Mouse Model/bg

"Модела за работа с Мишката" в се състои от командите които се използват за да се навгира в 3D пространството и да се работи с обектите в него. FreeCAD подържа няколко стила на навигация с мишка. Стилът по-поразбиране се нарича "CAD Навигация," и е доста прост и практичен. FreeCAD също предлага алтернативни стилове (модели) за навигация, които може да изберете спрямо вашите предпочитания.

Навигация
Стилът на навигацията и работа с обектите е един и същ във всички работни плотове. Долуописаните жестове на мишката могат да се използват за да ес контролира позицията на обекта и изгледа към обекта (в зависимост от кой стил на навигация е избран).

There are two ways to change the navigation style:


 * In the Preferences Editor, Display section, 3D View tab;
 * By right-clicking in empty space in the 3D view area, then selecting Navigation style in the contextual menu.

CAD Navigation (default)
This is the default navigation style and allows the user a simple control of the view, and does not require the use of keyboard keys except to make multi-selections.

Inventor Navigation
In Inventor Navigation, modeled after Open Inventor (not to be confused with Autodesk Inventor), there is no mouse-only selection. In order to select objects, you must hold down the key.

Blender Navigation
In Blender Navigation, modeled after Blender, there is no mouse-only panning. In order to pan the view, you must hold down the key.

Touchpad Navigation
In Touchpad Navigation, neither panning, nor zooming, nor rotating the view, are mouse-only (or touchpad-only) operations.

Gesture Navigation (v0.16)
This navigation style was tailored for usability with touchscreen and pen, but is very usable with mouse too.

Maya-Gesture Navigation
In Maya-Gesture Navigation, all view movements are archived pressing and a mouse button, so that it will be needed to have a 3 button mouse in order to correctly use this navigation mode. Alternately it's possible to use gestures as this mode was been developed over the normal Gesture Navigation mode.

Simple selection
Objects can be selected by a click with the left mouse button either by clicking on the object in the 3D-view or by selecting it in the tree view.

Preselection
There is also a Preselection mechanism that highlights objects and displays information before selection by just hovering the mouse over the objects. If you don't like this behaviour or you have a slow machine, you can switch preselection off in the preferences.

Manipulating Objects
FreeCAD offers manipulators that are handles that can be used to modify an object's appearance, shape, or other parameters.

Hardware support
FreeCAD also supports some 3D input devices.

Mac OS X Issues
Recently we got reports on the forum from Mac users that those mouse button and key combination do not work as expected. Unfortunately, none of the developers owns a Mac, neither do the other regular contributors. We need your help to determine which mouse buttons and key combination work so we can update this wiki.
