Use a Rigid Transform node to perform a rigid transform (translation and rotation) of 3D geometry objects. You can use this feature to position and orient geometry objects by matching a coordinate system (work plane) with another coordinate system (work plane) and then optionally performing a rotation and translation in the work plane’s coordinate system.
To add a rigid transformation, in the Geometry toolbar, from the
Transforms (
) menu, select
Rigid Transform (
). You can also right-click the
Geometry or a
Work Plane feature to add this from the
Transforms submenu.
Select the geometry objects for which you want to perform a rigid transformation in the Graphics window. The objects appear in the
Input objects list. If the geometry sequence includes user-defined selections above the
Rigid Transformation node, choose
Manual to select objects, or choose one of the selection nodes from the list next to
Input objects.
Click the Active button to toggle between turning ON and OFF the
Input objects selections.
Select the Keep input objects check box to use the selected geometry objects for further geometry operations.
Choose the coordinate system for the geometry objects from the Work plane for objects list. You can choose among all work planes in the geometry. You can also choose
xy-plane, which corresponds to the global coordinate system (this is the default).
To choose the coordinate system to match, select a work plane from the Work plane list. The default is
xy-plane, which corresponds to the global coordinate system. The work plane to match is visualized in the graphics.
Enter values or expressions for the xw,
yw, and
zw coordinates (SI unit: m) to add a displacement vector relative to the coordinate system to match.
From the Specify list, choose
Axis of rotation (the default) or
Euler angles (Z-X-Z) as the way to specify the rotation.
Select an Axis type:
xw-axis,
yw-axis,
zw-axis (the default),
Cartesian, or
Spherical. For any choice, enter an
Angle (SI unit: degrees; default 0) to rotate the orientation of the output relative to the coordinate system to match.
If Cartesian is selected, enter Cartesian coordinates values for
xw,
yw, and
zw (default values 0, 0, and 1, respectively, corresponding to the global
zw-axis) to specify the axis vector. If
Spherical is selected, specify the axis vector using spherical angles
theta and
phi in degrees (default: 0).
Enter values for the intrinsic Z-X-Z Euler angles α,
β, and
γ in the corresponding text fields (in degrees; the default values are 0).
Select the Resulting objects selection check box to create predefined selections (for all levels — objects, domains, boundaries, edges, and points — that are applicable) in subsequent nodes in the geometry sequence. To also make all or one of the types of resulting entities (domains, boundaries, edges, and points) that the resulting objects consist of available as selections in all applicable selection lists (in physics and materials settings, for example), choose an option from the
Show in physics (
Show in instances if in a geometry part,
Show in 3D if in a work plane’s plane geometry) list:
All levels,
Domain selection,
Boundary selection,
Edge selection, or
Point selection. The default is
Domain selection, which is suitable for use with materials and physics defined in domains. For use with a boundary condition, for example, choose
Boundary selection. These selections do not appear as separate selection nodes in the model tree. Select
Off to not make any selection available outside of the geometry sequence. From the
Color list, choose a color for highlighting the resulting objects selection. See
Selection Colors.
