Autodesk Fusion CAD & CAM & SolidWorks CAD Basics (Crash)

Learn CAD Basics with Fusion 360 & SolidWorks: A Beginner's Guide to Product Design

Unlock the power of 3D design! This crash course provides a fundamental understanding of two leading CAD software options: Autodesk Fusion 360 and SolidWorks. Ideal for aspiring product designers, engineers, and manufacturers, this guide covers essential skills in modeling, assembly, and drafting.

Autodesk Fusion 360 Basics

Fusion 360 is a powerful, cloud-based CAD tool that streamlines the entire product development workflow – from initial concept to manufacturing.

• User Interface Overview:
  • Toolbar: Access tools for sketching, 3D modeling, and design management.
  • Browser: Navigate the design structure, viewing components, bodies, and sketches.
  • Timeline: Track the design process step-by-step.
  • Canvas: The primary workspace for visualizing and interacting with your designs.
• Creating a New Project:
  1. Open Fusion 360 and initiate a new design (File > New Design).
  2. Begin with a 2D Sketch to define the object's outline (Sketch > Create Sketch).
  3. Utilize basic sketch tools (lines, circles, rectangles) to create the desired shape.
• Basic Modeling:
  • Extrusion: Add depth to closed 2D profiles using the Extrude tool (Create > Extrude).
  • Revolve: Create symmetrical 3D shapes (like cylinders) by revolving a profile around an axis (Create > Revolve).
• Assembly: Combine multiple components into a single assembly (Assemble > New Component). Use joints to define the relative movement of parts.
• Parametric Design: Leverage Fusion 360's parametric capabilities to define dimensions and relationships between objects, allowing for easy adjustments.

SolidWorks Basics

SolidWorks is a robust CAD software renowned for its powerful parametric modeling features, particularly in mechanical design.

• User Interface Overview:
  • Command Manager: Provides access to all necessary tools for sketching, feature creation, assemblies, and drawing.
  • FeatureManager Design Tree: Displays the design hierarchy, including parts, assemblies, and features.
  • Graphics Area: The main area for viewing and manipulating your 3D models.
• Starting a New Part:
  1. Open SolidWorks and create a new part (File > New > Part).
  2. Create a 2D Sketch on a plane (Top, Front, or Right).
  3. Use tools like Line, Circle, and Rectangle to define the initial shape.
• Extrusion & Revolving:
  • Extrude Boss/Base: Add depth to a 2D sketch (Insert > Boss/Base > Extrude).
  • Revolve Boss/Base: Create symmetrical parts by revolving a profile around an axis (Insert > Boss/Base > Revolve).
• Creating an Assembly:
  1. Create a new assembly (File > New > Assembly).
  2. Insert parts into the assembly by selecting them and positioning them.
  3. Use mates (Insert > Mate) to define relationships and movement between parts (e.g., coincident, concentric).
• Drawing for Manufacturing: Generate detailed manufacturing drawings from 3D models (File > Make Drawing from Part). Include views (front, top, side, isometric) and dimensions.

Key 3-Axis Milling CAM Features

Enhance your manufacturing capabilities with these essential CAM (Computer-Aided Manufacturing) features:

• Adaptive Clearing (High-Efficiency Roughing): Quickly and efficiently removes large amounts of material, optimizing tool engagement for extended tool life and reduced machining time.
• Contour Milling: Precisely finishes part perimeters using climb and conventional milling. Offers fine control over stepdowns and stepovers.
• Parallel and Scallop Finishing: Ideal for achieving smooth finishes on curved surfaces. Parallel moves create a back-and-forth motion, while Scallop maintains a consistent cusp height.
• Pocketing: Efficiently clears cavities and pockets. Supports both 2.5D and true 3D pocket strategies.
