Rigid Transform
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.
Enter the properties of the rigid transform using the following sections:
Input
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.
Coordinate System for Objects
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).
Coordinate System to Match
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.
Displacement
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.
Rotation
From the Specify list, choose Axis of rotation (the default) or Euler angles (Z-X-Z) as the way to specify the rotation.
Axis of 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).
Euler Angles (Z-X-Z)
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).
Selections of Resulting Entities
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.
Cumulative Selection
If you want to make the resulting entities contribute to a cumulative selection, select a cumulative selection from the Contribute to list (the default, None, gives no contribution), or click the New button to create a new cumulative selection (see Cumulative Selections).
