Tutorial 3: Shells, Ribs, and Datum Planes

Introduction

Datum planes are used as sketching surfaces and references for creating and construction features. In this section, you will learn to use

datum planes to create a rib. You will learn how to create several basic features.

Creating Base Shape

Start Pro/E Wildfire.1.

Select [File] -> [New], and type the part name [Example3] in Text Box.2.

Click [OK] Button.3.

Select the Extrude Tool icon from the tool bar at the r ight of the screen.4.

Select the Sketcher icon from the dashboard, and click the reference plane marked as FRONT.5.

Click the Sketch button from the Section menu. Pro/E will switch to Sketch Mode.6.

Close the References dialog box.7. Select [Sketch] -> [Options] from menu bar. Turn ON the [Grid] and [Snap To Grid], and click the green check button.8.

Select [Sketch] -> [Intent Manager] from the menu bar.9.

Use pan and zoom operations to change the viewing so that you see the coordinates as shown in Figure 3.1.10.

Now sketch the shape of the cross-section shown in Figure 3.1. Select [Line] from the Menu Manager GEOMETRY menu. Click points

A, B, C, D, A with the left mouse button, and then press the middle mouse button.

[Figure 3.1]

11.

Select [Regenerate] from SKETCHER menu.12.

Now set dimensions as shown in Figure 3.2. Follow the steps below.

Click Edge1 and Edge3 with the left mouse button, and click point A with the middle mouse button.

Click Edge2 and Edge4 with the left mouse button, and click point B with the middle mouse button.

Select [Regenerate].

Modify dimensions to match those shown in Figure 3.2 if necessary, and Select [Regenerate].

Using Datum Planes to Create a Rib

Select Datum Plane Tool icon from the tool bar at the right of the screen, as shown in Figure 3.10.

[Figure 3.10]

1.

Select the center axis of the circular protrusion. Hold CTRL and select Edge1 shown in Figure 3.11. This will define references for the

datum plane so that the plane passes through the axis and is normal to the edge.

[Figure 3.11]

2.

Select OK on the Datum Plane pop-up window.3.

Select Datum Plane Tool icon again.4.

Select the center axis of the circular protrusion. Hold CTRL and select Edge2 shown in Figure 3.11.5.
