You can define a Pattern Increment by using expressions to specify pattern parameters. You can export pattern parameter values to a spreadsheet and make positional edits that are propagated back to your your pattern definition. You can explicitly select individual instance points for clocking, suppression and variance of pattern features.

You can control the orientation of a pattern.

7. Promote Body Use the Promote Body command to promote a body from a loaded assembly component to the level of the assembly. You do not need write access to the part containing the original, or the base body, in order to promote it. This can be especially important when working in a concurrent engineering environment. After you promote a body: 





You can perform operations on it, such as adding features, performing Boolean operations between it and other bodies, and so on. The effects of these operations are only visible at the level of the assembly work part in which the promotion is created, and in any other assembly that references that part. You cannot access the features that make up the base body at the assembly level. For example, you cannot suppress a feature of the base body, or change its parameters and have those changes occur only at assembly level. You must make such changes to the base body. They will be visible in the promoted body, since it is associative to the base body. Any subsequent changes to the base body are reflected in the promoted body as the promoted body is associative to the base body. However, changes made to a promoted body do not affect the base body.

Caution You must be careful when working "in context" (that is, with the work part different than the displayed part) with promoted bodies. If the assembly is the displayed part and the component is the work part, the promoted body is still displayed and this blocks the display of the base body. You should change the displayed part to the component to work on the base body. Warning You should not promote a body that depends on another body in the same part. A dependent body is created by features that generate a new body, such as a mirror body feature, an extract face feature or a midsurface feature. If you promote a dependent body and then suppress or delete the parent body or feature, you may get internal errors. Where do I find it?

7.2. Substitute a promoted part You can use the Assembly Navigator to substitute the base component of a promoted part. 1. In an assembly part, open the Assembly Navigator. 2. In the Assembly Navigator, highlight the component you want to substitute, right-click and choose Close→Part. 3. Highlight the same part, which is now closed, right-click and choose Open→Component As. 4. In the File dialog box, select the new part to substitute in. If the new part is a version of the original part, and the base body of the promotion exists in the new part, the promotion is updated to the new base body. If the new part and the original parts are not versions of each other, and if you select Allow Substitution in the Load Options dialog box, the promotion feature is presented in the Update Failure dialog box, and you can then make the required changes.

Edit a Promote Body feature

Note Editing the Promote Body feature could result in a loss of data. Unloaded parts may be affected. Exploded views will be affected. The base body will become visible. There is no operation to reparent promotions after saving. 1. Choose Edit→Feature →Edit Parameters. The Edit Parameters dialog box opens. 2. Choose the Promote Body feature from the list and click OK . The edit version of the Promote Body dialog box opens. 3. (Optional) To break the link between the Promote Body feature and its parent assembly, clear the Associative option. Warning This action breaks the link between the promoted body and the assembly parent. 4. (Optional) To change the Promote Body feature to a WAVE Linked Body, select the Convert to Linked Body option. Note This action turns the Promote Body feature into a WAVE Linked Body. If you later edit it, the edit version of the WAVE Geometry Linker opens. See the Assemblies help for details. 5. Click OK or Apply to make the changes effective.

All Modeling operations that cause the model to lose its parameterization or feature history, are not available for promoted bodies. You cannot reorder a promoted body into the component's feature list, or vice versa. You can manipulate a promoted body only when the part that it was defined in is the work part. You cannot split a promoted body into multiple bodies. If you move a body to another part of the assembly tree after it is promoted, the promotion is deleted. When you translate parts, promoted bodies are not translated. When performing operations that require a target body and a tool body, only certain combinations of target and tool bodies are supported, as shown in the following table: Target Body Tool Body

Creates a rectangular, circular, or mirror patterns of a face or set of faces.

Pattern Face

The methods are displayed in the Edit Parameters dialog box after you select the features to instance for a rectangular or a circular array. Method General

Creates an instance array from existing features and validates all geometry. A General array is allowed to cross an edge of the face and can cross over from one face to another.

Simple

Creates an instance array similar to a General instance array. The instance array creation is faster because excessive data validation and optimizing operations are not used. Creates an instance array in the fastest way. 

Identical

 

There is minimum validation. All the faces and edges of the master feature are copied and translated. Each instance is an exact copy of the original.

Use this method when you have a great many instances, and you are sure th ey are all exactly the same. Note The resulting geometry created with the Simple and Identical method should always lie on the same face as the original feature. Validate the new geometry to determine that an Identical instance array has been created correctly. Choose Analysis → Examine Geometry and in the Checks to Perform group, select Set All to validate the geometry. If the Identical array fails, use Undo and try General array.
