- Part
instances
-
You can suppress, resume, and delete part instances. You can partition a
part instance, but you cannot edit its shape or its features. To modify a part
instance, you must edit the original part in the
Part module;
Abaqus/CAE
automatically regenerates instances of a modified part when you return to the
Assembly module.
You can make a part instance invisible while still retaining it in the
assembly by selecting
from the main menu bar. For more information, see
Controlling instance visibility.
This technique is not the same as suppressing a part instance; a suppressed
part instance is removed from the assembly until you resume it. You can also
use display groups to make part instances invisible; for more information, see
Using display groups to display subsets of your model.
You can link part instances, and you can exclude part instances from an
analysis; for more information, see
Linking part instances between models
and
Excluding part instances from an analysis.
- Model
instances
-
You can suppress, resume, and delete model instances. To modify a model
instance, you must edit the original model's assembly.
You can make a model instance invisible while still retaining it in the
assembly by selecting
from the main menu bar. You can also use display groups to make model instances
invisible.
- Position
constraints
-
You can edit, suppress, resume, and delete position constraints. You can
modify the following parameters of a position constraint:
-
The direction of the arrow normal to the selected face or along the
selected edge of the movable part instance.
-
The clearance between the selected face or edge of the movable part
instance and the selected face or edge of the fixed part instance. The
clearance parameter applies only to face-to-face, edge-to-edge, and contact
constraints.
Translations and rotations are not stored as features and cannot be edited,
suppressed, resumed, or deleted.
You can use the
Feature Manipulation toolset
to modify features of the assembly. When you are prompted to select a feature
to modify, you can select a visible feature such as a part instance, a datum,
or a partition from the viewport. However, to select a position constraint, you
must select it from the
Model Tree.
The following feature manipulation tools are available from the
Feature Manipulation toolset:
- Edit
-
When you edit a feature,
Abaqus/CAE
displays the Edit Feature dialog box and you can modify
the feature's parameters or the sketch that defined the feature. You cannot
edit part instances; you must return to the
Part module
to modify the original part.
- Regenerate
-
When you modify features in a complex assembly, it may be convenient to
postpone regeneration until you make all your changes, since regeneration can
be time consuming. Select
when you are ready to regenerate the assembly.
- Rename
-
Rename a feature.
- Suppress
-
Suppressing a feature temporarily removes it from the definition of the
assembly. A suppressed feature is invisible, cannot be meshed, and is not
included in the analysis of the model. Suppressing a parent feature will
suppress all of its child features.
- Resume
-
Resuming a feature restores a suppressed feature to the assembly. You can
choose to resume all features, the set of features most recently suppressed, or
just a selected feature.
- Delete
-
Deleting a feature removes it from the assembly; you cannot restore a
deleted feature.
- Query
-
When you query a feature,
Abaqus/CAE
displays information in the message area and writes the same information to the
replay file (abaqus.rpy) in the
form of comments.
- Options
-
The Feature Options dialog box allows you to control
whether
Abaqus/CAE
performs self-intersection checks and enables you to prioritize the
regeneration of constraint features over other assembly features.

Feature Manipulation toolset,
