AutoCAD 3D Tutorial Básico: A Step-by-Step Guide for Beginners

AutoCAD is widely known as a powerhouse for 2D drafting, but its 3D capabilities are equally robust—and often overlooked by beginners. If you’ve mastered the basics of 2D drawing and want to step into the world of three-dimensional design, this AutoCAD 3D tutorial básico is for you.

In this guide, you will learn the fundamental concepts, tools, and workflows to create your first 3D models in AutoCAD. No prior 3D experience is required. Let’s dive in.

What Ana Learned (And You Will Too)

  1. 3D modeling starts with 2D sketches.
  2. Extrude gives height.
  3. Subtract cuts holes.
  4. UCS lets you draw on any surface.
  5. Visual styles help you understand depth.

Your turn: Try building the same stepped block. It will take 10 minutes. After that, you’re no longer a 2D-only designer. You’re ready for real 3D.

Transitioning from 2D drafting to 3D modeling in AutoCAD opens up a new dimension of design possibilities, allowing users to visualize projects with depth and realism. This guide provides a foundational overview of the "AutoCAD 3D Tutorial Básico," covering essential workspace setup, core modeling commands, and navigation techniques. 1. Setting Up the 3D Workspace

To begin 3D modeling, you must switch your environment from the standard 2D view.

Workspace Switching: Change the workspace from "Drafting & Annotation" to 3D Modeling or 3D Basics using the gear icon in the bottom-right status bar.

View Adjustment: Use the ViewCube or the top-left viewport controls to switch from a "Top" view to an Isometric view (e.g., SW Isometric). This allows you to see the Z-axis (height).

Visual Styles: Change the visual style from "2D Wireframe" to Shaded or Realistic to see your 3D objects as solid forms rather than line skeletons. 2. Core 3D Modeling Commands autocad 3d tutorial basico

Most 3D objects in AutoCAD start as 2D sketches that are transformed into solids. AutoCAD 2026 - 15 MINUTE 3D Tutorial For BEGINNERS!

Switching from 2D to 3D in AutoCAD is a big step, but it’s mostly about learning a few new tools and a different way of "seeing" your workspace

Here’s a basic guide to get you started with 3D modeling in AutoCAD. 1. Set Up Your 3D Workspace

Before you draw anything, you need to change your interface to show the 3D tools. Workspace Switch: in the bottom right corner (or top left) and select 3D Modeling

. This will update your ribbon with 3D-specific tools like Extrude, Box, and Union. Change Your View:

(the cube in the top right of your drawing area) to click a corner, like Southwest (SW) Isometric . This lets you see the "height" of your objects. 2. The Core 3D Commands

Most 3D objects in AutoCAD start as 2D shapes that you "push" or "pull" into the third dimension. EXTRUDE (EXT): AutoCAD 3D Tutorial Básico: A Step-by-Step Guide for

Select a closed 2D shape (like a circle or a joined polyline) and give it a height. PRESSPULL:

This is often easier than Extrude. Just click inside any closed area, and you can pull it up into a solid or push it down to create a hole.

Takes a 2D profile and "spins" it around an axis to create things like bottles, bowls, or wheels. Australian Design & Drafting Services 3. Combining and Cutting (Boolean Operations)

Once you have multiple 3D shapes, you can combine them using these tools:

Merges two or more separate 3D objects into one single piece.

Uses one object to "cut" a hole out of another. Select the object you want to keep, press Enter, then select the object you want to use as the cutter and press Enter again. Australian Design & Drafting Services 4. Visualizing Your Work

By default, AutoCAD might show your 3D objects as "Wireframes" (just lines). To make them look solid: tab or look for the Visual Styles dropdown in the top left of your drawing area. Conceptual to see the surfaces of your model. Australian Design & Drafting Services Pro Tips for Beginners Join Your Lines: If you draw a shape with basic lines, use the What Ana Learned (And You Will Too)

command to turn them into a single polyline before extruding. This ensures you get a "solid" rather than just a hollow shell of lines. Use the Gizmo:

When you select a 3D object, colored arrows (the Gizmo) appear. You can click and drag these to move, rotate, or scale your object along specific axes. Practice with Primaries: Start by creating basic 3D "primitives" like found in the Create panel to get used to the 3D space.

7. Exportar e imprimir

1. Preparación y configuración

Union (União) - Ctrl + Plus (+)

Transforma vários sólidos separados em um único objeto.

Chapter 4: Cutting a Hole

The napkin showed a hole through the top step.

The cylinder vanished. A hole appeared.

Note: Subtracting is like carving away material.

Part 1: Setting Up Your Workspace for 3D

AutoCAD opens in the Drafting & Annotation workspace by default. For 3D, you need a different setup.
