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.

Base Body The original body.

Base Component A component from which at least one body has been promoted.

7.5. Promote Body restrictions

Promoted bodies have the following restrictions:

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 Allowed?

Promoted Promoted Yes

Not promoted Promoted No

Promoted Not promoted Yes

Not promoted Not promoted Yes

8. Instance Feature

Use the Instance Feature command to:

Create patterns such as bolt hole circles.

Create a number of similar features such as ribs.

Edit all instanced features in one step.



You can define three Instance Feature types:

Rectangular Array

Circular Array

Pattern Face

You can add edge blends, chamfers, and threads to an Instance feature.

If you create:

An edge blend you can select Blend All Instances.

A chamfer you can select Chamfer All Instances.

A thread you can select Include Instances

When you select these options, always add the edge blend, chamfer or thread to the master feature,

and not to one of the instanced features. This way, if the array parameters are changed, the edge

blend, chamfer or thread will always remain visible in the instance set.

You cannot instance the following objects:

Shells

Chamfers

Blends

Offset sheets

Datums

Trimmed sheet bodies

Instance sets

Draft features

Surfaces

Trimmed features

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

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.

Identical

Creates an instance array in the fastest way.

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 they 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.
