cannot add sketch fillet

darren_mason871

I made this L shape out of lines. Then I selected a plane, tapped pencil, tapped sketch fillet, tapped a corner, and I got the error: cannot add sketch fillet. What do I need to do different?

Hi,

First guess is you have a small part and the default fillet size is too large to regenerate. 

If you post a link to the doc someone will be able to take a real look rather than taking a guess

The sketch fillet is failing because it defaults to 5mm in size. If your lines are shorter than that it will fail. On desktop you can click and drag a fillet to size. Embarrassingly, I can’t work out how to do it on mobile so I will ask someone who does. In the meantime, can you make your lines temporarily longer in order to add the fillet? You should also consider adding your fillet as a model feature after the sketch has been extruded. As a rule of thumb, only add fillets to a sketch if it is a functional requirement- if it’s just to break a sharp edge, add it as a model feature.

The description sounds as you are trying to add a sketch fillet in a sketch feature different from the one in which lines were sketched. It would only worked for the lines sketched in the same sketch.
