-spline).

File:Sketcher SampleBSplineDecreaseKnotMultiplicity example.png

Curva B-spline che mostra una molteplicità di nodi decrescente.

Utilizzo

1. Selezionare un nodo di una B-spline
2. Richiamare lo strumento usando uno di questi metodi:
   • Premere il pulsante Diminuisci la molteplicità nella barra degli strumenti.
   • Usare la voce Sketch → Strumenti B-spline → Diminuisci la molteplicità dal menu principale.
