| Working with/without the manipulator in
Silo. |
Silo is a manipulator-based program, though
you can now use it equally well with the main manipulator turned off if
you prefer. The main manipulator centers itself on your
selection, while the alternate manipulator stays in the corner of the
screen. Either can be clicked on and dragged to transform your
selection.
|
There are five different options for your
manipulator tool: universal, move, scale, rotate, and no manipulator.
These are accesible from the right-click menu or from hotkeys "Q", "W",
"E", "R", and "T".
|
Each of the manipulators has handles that
you can click and drag on to perform their respective operations in the
axis chosen. For example, click on the green arrow of the
move manipulator to move your selection in the direction it points.
|
You can also use keyboard shortcuts to
constrain your operation to a particular axis or plane. If
the move manipulator is the active manipulator and you press a keyboard
shortcut assigned to "Constrain to XZ Plane", moving your mouse will
move your selection in the plane of the manipulator's x and y
axes. Alternately, if you click and drag on the manipulator's z
axis, then press a key to constrain movement to the x axis, motion will
also be constrained to the xz plane.
|
You can adjust the manipulator's
orientation from the Orient Manipulator and Auto Orient Manipulator
sub-menus in the Selection menu. The Auto Orient menu will
determine how the manipulator is oriented at each new selection, while
the Oreint menu will perform the orientation only for the current
selection. The Enable Repositioning check allows you to set
whether the manipulator repositions
(as opposed to reorienting)
itself when a new selection is made.
|
You can toggle the display of the
manipulators in the Display menu (Display > Show Manipulator and
Display > Show Alternate Manipulator). If you want to
work without the manipulator, we suggest you turn off the display of the
main manipulator and leave the alternate manipulator on, so you can tell
which manipulator tool is active.
|
If you want to move or rotate the
manipulator without moving or rotating the selection, activate
manipulator edit mode (Selection > Manipulator Edit Mode or press the
Insert key). The manipulator will turn all white to signify
that you are in this mode. Uncheck the menu item or press Insert
again to exit the mode when you have positioned and oriented the
manipulator how you want it.
