    1. Trim Body

    Use Trim Body to trim one or more target bodies using a face or plane. You can specify the portion of

    the body to retain and the portion to discard. The target bodies take the shape of the trimming geometry.

    You must select at least one target body.

    You can select a single face, multiple faces from the same body, or a datum plane to trim the

    target bodies.

    You can define a new plane to trim the target bodies.

    Lets you select one or more faces from a body or an existing datum plane to use to trim

    the target bodies. Multiple tool faces must all be from the same body.

    When the target is one or more solid bodies, the face trimming tool must form a

    complete intersection with all selected bodies.

    When the target is one or more sheet bodies, the face trimming tool extends

    automatically along a linear tangent, and fully trims all selected sheet bodies it

    2. Split Body

    Use the Split Body command to split a solid body or sheet body into multiple bodies using a set of faces

    or a datum plane. You can also create a sketch internal to the command and either extrude or revolve it to

    create the splitting tool. This command creates an associative Split Body feature that appears in the

    history of the model. You can update, edit, or delete the feature.

    This command is useful in a modeling approach where multiple parts are modeled as a single part and

    then split as required. For example, a housing that consists of a base and a cover can be modeled as one

    part and split later.

    Trim Bodies drive24ward (meslab.org/mes)

    Note When you split a solid body using a face, the face must be large enough to cut through the

    body completely.

    For help with creating a split body in a CAE workflow, see Split Body overview in the

    Advanced Simulation help.

    In earlier versions of NX, the Split Body command removed all parameters from a solid or

    sheet body that was split. As of NX 6 this is no longer true. Bodies are no longer

    automatically de-parameterized when they are split.

    Trim Bodies drive24ward (meslab.org/mes)

    If Keep Imprinted Edges is selected, imprinted edges are saved and revealed

    when you hide the top solid body.

    If Keep Imprinted Edges is not selected, imprinted edges are discarded and

    not present when you hide the top solid body.

    Note An existing edge can be considered an imprinted edge if it forms part of the

    intersection between faces from the target and the tool.

    When working in Advanced Simulation with an idealized part active, the Keep

    Imprinted Edges option becomes Auto Create Mesh Mating Conditions. For

    details about this option, see Split Body overview in the Advanced Simulation help.

    2.4. Split Body failure conditions

    If you are splitting a solid body, the split operation may fail if:

    The face being used to split the body is tangent to the face of the body.

    The face of the body is coincident with any joint of adjacent faces of the splitting sheet body.

    Shaded face of the splitting sheet and the face of the body to be split are tangent

    Joint of the splitting sheet and the face of the body to be split are coincident

    Splitting sheet (multifaced)

    To resolve this problem, try the following.

    Extract sheets from the solid body.

    Trim the sheets with curves and/or planes.

    Create any necessary caps and sew the sheet bodies into a solid body.

    3. Trimmed Sheet

    Use the Trimmed Sheet command to trim sheet bodies to intersecting faces and datums, and projected

    curves and edges.

    The following example shows a sewn sheet body trimmed by two intersecting surfaces and one set of

    projected curves.

    Extension

    Method

    Specifies the type of continuity for an extension operation.

    Natural Tangent

    The extension is linear in the direction of the tangent to the face at the selected

    edge. This type of extension is tangent (C1) continuous.

    Natural Curvature

    The extension of the face is curvature continuous (C2). This is done by using an

    algorithm that ensures C2-continuity at the start of the extension, and then tends

    toward linear after a small distance.

  • [NX8-HELP] TRIM BODIES 26

    Trim Bodies drive24ward (meslab.org/mes)

    Mirrored

    The extension of the face reflects or "mirrors" the shape of the face being

    extended, where possible.

    The angular deviation of an extended surface between Natural Tangent and Natural

    Curvature is usually about 3 degrees.

    Selected edge to extend

    Natural Tangent

    Natural Curvature

    Mirrored

    Note Note: The shape of the mathematical surface that underlies the face being

    extended can have a noticeable effect on the shape of the extended face. If two

    faces that appear to be identical have different underlying mathematical surfaces

    (such as an analytic and a b-surface), performing the same extension on each face

    can lead to different results.

    The geometry immediately surrounding the edge to extend can also have an effect on the

    shape of the extension.

    When you create an extension using Natural Tangent, a G2 discontinuity may be

    created at the boundary of the underlying surface.

    Extend as

    New Face

    (Keep Old

    Face)

    Keeps the original edges on the target or tool face. The input edges are unaffected by the

    trim or extend operation, and remain in their original state. New edges are created based

    on the output of the operation and are added as new objects.

    This option works only if edges are selected for input.

    Tolerance The tolerance value used to create the feature. The default is taken from the tolerance

    setting in Modeling preferences.

    Undo Result

    Show Result displays what the result looks like using the actual computation to create it.

    The currently assigned part shading colors are used for the display. When you click OK

    or Apply to create the feature, the software reuses the Show Result computation,

    making the creation process faster.

    Undo Result exits the result display and returns you to the dialog box.

    5. Untrim

    The Untrim command enables you to remove imposed boundaries and extends planar, cylindrical,

    and conical faces in the linear direction of the selected face.

    Instead of extracting multiple faces and then extending them, use the Untrim command to perform

    additional modeling tasks on a specific region of an existing model.

    You can use faces of a solid body, or a sheet body as input. The selected faces are copied and extended

    along their axis to create an associative untrim feature.

    Note An untrimmed face is inherently unsewn.

    For more information about the Unsew feature, see Unsew.

    6. Divide Face Use the Divide Face command to divide one or more faces of an existing body (or bodies) using multiple

    dividing objects like curves, edges, faces, datum planes, and/or solid bodies. The faces are associative.

    You can use Divide Face to create parting edges on models of parts, patterns, molds, or dies.

    Projection Direction

    Projection Direction

    Lets you specify a direction to project the selected objects onto the surface being

    divided.

    Normal to Face Makes the projection direction of the dividing object normal to the selected face, or faces, to be divided.

    Normal to Curve Plane Makes the projection direction normal to the plane of the curves when you select coplanar curves or edges as the

    dividing objects.

    If the selected set of curves or edges do not lie in the same plane, the

    projection direction is automatically set to Normal to Face.

    Along Vector Specifies a projection vector for the divide face operation.

    Specify Vector becomes available and you can click Vector Constructor

    or use the option list to specify the direction.

    Reverse Direction

    Reverses the displayed vector direction.

    Controls the projection of any curves that lie within faces and are selected as

    dividing objects.

    When selected, the portions of dividing objects that lie within a face are not

    projected to any other faces that are selected for division. When not selected,

    dividing curves are projected to all faces to be divided.

    7. Delete Edge

    Use the Delete Edge command to delete an edge or chain of edges from a sheet body. You can use it to

    remove a hole, or to untrim an exterior boundary.

    If you want to remove specific edges from a sheet body, use the Delete Edge command. If you use the

    Untrim command the sheet body is copied. The copy is returned to its natural boundaries and you may

    need to retrim some edges.
