Lesson 13 Patterns Figure 13.1 Parts with Patterns OBJECTIVES Construct a fill pattern Create an axial pattern Model a sheetmetal part and create a directional pattern Use the Auto-Round Tool Patterns Creating a pattern is a quick way to reproduce a feature. A pattern is parametrically controlled. Therefore, you can modify a pattern by changing pattern parameters, such as the number of instances, spacing between instances, and original feature dimensions. Modifying patterns is more efficient than modifying individual features. In a pattern, when you change dimensions of the original feature, Pro/E automatically updates the whole pattern. This lesson will use direct modeling to introduce you to variations of the Pattern Tool. 535 Part Model (Plate- Fill Pattern) Click: OK Edit Setup Units Set OK Close Done File Rename Plate OK OK Tools

All sheet metal parts are by definition thin-walled constant-thickness parts. Because of this, sheet metal parts have some unique properties, which other Pro/E parts do not have. You may convert a solid part into a sheet metal part, but not a sheet metal part into a solid part.
