Filleting edges in 3d Autocad will add a sense of realism to your built objects – we show you how in our Autocad 3d courses. 
Creating a filleted edge is a simple process, similar to filleting a corner in Autocad 2d. First create your objects as in the screenshot right. Then go to the Fillet tool, or hit F on your keyboard. Autocad then asks you to specify how to define the properties of the fillet. The most common would be the radius of the filleted edge: hit R for radius, then hit Enter. The Command line then asks for a radius value in mm – enter the value and hit Enter again. Then click on the edge or edges you wish to fillet, and hit Enter again.
Related to this is the Chamfer tool – follow the prompts in the Command line to chamfer edges either to a distance or an angle, resulting in a hard cutaway.
When you later add realistic materials such as metal with reflectivity, and then realistic lighting with shadows, the light will pick up the filleted or chamfered edges, thus adding a sense of real-world appearance to your scene.
The 3d interface in Autocad is user-friendly and easy to learn, and we take time to teach a broad range of applications in our classes including modeling, materials, lighting and animation. See many examples of our clients’ work on our Facebook page. For more information there are lots of resources on the web, but try the Autodesk site to begin with: www.autodesk.com. Support options and user forums are also available from the home page.
