Beschreibung

Über diese GUI kann die Ansicht präziser gedreht werden als bei Verwendung der Maus. Die Rotation richtet sich nach den Achsen, die in Bezug auf den Benutzer festgelegt sind, und nicht auf die Objekte. Das Ziel besteht jedoch darin, dass sich die Objekte um ihre ungefähre gemeinsame Mitte herum drehen, anstatt um die Ansichtsmitte Die GUI befindet sich standardmäßig rechts oben auf dem Bildschirm. Dieses Verhalten kann durch Bearbeiten geändert werden

Rotate view

Mit drei Symbolen werden die Drehrichtungen symbolisiert. Eine ZIP-Datei mit diesen Symbolen finden Sie here, die Bilder sollten sich in dem Ordner befinden, der Ihre Makros enthält. Bitte zögern Sie nicht, bessere beizutragen!

Code

Die neueste Version des Makros finden Sie unter ViewRotation.FCMacro. Der einfachste Weg, dieses Makro zu installieren, ist das Addon Manager.

# -*- coding: utf-8 -*-
#
# FreeCAD macro ViewRotation.
# This GUI allows the view to be rotated with more precision than when using
# the mouse. Rotation is according to axes fixed with respect to the user and
# not the objects, though the aim is that the objects rotate about their
# approximate shared centre rather than the view centre.
# The GUI defaults to the top right of the screen, this behaviour can be
# changed by editing.

am Ende der Funktion 'initUI'. Die ersten beiden Argumente (rechts-300, 0) (Zeile 91) geben die Position für die obere linke Ecke des Fensters an. Ich habe die Erfahrung gemacht, dass das Verhalten auf Ubuntu wie beabsichtigt war, aber Vista positionierte das Fenster zu hoch und die 0 dazu in ~ 30 geändert werden.
