Using the Chamfer/Fillet tool, you can create two different types of chamfers: basic and 2-distance. The basic chamfer is a 45-degree, sloped transition between adjacent surfaces or faces. On the other hand, the 2-distance chamfer is a sloped transition that is not necessarily 45 degrees; you can customize the blend by specifying where the newly created edges should end.

1. Go to Tools > Chamfer/Fillet.
2. Select the type of chamfer.
   “Auto” creates basic chamfers and “2-Distance Chamfer” creates 2-distance chamfers.
3. Select the edges you want to chamfer. If you select a face or body, all connected edges will be automatically selected. 
   
4. If you’re in “Auto” mode, pull the selected edges to blend them. The chamfer length is a negative value.
   If you’re in “2-Distance Chamfer” mode, pull the selected edges once; you’ll see two equal distances measured from the edges you selected. Then, drag each set of arrows to adjust each distance. 
   
   
5. Select the dimension label to define exact values of the chamfer. You can type in the exact value and press the Return key to finalize the dimension. 
   
   
6. Select Done to finish.

   If the edge you adjusted on a 3D body has other continuous edges, all those edges will also be blended. 

Adjust chamfers

You can always fine-tune the chamfer by selecting the chamfered edge and changing the dimensions. Once you chamfer an edge, you cannot change it into a fillet without completely deleting the chamfer, and vice versa. To delete it, just select the chamfered face and select Delete or press the Delete key.

💡Shortcut💡: If you select the edges first, the menu is customized automatically. From this adaptive menu, go to Chamfer/Fillet. 

When you're done blending the edges, click anywhere in the design space to confirm the change.
