Beschreibung

Dieses Makro erstellt einen Kreis, der an 3 ausgewählten Punkten orthogonal oder in 3D im Optionsraum umschrieben wird. Punkte können Objekte wie Würfel, Zylinder usw. sein. Die ausgewählten Koordinaten bilden dann den Mittelpunkt dieser Formulare.

Macro Draft Circle 3 Points01.png

Erzeugt einen Kreis aus 3 ausgewählten Punkten oder Formen


Verwenden Sie

Wählen Sie 3 Punkte oder Formulare in der 3D-Ansicht aus und führen Sie das Makro aus.
Wenn die Form eine Linie ist, ist die Koordinate der Mittelpunkt der Linie.

Circle_on_3_points

Optionen

Modus:

Defaut:

Modus erstellt standardmäßig einen Kreis auf den drei Punkten oder Formen im 3D-Raum.
Die Reihenfolge der Auswahl der Angstformen beeinflusst den Winkel AXIS und kehrt die Neigung des Kreises um. In diesem Fall können Sie die Reihenfolge der Auswahl der Formen umkehren oder ändern.
Koordinaten X, Y, Z Wert 0 oder Ausrichtung erlaubt keine Berechnung, kann eine Division durch Null-Fehler zurückgeben und mit übersetzt werden. Die drei Punkte sind ausgerichtet.

Vue Face:

Erzeugt den Kreis in den Vorderansichten des ausgewählten Formulars 1, 2 oder 3

'Vue Dessus:'

Erzeugt den Kreis oben in der Formularansicht 1, 2 oder 3

Vue Droite:

Erzeugt den Kreis in der Ansicht von rechts in der gewählten Form 1, 2 oder 3

Ausrichtung sur:

Forme 1, 2, 3

Formulare in der Reihenfolge ihrer Auswahl.

Zweigstelle:

Wenn dieses Kontrollkästchen aktiviert ist, wird ein Punkt in der Mitte des erstellten Kreises erstellt

Farben zuordnen

Wenn dieses Kontrollkästchen aktiviert ist, nimmt der Kreis die Farbe der entsprechenden Ansicht an.
View-Top (X, Y) = Blau (Axt Z)
Ansichtsfront (Z, X) = Grün (Axt Y)
Ansicht-Links (Z, Y) = Rot (Axt X)
