3D CAD with Autodesk 123D summary

Exploring the Basics of 3D CAD

In 3D CAD with Autodesk 123D by Jesse Harrington Au, we begin our journey into the world of 3D computer-aided design by exploring the basics of 123D Design, a free software from Autodesk. The author introduces us to the interface and provides a step-by-step guide on how to create our first 3D model. We learn about the various tools and functions that help us manipulate shapes, sketch lines, and create solid forms.

Au emphasizes the importance of understanding the fundamentals of 3D modeling, such as working with grids, planes, and axes, and the significance of precision and accuracy in our designs. Through practical exercises, we get to explore different techniques for creating simple objects, gradually moving on to more complex shapes and designs. The book encourages hands-on learning, with exercises and projects to reinforce the concepts learned.

Utilizing 123D Catch and Meshmixer

Continuing our exploration, 3D CAD with Autodesk 123D introduces us to 123D Catch, a software that allows us to create 3D models from photographs. We learn how to capture real-world objects or scenes using our smartphone or digital camera and convert these images into 3D models. The author illustrates the process through a detailed case study, guiding us on how to capture, process, and refine the 3D model of a real-world object.

Next, we delve into Meshmixer, another software in the 123D suite, which enables us to refine and manipulate 3D models. Au walks us through the various tools available in Meshmixer, showing us how to combine multiple models, sculpt organic shapes, and repair models for 3D printing. We learn how to use these tools to enhance our designs and overcome common challenges encountered in 3D modeling.

Creating Organic Shapes with 123D Sculpt+

Our journey through 3D CAD with Autodesk 123D continues with a focus on 123D Sculpt+, a digital sculpting tool that allows us to create organic and freeform shapes. The author guides us through the sculpting process, teaching us how to start with a basic shape and gradually refine it into a more intricate design. We explore the different sculpting tools available, such as push, pull, smooth, and flatten, and learn how to use them effectively.

Au provides practical tips and techniques for creating complex organic shapes, such as characters and creatures, using 123D Sculpt+. We also discover how to combine our sculpted models with other 3D designs, leveraging the interoperability of the 123D suite. The book encourages experimentation and creativity, empowering us to bring our imaginative designs to life.

Bringing Designs to Reality with 123D Make and 3D Printing

In the final section of 3D CAD with Autodesk 123D, we explore 123D Make, a software that helps us turn our digital designs into physical objects. The author introduces us to the concept of digital fabrication and demonstrates how 123D Make can generate 2D cutting patterns from 3D models, allowing us to create physical prototypes using various fabrication techniques.

We then dive into the world of 3D printing, learning about different 3D printing technologies, materials, and best practices. Au provides valuable insights into preparing our 3D models for printing, including optimizing geometry, setting up print parameters, and troubleshooting common printing issues. We conclude our journey by bringing our digital designs to reality through 3D printing.

In summary, 3D CAD with Autodesk 123D by Jesse Harrington Au offers a comprehensive and hands-on exploration of the Autodesk 123D suite, empowering us to unleash our creativity and design prowess in the realm of 3D modeling and digital fabrication.
