Introducción A Los Conceptos Básicos En Autocad 2010

This tutorial outlines the procedures for creating three-dimensional objects by creating basic
3D shapes known as solid primitives. You can also create 3D models by extruding 2D shapes.
Audience: Users new to 3D modeling with AutoCAD 2011
Prerequisites: Working knowledge of 2D drafting
Time to complete: 15 minutes

Lesson 1: Create 3D Solid Primitives
In this lesson, you learn how to create 3Dsolid primitives in the 3D Modeling
workspace.
You can use standard 3D solid objects known as solid primitives to create a
box, cone, cylinder, sphere, torus, wedge, and pyramid. To create these 3D
solid primitives, switch the workspace to 3D Modeling, where the palettes
and ribbon panel are customized to create and modify 3D solid models.
Switch to the 3D Modeling Workspace
1 On thestatus bar, at the bottom of the drawing area, click the Workspace
Switching button.
2 On the Workspace menu, click 3D Modeling.
The 3D Modeling workspace is displayed. In this workspace, you can access
the various commands and tools needed for creating 3D drawings.

NOTE For more information about switching workspaces, see the AutoCAD User’s
Guide or refer to theAutoCAD 2009 tutorial: Switching Workspaces in AutoCAD
2009.
Create a box
You can create a rectangular or cubical solid box. Box objects can form a basic
structure that you can resize or combine with other objects.
The following steps explain how to create a box.
1 On the ribbon, click Home tab ➤ View panel ➤ Visual Styles drop-down
➤ Conceptual.
2 On the ribbon, click Home tab ➤ Modelingpanel ➤ Solid Primitives
drop-down ➤ Box.

3 At the prompt, click any point in the drawing to specify a base point.
4 At the prompt, enter @ 8,8 for the opposite corner and press Enter.
5 At the prompt, enter 5 for height and press Enter.
The base of the box is always drawn parallel to the XY plane of the current
UCS (workplane). The height of the box isspecified in the Z axis direction.
You can enter both positive and negative values for the height.
6 On the ViewCube, located at the upper-right corner of the drawing
window, click Top, Front, Left, and Right to navigate around the sheet.
NOTE For more information on ViewCube, see the AutoCAD User's Guide or
refer to the AutoCAD 2009 tutorial: Navigating a Model with ViewCube.
Create acylinder
You can create a cylinder with a circular or elliptical base.
4 | Create Basic 3D Objects
The following steps explain how to create a cylinder.
1 On the ribbon, click Home tab ➤ Modeling panel ➤ Solid Primitives
drop-down ➤ Cylinder.
2 At the prompt, click any point in the drawing to specify a base point.
3 At the prompt, enter 5 for radius and press Enter.
4 At the prompt, enter 8 forheight and press Enter.
Create a cone
You can create a pointed or frustum of a cone with a circular or elliptical base.
Lesson 1: Create 3D Solid Primitives | 5
The following steps explain how to create a cone.
1 On the ribbon, click Home tab ➤ Modeling panel ➤ Solid Primitives
drop-down ➤ Cone.
2 At the prompt, click any point in the drawing to specify a base point.
3 At the prompt,enter 7 for radius and press Enter.
4 At the prompt, enter 5 for height and press Enter.
Create a torus
You can create a ring-shaped basic 3D solid primitive that resembles the inner
tube of a tire. A torus has two radius values. One value defines the tube. The
other value defines the distance from the center of the torus to the center of
the tube.
