Autodesk AutoCAD 2013 Practical 3D Drafting and Design


Overview of this book

AutoCAD is a computer-aided design (CAD) and drafting software application. AutoCAD supports both 2D and 3D formats. AutoCAD is used in a range of industries and is utilized by architects, project managers, and engineers, among others."Autodesk AutoCAD 2013 Practical 3D Drafting and Design" will take you beyond the 2D frontier and help you create accurate 3D models that simulate reality. This book is crammed full of creative and practical tutorials which will help you master the third dimension. From exercises on coordinate systems to creating solids and surfaces from 2D, you will wonder how you ever designed without this resource by your side."Autodesk AutoCAD 2013 Practical 3D Drafting and Design" is full of hands-on studies and projects that will help develop your 3D skills. Starting from the assumption of only a very basic knowledge of AutoCAD, this book will help you master 3D visualization and coordinate systems, create 3D models from 2D drawings, and from basic shapes, measure volumes, and other information, obtain 2D construction drawings from 3D models as well as how to apply lights and materials to get photorealistic images.

Editing with grips

If we select a solid or a surface without a command, grips are displayed depending on the type of object. Grips are the small blue squares (blue by default) that allow us to perform several editing operations.

On activating a grip, it turns red (by default) and we can move it elsewhere, thus changing the object. Let's see some examples:

  • Box: Activating one of the arrow grips, this allows us to adjust the length, width, and height; activating one of the square grips, it allows to change simultaneously length and width.

  • Pyramid: In addition to the box grips, we can control the top radius.

  • Extruded solid: We can change the source linear object as well as the height of extrusion.

  • Planesurf: With grips, it is only possible to move the surface.

  • Surfaces obtained from linear objects: We can adjust surfaces by moving any of the grips coming from the source linear objects. Additionally, with extruded surfaces it is always possible to adjust the height of extrusion.
