How to Make 3D in AutoCAD 2017?

Switching from 2D to 3D in AutoCAD 2017

To start working in 3D in AutoCAD 2017, follow these straightforward steps:

1. Open AutoCAD: First, launch AutoCAD on your computer and open your existing 2D drawing or start a new project.

2. Locate the View Cube: Navigate to the top right corner of the drawing area where you’ll find a 3D View Cube icon.

3. Adjust the Viewpoint: Click on the cube and drag it, ensuring that the top, right, and front faces of the cube are visible. This action will change the perspective from 2D to a 3D view, allowing you to visualize the dimensions and depth in your model.

4. Enable 3D Modeling Workspace: For efficient 3D modeling, switch to the 3D Modeling workspace. You can do this by clicking on the Workspace Switching icon in the status bar at the bottom and selecting 3D Modeling from the dropdown menu.

Creating a 3D Shape in AutoCAD

To create a 3D shape, follow these steps:

1. Choose the 3D Modeling Workspace: Make sure you are in the 3D Modeling workspace, which provides options tailored for three-dimensional design.

2. Select the Solid Tab: Click on the ‘Solid’ tab in the ribbon. This tab contains all the tools necessary for creating solid geometric shapes.

3. Utilize the Extrude Feature: Locate the Extrude command within the Solid panel. This tool allows you to convert 2D shapes into 3D objects. Click on it.

4. Select Your Objects: Click on the 2D objects or edges that you want to extrude into the third dimension. Be certain to select all relevant contours.

5. Specify the Height: After selecting the objects, you’ll be prompted to enter the height for the extrusion. Type in the desired height or drag the mouse to define the distance visually.

Exploring 3D Modeling Types in AutoCAD

AutoCAD supports numerous methods for 3D modeling, each designed for specific tasks:

• Wireframe Modeling: This foundational modeling technique allows you to create an outline of your object, serving as a guideline for more complex structures. It’s particularly useful during the design phase for visualizing proportions and layout.

• Solid Modeling: Solid modeling represents objects as complete three-dimensional entities, allowing for accurate mass properties calculations and visualizations of how they will behave in real-world conditions.

• Surface Modeling: This technique focuses on creating complex shapes by manipulating surfaces rather than solid volumes, enabling designers to create intricate forms like car bodies or architectural facades.

Essential Commands for 3D in AutoCAD

Understanding key commands can greatly enhance your efficiency in creating 3D models:

• 3DMOVE: To move 3D objects, you can click on the 3D Move option from the Modify panel or type 3DMOVE directly into the command line.

• 3DROTATE: To rotate 3D objects, access the 3D Rotate command from the Modify panel or enter 3DROTATE in the command line.

• 3DSCALE: Scaling 3D models can be done using the 3D Scale option, accessible in the Modify panel or by typing 3DSCALE.
