Fillet via sketch vs fillet via modify vs fillet via CAM?

[Anonymous]

What is good advice for when to define a fillet where? I presume that there are upsides and downsides to each, but being a newbie to this, it's not very obvious to me. Thanks.

Generally, it's best to fillet a 3d model. It is parametric, which makes it easier to change. Fillets in sketches can be dimensioned, however changing the radius can have unexpected results depending on other constraints (most of which are unnecessarily added automatically). I prefer to use fillets in sketches even though it's not the best way to do it. If you are going to use CAM, then you may not need to model the fillet.
