Understanding fillets and chamfers

Fillets and chamfers are modifications that are made to the edges and vertices of our models. They help remove sharp edges and turn them into softer ones in order to provide a safer product or a better user experience. They are similar to fillets and chamfers in sketching. The following image illustrates the effect of the Fillet feature:

Note that fillets and chamfers can only be applied to existing features. In the preceding images, we explored the extruded boss feature first, and then we were able to apply fillets or chamfers. Also, to apply fillets and chamfers, we don't need to start with a 2D sketch. 

Now that we know what fillets and chamfers are, we can start using them in SOLIDWORKS.
