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.

3D solid primitives


The 3D primitives are solid basic shapes like boxes, cylinders, spheres, and others. We can also apply a special solid primitive to create walls in a similar way as we create a polyline.

Accessing all these commands, besides digitizing their names or alias, can be done on the ribbon, Home | Modeling panel, on the Modeling toolbar, and on the Draw | Modeling Menu bar:

The creation of these solid primitives, like most commands in the previous chapter, is dynamic, that is, upon specifying one or more points or dimensions, we see the objects being formed.

Note

For most basic shapes (with the exception of POLYSOLID), we can use the PROPERTIES palette (Ctrl + 1) to change dimension parameters after creating the solid.

To improve the visibility of curved faces in non-wireframe visual styles, we may apply the FACETRES variable. A value of 2 or 3 is normally enough. With wireframe visual styles, we may apply the ISOLINES variable to increment the number of lines used to represent...
