Modify General Part

General Part

Enter the name of the general part you want to modify.

Tips on Entering Object Names in Text Boxes.

Location

Enabled if the general part's location was defined to be User Entered when created. Enter the x, y, and z values for the general part's location, separated by commas (for example, -100, 200, 50).

If the location was defined at creation time using a location expression, the Location text box is disabled and the location cannot be modified in Standard Interface.

Location defines the initial Cartesian coordinates of the origin of the part’s Body Coordinate System (BCS) with respect to the Global Coordinate System (GCS).

Orient using

Select if you want to orient the general part using:

Euler Angles

Enter the three Euler angle values that define the general part's orientation.

X Vector

Enter the x, y, and z values that define the direction of the x-vector along which the general part will be oriented.

Z Vector

Enter the x, y, and z values that define the direction of the z-vector along which the general part will be oriented.

If you selected a rigid body, your template-based product enables the following options:

Mass

Enter the mass of the general part.

Ixx/Iyy/Izz

Enter the values that define the moments of inertia components of the general part. The inertia reference frame is parallel to BCS at the center of mass (CM) location. Learn About Entering Mass Moments of Inertia.

Off-Diagonal Terms

Select to display and undisplay the Ixy/Izx/Iyz text boxes.

Sprung Mass %

Enter percentage contribution of part total mass into sprung mass. Select a location of sprung mass contribution from the list for the subsystem with role other than front or rear. (Used only for SVC event)

Ixy/Izx/Iyz (optional)

Enter the values that define the products of inertia components of the general part. The inertia reference frame is parallel to BCS at the center of mass (CM) location.

CM Location Relative to Part (optional)

Enter the x, y, and z values of the location offset. You can offset the center of mass and inertia markers of the general part a specified distance from the general part's Body Coordinate System location. Learn about Markers.

Density

Select one of the following

Material Type

Select a material type from the list of materials currently defined. When you select a material, your template-based product uses the density defined for that material to calculate the general part's mass and inertia properties.

Density Value

Enter a density that your template-based product will use to calculate the general part's mass and inertia properties.

Select to calculate and display the mass and inertia into the respective fields.

Select to open the Geometry Manager. Use this tool to modify geometry defined at the subsystem level.

If you selected a flexible body, your template-based product displays the following options:

MNF File/
MD DB File/
BDF File

Select a file that represents the flexible body.

Tips on Entering File Names in Text Boxes.

If you have several different modal neutral files that all represent the same part but have different modal flexibility characteristics, you can switch between them by selecting the desired file. Note that this does not give you the same level of control as performing a Flex to Flex swap.

Select to display the Flexible Body Mode Manager, where you can view/animate mode shapes and perform other operations, such as defining the deformation scale factor and inertia modeling, or enabling/disabling modes.

Select to Modify Flexible Body Connections.

Symmetric

Enabled when you modify component pairs (or brothers):

When you modify a single component, this option is disabled because a single component is by nature asymmetric.

Select to display a dialog box where you can add multi-line comments to any entity, to describe its purpose and function. Your template-based product displays different comments dialog boxes, depending on the entity type for which you want to record comments:

Learn about Recording Comments.

Rigid to Flex/
Flex to Flex

Select to replace a rigid body with a flexible body or a flexible body with another flexible body. Your template-based product displays the appropriate dialog box:
