Macro Rotate View Macro FCCamera |
Toto grafické rozhraní umožňuje pohledu aby byl otáčen s mnohem větší přesností než při použití myši. Otáčení je fixováno v souladu s osami s ohledem na uživatele a ne na objekt, ačkoliv cílem je otáčet objektem okolo jeho přibližného středu než kolem středu pohledu.
The GUI defaults to the top right of the screen, this behaviour can be changed by editing.

Tři ikony jsou označovány symbolem směru otáčení. Soubor zip obsahující tyto ikony lze nalézt zde here, obrázky by měly být umístěny ve složce obsahující makra. Neváhejte přispět lepšími!
Nejnovější verze makra se nachází na adrese ViewRotation.FCMacro, ale nejjednodušší způsob, jak toto makro nainstalovat, je přes Addon Manager.

# -*- coding: utf-8 -*- # # FreeCAD macro ViewRotation. # This GUI allows the view to be rotated with more precision than when using # the mouse.

na konci funkce 'initUI'. První dva argumenty (right-300, 0)(line 91) určují pozici levého horního rohu okna - podle mé zkušenosti je toto chování zamýšleno pro Ubuntu, ale pozicování oken ve Vistách je příliš vysoké a hodnota 0 by měla být změněna na ~30.
Tři ikony symbolizují směr rotace. Zip soubory s ikonami najdete zde, obrázky by měly být umístěny ve složce, kde je makro. Prosím, nebojte se přispět k vylepšení makra!
