Design Intent

The engine must meet the following design intent requirements:

The side fins should be created using a rectangular pattern.

This avoids having to create and sketch each pocket individually.

The hole pattern should be created using a user-defined pattern.

This feature can also be created as a rectangular pattern; however, a user-defined pattern will enable you to customize the hole locations.

The model should be partially created by copying and pasting features.

This is one way of quickly recreating duplicate features.

The model should include features from a catalog.

This is a typical way to retrieve data from a source that is accessible to everyone.

Introduction to Duplicating Features

CATIA allows the creation of various types of features; however, some features always occur multiple times in a model. In order to avoid having to create each one individually, duplication tools are used. Two types are discussed in this lesson:

A. Mirror Using the Mirror tool, you can create

one half of a symmetrical part and duplicate the opposite side about some reference.

B. Pattern Patterns enable you to create several

identical features from an existing one, and to simultaneously position them on a part.

Mirror

When designing parts, it is a good idea to identify any areas of symmetry before beginning to model. This enables you to plan and reduce the amount of work needed by only building half of the part, then using the Mirror tool to build the other side. You can also mirror individual features.

Use the following steps to create a mirror feature:

1. Select the Mirror icon.2. Select a datum plane or planar surface that

will be the plane of symmetry.3. Select OK.

Exploding a Pattern

After a pattern is created, individual instances may need to be modified such that they are independent from each other and the original source feature. The instances of the pattern can be separated into individual features using the Explode option.

Use the following steps to explode a pattern:

1. Select the pattern in the specification tree.2. Click the right mouse button.3. Select object > Explode

Removing Individual Instances in a Pattern

When you create a pattern, CATIA gives you the option to remove individual instances before the pattern is completed.

While the Pattern definition window is open, click on the centers of the instances that you do not want to keep. To activate an instance you removed, click on its center again.

Keep Specification

When you pattern a feature, the pattern instances appear identical to the original feature. Use the Keep specifications option to maintain the design intent of the original.

In the example below, the pad is created with an Up to Surface depth. If the Keep specificationsoption is not selected, the pattern instances retain the state of the original feature during pattern creation.

Introduction to Transformation Features (1/2)As you create a model, you may need to occasionally move features. This is accomplished using transformation features. These features enable you to move a body by translating it along an axis, rotating it round an axis, or moving it symmetrically about a plane.

There are three types of transformations features:

A. TranslateB. RotateC. Symmetry

Using Transformation Features

Transformations are useful when you have created some geometry and you decide that it needs to be moved or rotated into a specific position.

There are some cases where it is not easy to create geometry in the expected plane because it requires the use of geometry not in that plane. You can create the geometry in a different plane, then rotate or translate it to its required position.

Translation (1/2)The Translation tool allows you to move a body in a linear direction. You may define the translation vector in the following three ways:

A. Direction, distance Moves the body a distance along a linear

direction defined by a reference, such as an edge or plane.

B. Point to point Moves the body from one point to

another. The relative position of the body with respect to the end point is the same as it was with respect to the start point.

C. Coordinates Moves the body with respect to a

Cartesian coordinate system.

Differences in Transformations

Transforming a body can be done using the transformations tools or using the compass. Using the compass to move items is discussed in an upcoming lesson.

Immediately upon selecting any transformation tool a Question panel appears, as shown below.

Selecting Yes will proceed to the use of the Transformation as selected. The message in the panel reminds you that you can also transform a body by using the Compass. This is useful since you cannot use a Transformation to transform sketched geometry, but you can using the Compass.

A part gets scaled differently depending on the type of element used as the reference.If a point is used, the scaling is done using the same scaling ratio in all three directions.

In the design of the model for an injection molded plastic part, the design part will often be scaled up to account for material shrinkage upon cooling. Depending on the material, the part may shrink by different amounts in each direction.

In these situations, you cannot use a point as the reference. You must use a plane or planar face features. This will scale the part only in a direction normal to that plane. You can then do three separate scaling transformations in each of three directions which will properly define the shrink in all three directions.

Copy and Paste (1/4)Features can also be duplicated by copying and pasting them within a part. The pasted feature is identical and completely independent of the original feature.

Use the following steps to perform a copy and paste:

1. Select the feature to be copied.2. Click the right mouse button.3. Select Copy.

Copy and Paste (4/4)Features can also be copied between separate part files. The procedure is the same as copying and pasting within a single part.To perform this operation, you need to pay attention to the references that were used to construct the original feature. In order for the paste to be successful, the same type of references must also exist in the target part file; otherwise the pasted feature will fail.

Some references are considered equivalent. For example, instead of selecting a face on the PartBody in the target part to paste the pad feature, you can select a surface to paste to. What this does is change the sketch support of the pads sketch to the surface you just selected.

Introduction to Catalogs (2/2)In Part mode, features can be stored as power copies or user features.

A User Feature is a group of feature(s) that exist as one entity. When placed in a model it is represented by a single feature.

A Power copy is also a group of feature(s) that exist as one entity. However when placed in a model the original order and state of the features are preserved. This gives better flexibility in terms of modifiability after placement of the power copy.

These two are stored in the part they were created in, but also can be saved into a catalog. Instantiating the items can be done from the stored catalog or the part the power copy and user feature were created in.

Power Copy (1/3)A power copy can consist of a feature or group of features. It differs from a typical copy because it allows the user to address references of the copied features when pasting it into its new location. The references are controlled through inputs and parameters.

Use the following steps to create a power copy within a part:

1. Click Insert > Knowledge Templates > power copy.

2. The Powercopy Definition window opens at the Definition tab where you can customize the name of the power copy and select the features to include.
