Definition Mode
In the
Rotate Definition dialog box, you can define a rotation using following options available in the
Definition Mode box.
- Axis-Angle (default mode): The rotation axis is defined
by a linear element and the angle is defined by a value that can be
modified in the dialog box or in the 3D geometry by using the
manipulators.
- Axis-Two Elements: The rotation axis is defined by a linear element and the angle is defined by two geometric elements (point, line or plane).
- Axis/point/point: The angle between the vectors is defined by the
selected points and their orthogonal projection onto the rotation
axis.
- Axis/point/line: The angle between the vector is defined by the selected point and its orthogonal projection onto the rotation axis and the selected line.
- Axis/line/line: The angle between the direction vectors of the projection is defined by the two selected lines in the plane normal to the rotation axis. In case both lines are parallel to the rotation axis, the angle is defined by the intersection points of the plane normal to the rotation axis and these lines.
- Axis/line/plane: The angle is defined between the selected line and the normal to the plane.
- Axis/plane/plane: The angle is defined between the lines normal to the two selected planes.
- Three Points: See the scenario in
Creating Rotations.
