An introduction to AutoCAD 3D Tools

AutoCAD is widely known and utilised as a 2D drafting tool. However, its use for 3D modelling is not as prevalent. This post introduces AutoCAD users to some of the most common 3D tools in AutoCAD by creating the simple shape shown below.

Before we start modelling, we need to change the workspace to “3D modeling” from the status bar at the bottom of the application. The ribbon will update to show 3D tools.

You can start by navigating to an isometric view by clicking on a corner of the view cube on the top right of model space. If you do not see the view cube, you can make it visible from the ‘View’ tab of the ribbon. Launch the 3DPOLY command to draw a closed 3D polyline in the front view (XZ plane). Starting on the origin and with ortho mode on (F8), start drawing as you would in a 2D view, keeping in mind that if you specify coordinates, you will need to provide them in all three axes.

Select the EXTRUDE command from the ‘Home’ tab of the AutoCAD ribbon, pick the 3D polyline from the previous step and then type 90 as the height of extrusion to create a 3D solid. You can control the visual style from the top left corner of model space.

Draw a triangle using a closed 3D polyline as shown below and extrude it to the back of the shape. You may find the ‘Extension’ object snap useful to find the vertices of the triangle.

At this point, we have two independent solids that intersect. Pick the UNION command and then select them both to combine them into a single object.

To finish the shape, draw a rectangle on the top face and extrude it to the base. Using the SUBTRACT tool, select the solid to subtract from first, press <Enter>, and then select the solid to subtract.

I hope you found this quick introduction to the 3D tools in AutoCAD useful. If you would like to learn more about this topic, you may want to consider our AutoCAD 3D Drawing and Modelling training course.

CAD and PLM: Why It’s the Solution for Manufacturing and Engineering Companies

29 July 2025

Efficiency, accuracy, and innovation are crucial for staying competitive in the industrial landscape of today. Manufacturing and engineering companies face increasing challenges in managing product development, ensuring design accuracy, and optimising workflows. That’s where Computer-Aided Design (CAD) and Product Lifecycle Management (PLM) come into play.

PLM Implementation Best Practices

29 July 2025

Implementing a Product Lifecycle Management (PLM) system can be transformative for any manufacturing or engineering organization, but success doesn’t happen by chance. It takes careful planning, collaboration, and the right tools. In this article, we’ll walk you through what PLM implementation involves, why it’s critical to your organization, the benefits it delivers, and the best practices to follow. We’ll also touch on common challenges to avoid, expected timelines, and how Sovelia Core can support your implementation journey.

PLM vs ERP: What's the Difference?

29 July 2025

Manufacturing companies today need robust systems to manage their operations and product development efficiently. Two of the most important systems in this regard are Enterprise Resource Planning (ERP) and Product Lifecycle Management (PLM). While they serve different purposes, both play a crucial role in streamlining business processes, improving collaboration, and enhancing overall productivity.
