Mouse
For a standard use of the mouse, the buttons are described as follows:
- M1: Left Button (picking button)
- M2: Central Button (movement button)
- M3: Right Button (menu button)
Using the mouse (that moves the pointer on the screen), the user can:
- Do movements in the 2D and 3D views (movement button M2). The middle mouse button can be used for rotations, translations and clipping according to the function (F2 to F5), Shift or Ctrl keys of the keyboard. All transformations are relative to the screen reference: coordinates X, Y, and Z are respectively horizontal, vertical, and normal to the screen surface. The cursor shape changes during the transformation, indicating the type of transformation being performed:
·
: any rotation around the model origin.
Default mode of the middle mouse button.
·
: any translation in the screen XY plane. Ctrl + M2.
·
: rotation around the origin of the model in
the screen XY plane only (about the screen Z-axis). Ctrl + Shift + M2.
·
: zoom-in or out the view along the screen
Z-axis. Shift key + M2.
Note:
· If the workstation uses a Windows 2000, NT or XP operating system, and is equipped with a mouse track ball as middle button, mouse wheel actions will correspond to a zoom-in and out.
·
: rotation of a section plane around any
axis. Alt + M2.
- Gain access to the various contextual menus of the graphic windows (menu button M3),
- Click on controls or lists of the interface (interface button M1). The standard Shift and Ctrl keys apply for multiple selections in a list (range selection and non-contiguous group selection respectively).
- Select entities in the graphic windows (picking button M1). Two modes can be distinguished:
· Picking an entity such as a node, an element, and a material by clicking with the mouse left button on this entity. A second picking on an entity already selected deselects it. The standard Shift and Ctrl keys apply for multiple selections (range selection and non-contiguous group selection respectively).
· Picking several entities by defining a window: click one point of a diagonal with the mouse left button, drag then release the mouse button on a second point.
Limitations:
· For curves, i.e. 2D graphical area, the only authorized graphical manipulations are picking, translation and zooming.
