Course Notes - Computer-Aided Design (Siemens NX) 4472

Semester Project

Objectives The semester project is designed to allow the student to demonstrate the ability create accurate solid models within a 3D CAD modeling system, as well as to demonstrate the ability to work with other in teams. Furthermore, this project is designed to give students experience in documenting technical data through both graphical, written, and...

NX Unit 1

Siemens NX is a powerful 3D CAD tool that serves as the backbone of modern design and engineering processes. In this introductory exploration, we will delve into the fundamental concepts that form the core of NX, beginning with an understanding of its basic workflow. We'll explore the "Master Model" approach, which emphasizes the importance of...

NX Unit 2

This section builds on the concepts from Unit 1, guiding you through the process of creating a model from a working drawing. You'll learn how design intent influences the structure of a model and gain practical experience with the drafting workflow. Additionally, this section will introduce you to the master model concept, providing a clearer...

NX Unit 3

This section introduces the concept of parametric modeling and the use of expressions to drive design parameters. Key Concepts Parametric Modeling Expressions & The Expressions Editor Design Features Holes Threads Edge Blends (fillets & rounds) Chamfers Datum Features Point Axis Plane Datum CSYS Pattern Feature Polar Array Count, Pitch, Span Assignment - Parametric Fuel Tank...
