Getting Started

Before getting into the detailed instructions for using Detailed Molded Part Version 5, the following tutorial aims at giving you a feel as to what you can do with the product. It provides a step-by-step exercise based on a realistic design scenario showing you how to use key functionalities for creating a complex part.

The main tasks covered in this section are:

Entering the Cast and Forged Part Optimizer WorkbenchUsing the Sew Surface Capability

Using the Advanced Draft CapabilityFilleting While Keeping an Edge

All together, the tasks should take about ten minutes to complete. The final part will look like this:

Entering the Cast and Forged Part Optimizer Workbench

This first task shows you how to enter the Cast and Forged Part Optimizer workbench.

The only pre-requisite for this task is to have a current CATIA V5 session running.

1. Select File -> New and then select Part from the dialog box, or click the Cast and Forged Part Optimizer icon

from the Welcome to CATIA V5 dialog box.

The Cast and Forged Part Optimizer workbench is displayed, ready to use. The commands for creating features are

available to the right of the window.

2. To perform this tutorial, open the GettingStarted.CATPart document. For information on where sample documents are installed by default, see Accessing Sample Documents in the Infrastructure User's Guide.

Using the Sew Surface Capability

In this first task, you will use the Sew Surface capability to combine a surface with a body. The surface you will obtain will help you perform the draft operation as you will see it in the next task.

1. Click the Sew Surface icon .

The Sew Surface Definition dialog box is displayed.

2. Apply the Hide/Show contextual command onto Yellow Surface if it is not visible.

3. Select Blend.1 as the the surface you wish to sew onto the body.

Arrows appear in the geometry, indicating the side where material will be added or kept. Clicking

an arrow reverses the given direction.

4. Use the Hide/Show contextual command to hide Blend.1. This operation lets you see the faces

to be removed.

5. Click the Faces to remove field, then select the vertical face as shown:

The selected face turns purple.

6. In the Faces to remove field, right-click to select the Tangency propagation contextual

command. All faces tangent to the selected face are now part of the selection, as indicated in the

field and on the part. All of them will be removed.

7. Click OK to confirm.

Blend.1 is sewn onto the faces. The Sew Surface feature is created.

7. Use the Hide/Show contextual command to show Blend.1 again.

You can see Blend.1 and the sewn surface.

The application displays Sew Surface.1 in the specification tree.

Using the Advanced Draft Capability

This task shows you how to perform a draft operation on two opposite sides of the part using one pulling direction. What makes the Advanced Draft capability very productive is that it also makes it possible to adjust the resulting faces on the chosen parting element, as illustrated in this scenario.

1. Click the Advanced Draft icon .

In case the icon is not displayed in the workbench, select View -> Toolbars > Advanced Draft

to access it.

The Draft Definition (Advanced) dialog box is displayed as well as an arrow indicating the

default pulling direction (xy plane) in the geometry area.

2. Specify that you wish to draft two faces from their reflect lines by clicking both icons as shown:

The Faces to draft options are no longer available. Now, three draft modes are proposed.

Draft Modes

The three draft modes available are:

● Driving/driven: the angle value you specify for one face affects the angle value of the second face.

● Independent: you specify two angle values that apply to both faces respectively.

● Fitted: you specify a minimum angle value for one side and the application ensures that both sides are adjusted onto the parting element.

3. Set Fitted.

1st Side

4. To define the first draft angle value, enter 3deg as the minimum draft angle value.

Neutral Element

5. The Neutral Element frame is reserved for the face you wish to draft. Click No selection from

the combo list and select the face as shown:

The application is going to detect the reflect line from this neutral face, and therefore the face that will be affected by the draft operation.

Pulling Direction

In the Pulling Direction frame, you can notice that the Selection field indicates

that a pulling direction has been defined by default as indicated by the arrow in the

geometry area. If you wish to change this pulling direction, you just need to click

the field and select the element of your choice as the new pulling direction.

● Note that contextual commands creating the pulling directions you need are also available from the Selection field:

❍ Create Line: For more information, see Creating Lines.

❍ Create Plane: see Creating Planes.

❍ X Axis: the X axis of the current coordinate system origin (0,0,0) becomes the direction.

❍ Y Axis: the Y axis of the current coordinate system origin (0,0,0) becomes the direction.

❍ Z Axis: the Z axis of the current coordinate system origin (0,0,0) becomes the direction.

If you create any of these elements, the application then displays the corresponding icon in front of the Selection field. Clicking this icon enables you to edit the element.

Parting Element

7. Click the Parting Element tab to define the parting element.

8. Check the Use parting element option and select Extrude.2 (the blue surface) as the parting

element.

9. Enter 0.1mm, if not already set, in the Parting Line Adjustment field.

This option adjusts the smoothness of the transition zone on the draft surface. A transition zone

occurs when a neutral element that was driving becomes driven, or vice versa. A zero parting line

adjustment would yield a sharp edge on the draft surface. Usually, the default value (0.1mm) is

most of the time efficient.

2nd Side

10. To define the other side to be drafted, click the 2nd Side tab.

Neutral Element

11. In the Neutral Element frame, click No Selection from the combo list and select the face as

shown:

Note that the reflect line of the face you selected as the first side is now displayed in pink.

12. Click OK to confirm. The part now looks like this:

Taking a closer look at the result, you can notice that both sides are adjusted onto Extrude.2.

In case you wish to know both angle draft values finally used to draft both sides of the part, you can use the Draft Analysis capability.

Filleting While Keeping an Edge

In this task, you will learn how to fillet an edge using a variable radius value and this without affecting another edge that would have been affected by the fillet operation.

1. Prior to filleting edges, hide Extrude.2 to improve the view.

2. Fillet a first edge to obtain at the end of the scenario a part ready for being removed from molds.

3. Click the Edge Fillet icon .

4. Fillet the the edge as shown using 4mm as the radius value and setting the Tangency

propagation mode.

You obtain this result:

4. To create the variable radius fillet, click the Variable Fillet icon .

The Variable Edge Fillet dialog box appears.

5. Select the edge as shown:

6. Click the point at the right extremity.

7. Enter 15mm in the Radius field to edit the radius value at this point.

8. Click Preview to get an idea of what the fillet will look like.

9. Click the point at the other extremity.

10. Enter 5mm in the Radius field to edit the radius value at that point.

11. Click Preview.

The preview lets you see that an edge is affected by the fillet. In the image below, the cursor shows you

this edge.

12. To preserve this edge from the fillet operation, click More from the dialog box.

You can access aditional options.

13. Click the Edges to keep field.

14. Select the edge you do not want to fillet. It becomes pink.

15. Click OK to confirm.

The variable radius fillet is created. The fillet is trimmed by the kept edge, as shown by the cursor:

16. Using the Graphic Properties capabilities, color the fillet to make it more visible.

The final part looks like this:
