Now that you have downloaded AutoCAD for free, you might be wondering how to use it for 3D modeling and rendering. 3D modeling is the process of creating a digital representation of an object or a scene using geometric shapes, curves, surfaces, textures, colors, lighting, etc. Rendering is the process of generating a realistic image from a 3D model using various techniques, such as shading, shadows, reflections, transparency, etc.
In this section, we will show you some of the basic and advanced tools and commands that you can use in AutoCAD to create stunning 3D models and renderings. We will also give you some tips and tricks that will help you improve your skills and efficiency.
Basic 3 Basic 3D Modeling Tools and Commands
One of the first steps to create a 3D model in AutoCAD is to switch from the 2D drafting workspace to the 3D modeling workspace. You can do this by clicking on the gear icon at the bottom right corner of the screen and selecting 3D Modeling from the list. You can also use the command WORKSPACE and choose 3D Modeling from the options.
Once you are in the 3D modeling workspace, you will see a different set of tools and commands that are designed for 3D modeling. You will also see a 3D view cube that allows you to change the orientation and perspective of your model. You can also use the View tab on the ribbon to access various 3D views, such as top, front, right, isometric, etc.
Some of the basic tools and commands that you can use to create 3D models in AutoCAD are:
Box: This tool allows you to create a rectangular box by specifying two opposite corners or by entering the length, width, and height. You can access this tool from the Home tab > Modeling panel > Box icon or by typing BOX in the command line.
Cylinder: This tool allows you to create a circular cylinder by specifying the base center point, radius, and height. You can access this tool from the Home tab > Modeling panel > Cylinder icon or by typing CYLINDER in the command line.
Sphere: This tool allows you to create a sphere by specifying the center point and radius. You can access this tool from the Home tab > Modeling panel > Sphere icon or by typing SPHERE in the command line.
Cone: This tool allows you to create a cone by specifying the base center point, base radius, height, and top radius. You can access this tool from the Home tab > Modeling panel > Cone icon or by typing CONE in the command line.
Pyramid: This tool allows you to create a pyramid by specifying the base center point, base radius, height, number of sides, and top radius. You can access this tool from the Home tab > Modeling panel > Pyramid icon or by typing PYRAMID in the command line.
Torus: This tool allows you to create a torus (a doughnut-shaped object) by specifying the center point, major radius, and minor radius. You can access this tool from the Home tab > Modeling panel > Torus icon or by typing TORUS in the command line.
Wedge: This tool allows you to create a wedge (a triangular prism) by specifying two opposite corners or by entering the length, width, and height. You can access this tool from the Home tab > Modeling panel > Wedge icon or by typing WEDGE in the command line.
Extrude: This tool allows you to create a 3D solid or surface by extruding a 2D object along a path or direction. You can access this tool from the Home tab > Modeling panel > Extrude icon or by typing EXTRUDE in the command line.
Revolve: This tool allows you to create a 3D solid or surface by revolving a 2D object around an axis. You can access this tool from the Home tab > Modeling panel > Revolve icon or by typing REVOLVE in the command line.
Sweep: This tool allows you to create a 3D solid or surface by sweeping a 2D object along a path. You can access this tool from the Home tab > Modeling panel > Sweep icon or by typing SWEEP in the command line.
Loft: This tool allows you to create a 3D solid or surface by lofting (blending) two or more 2D objects. You can access this tool from the Home tab > Modeling panel > Loft icon or by typing LOFT in the command line.
Advanced 3D Modeling Techniques and Tips
If you want to create more complex and realistic 3D models in AutoCAD, you need to use some advanced techniques and tips that will help you improve your skills and efficiency. Some of these techniques and tips are:
Use solid editing tools: Once you have created a basic 3D shape, you can use various solid editing tools to modify it further. For example, you can use Fillet Edge to round off sharp edges, Chamfer Edge to bevel edges, Shell to hollow out a solid, Slice to cut a solid along a plane, Presspull to extrude or cut a face, and so on. You can access these tools from the Solid tab > Solid Editing panel or by typing the corresponding commands in the command line.
Use Boolean operations: Another way to modify your 3D shapes is to use Boolean operations, which allow you to combine, subtract, or intersect two or more solids. For example, you can use Union to join two solids into one, Subtract to remove one solid from another, Intersect to create a solid from the common volume of two solids, and so on. You can access these tools from the Solid tab > Boolean panel or by typing the corresponding commands in the command line.
Use 3D grips: A useful feature that can help you edit your 3D models faster and easier is the 3D grips, which are small handles that appear on your objects when you select them. You can use these grips to move, rotate, scale, or stretch your objects without entering any commands. You can also use the multifunctional grips to access more options, such as aligning, copying, mirroring, or arraying your objects.
Use parametric constraints: If you want to control the dimensions and relationships of your 3D models more precisely, you can use parametric constraints, which are rules that define how your objects behave and interact. For example, you can use geometric constraints to specify how your objects are aligned, parallel, perpendicular, tangent, etc. You can also use dimensional constraints to specify the exact measurements of your objects, such as length, radius, angle, etc. You can access these tools from the Parametric tab > Geometric panel and Dimensional panel or by typing the corresponding commands in the command line.
Use 3D subobjects: Another way to edit your 3D models more efficiently is to use 3D subobjects, which are the individual components that make up your solids or surfaces. For example, a box has six faces, twelve edges, and eight vertices as subobjects. You can select and modify these subobjects separately by using the Subobject Selection Filter or by pressing Ctrl while clicking on them. You can also use the Subobject Selection Settings to control how subobjects are highlighted and selected.
How to Render and Export 3D Models in AutoCAD
After you have created your 3D models in AutoCAD, you might want to render them and export them to other formats. Rendering is the process of applying materials, textures, lighting, shadows, reflections, and other effects to your 3D models to make them look more realistic and appealing. Exporting is the process of saving your 3D models in different file formats that can be used by other applications or devices.
Some of the tools and commands that you can use to render and export your 3D models in AutoCAD are:
Materials Browser: This tool allows you to browse and apply various materials to your 3D models. You can choose from a library of predefined materials or create your own custom materials. You can also adjust the properties and settings of your materials, such as color, transparency, reflectivity, bumpiness, etc. You can access this tool from the Visualize tab > Materials panel > Materials Browser icon or by typing MATERIALS in the command line.
Lights: This tool allows you to add and manage different types of lights in your 3D scene. You can choose from point lights, spot lights, directional lights, ambient lights, etc. You can also adjust the properties and settings of your lights, such as intensity, color, attenuation, shadows, etc. You can access this tool from the Visualize tab > Lights panel > Lights icon or by typing LIGHT in the command line.
Cameras: This tool allows you to create and manage different types of cameras in your 3D scene. You can use cameras to define the viewpoint and perspective of your 3D models. You can also adjust the properties and settings of your cameras, such as lens, target, clipping, field of view, etc. You can access this tool from the Visualize tab > Views panel > Cameras icon or by typing CAMERA in the command line.
Render: This tool allows you to render your 3D models using various options and settings. You can choose from different render presets, such as draft, low, medium, high, etc. You can also customize your render settings, such as resolution, quality, exposure, background, etc. You can access this tool from the Visualize tab > Render panel > Render icon or by typing RENDER in the command line.
Export: This tool allows you to export your 3D models to different file formats that can be used by other applications or devices.
