Intro to 3D Modeling Lesson 2 - Autodesk



Introduction to 3D Modeling

Abstract

Introduction to 3D modeling is a beginner level CAD course focusing on easing the transition from 2D to 3D design skills, using Autodesk Fusion 360 CAD CAM. The course includes introductions to industry standard 3D modeling techniques and skills and covers four main types of 3D modeling in Fusion 360. These are Sketching and Parametric modeling, Freeform modeling and sculpting, Direct modeling and Assembly Modeling.

Whether you are a designer, engineer, machinist, maker, artist, teacher, student, or just plain curious, this course will help you to take your first steps and make the transition to professional 3D modeling. Through a series of easy to follow video tutorials and 3D modeling exercises, the course will equip you with the necessary professional competencies required for 3D modeling and design.

Introduction to 3D Modeling

The main aim of this course is to help ease the learning transition from 2D design to 3D modeling. 3D modeling using CAD is a superb additional skillset for any product designer, engineer, or machinist and being able to use Fusion 360 CAD/CAM will enable you to take an excellent idea from a concept, through to a working 3D CAD model for manufacture, testing and production.

Fusion 360 and Autodesk Design Academy provide extensive learning resources which make it incredibly easy to use CAD and learn how to 3D Model. Furthermore, Fusion 360 is free to students and educators, works on both Apple and PC operating systems, on multiple devices and platforms.

If you are looking to make the transition from 2D to 3D modeling -- this course has been developed to guide you through the process and have you up and running, developing design for professional 3D models after a few short lessons.

Lesson 2: A Simple Exercise: modeling from 2D sketches to a 3D CAD Model

Watch this video series to create a simple 3D CAD model in Fusion 360.

After completing this lesson, you will be able to:

? Use Fusion 360 to sketch a 2D CAD Model, using simple parametric tools, such as lines, rectangles and constraints.

? Create a simple 3D CAD model in Fusion 360, using simple tools such as extrude and Fillet.

? Use the timeline to edit model features and dimensions.

? Use the Documentation Environment in Fusion 360 to create technical drawings and output

in various formats.

Tutorial Video 1: How to sketch and edit simple 2D rectangles using lines, constraints and Centre Rectangle.

After completing this lesson, you will be able to: ? Use Fusion 360 to sketch and edit simple 2D CAD Models, using simple parametric tools, such as lines, rectangles and constraints.

Step 1: Create new design.

1. Click File > New Design.

2. Click to flick through the tabs at the top and note that we can have multiple files open in Fusion 360.

Step 2: Sketch four lines and add constraints to create a rectangle. 1. Click Sketch > Create Sketch.

2. Click to select plane to work on.

3. Note when we are in the Sketch environment, the Sketch Palette will launch. The Sketch Palette includes both Options and Constraints.
