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.

Part Model (Sheetmetal- Directional Pattern)
The Pro/E part database is different when you create parts using Pro/SHEETMETAL. 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.
