Exercice 1a

First Wall Features

Objectives

At the end of this exercise, the user should be able to:

Create a new file using sheet metal type;

Create first wall features of sheet metal parts using the following options:

Extruded wall

Flat wall

3. Convert a solid model to a sheet metal model.

Designing in Sheetmetal Mode

Introduction

In my numerous years of CAD and MCAD experience, I have yet to see software as

sophisticated as Pro/ENGINEER Wildfire Sheetmetal mode. The enhancements done to

Wildfire 2.0 are simply amazing. Finally, a software package that thinks as an engineer

or designer would.

Sheetmetal mode allows a designer to perform many sheet metal features. Examples

would be:

Introduction to Pro/ENGINEER Wildfire Sheetmetal

Feature creation in Sheetmetal mode is quite different from Part mode. While some of

the Part mode features (described as solid features) can be accessed from the Sheetmetal

mode menu, other features can be created, and all are related to sheet metal design.

The model building philosophy can also be quite different. Again, while some aspects of

Part mode are integrated within the Sheetmetal environment, one thing is always true: “If

you don’t put any thinking into your first (base) feature, you will run into trouble at some

point in your modeling process.” Needless to say, sheet metal parts should be well

thought of ahead of time before the first feature (first wall) is created.

Bends (Angles, Rolls) and twists and rolls

There are numerous ways in which a sheet metal user can create a first wall option in

Sheetmetal mode. The options are:

In Sheetmetal mode, by creating an extruded section;

In Sheetmetal mode, by creating a flat wall;

In solid type Part mode, by creating a thin section, then converting it to sheet

metal.

The following table gives a review and description of the basic wall feature types

available in Pro/ENGINEER Wildfire 2.0.

Wall Feature Type

Description

Extruded

A sketched 2D profile with an offset wall thickness. Bend

angles can be built into the 2D profile as in Project 1 (similar

to Pro/ENGINEER’s Thin Wall Protrusion)

Flat

A sketched boundary in a 2D plane (flat) at a specified bend

angle (Similar to Pro/ENGINEER’s Extrude Protrusion)

Extended

Creates an extension of a wall surface to another wall surface,

usually at a comer.

Revolved

The cross-section of a revolved wall is sketched and rotated

about an axis (similar to Solid mode Revolved Protrusion)

Blended

The cross-section of the blended wall is sketched, with other

options such as parallel, rotational and general.

Offset

An offset sheet metal wall is created by offsetting from an

existing solid surface.

While extruded and flat are the most common first wall features used, the other features

prove to be quite useful in many applications.

Procedure

We need to first get organized before beginning the training files. A working directory

needs to be created for locating all training files created in this manual. Most, if not all,

files will be created from scratch, and will be used for more than one exercise. Using

your browser, create a folder named ‘sheetmetal_1’ in the location of your choice.
