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.

Cutting objects

Sometimes we need to cut 3D objects. Here is a command to perform this task. The PROJECTGEOMETRY command (presented later in this chapter), although not being its main function, also allows cutting 3D objects.

Cutting solids and surfaces

Here is the most used command to cut solids and surfaces.

The SLICE command

The SLICE command (alias SL) allows cutting solids and surfaces by a plane or an existing surface. We can maintain both parts or select one. We can also access this command on the ribbon, Home | Solid Editing, and on the Menu Bar, Modify | Solid Editing.

We start the command by selecting the objects to cut:

Command: SLICE
Select objects to slice: Selection

We have to define the cutting plane. By default, we define a vertical cutting plane, specified by two points:

Specify start point of slicing plane or [planar Object/Surface/Zaxis/View/XY/YZ /ZX/3points] <3points>: Point
Specify second point on lane: Point

Then, we specify a point to indicate which part we want...
