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.
To see the hole clearly:
Real objects are rarely perfect blocks. They are the result of adding, subtracting, or intersecting shapes. AutoCAD handles this through Boolean operations: Union, Subtract, and Intersect.
These operations allow you to build highly complex parts from simple beginnings. autocad 3d tutorial basico
Pro tip: Start with 3D Basics—it has fewer tools, making it less intimidating.
Let’s create a simple solid box from scratch. AutoCAD is widely known as a powerhouse for
The most significant hurdle for beginners is the User Coordinate System (UCS) . In 2D, you only have X (horizontal) and Y (vertical) axes. In 3D, you add Z (depth/height). The UCS icon shows you which plane you are drawing on. By default, you are on the "World" XY plane (the ground).
To draw on a vertical wall, you must move the UCS. Type UCS , then FACE . Click on the side of your box. The UCS icon will realign itself to that vertical surface. Now, if you draw a circle or a rectangle, it will be drawn on the side of your block, not the top. After finishing, always type UCS then W (for World) to reset your coordinate system. Mastering UCS is the single most important skill for efficient AutoCAD 3D modeling. To see the hole clearly: Real objects are
Só desenhar não basta. É preciso cortar e unir. Aqui estão os dois comandos mais importantes:
