Hi @dmitriy
Thanks for sending the file over! I found that I ran into errors when trying to create all the fillets in a single feature as well. I did notice that I had no problems adding the omitted edges into the original feature after it had been created, in your file as well as in a new file. Saving the file as a new version also allowed me to add the fillets into the original feature from the design timeline.
As this behavior is inconsistent (Fusion can generate fillets between all the desired selections but will not when all the fillets are selected initially), I have logged a report (FUS-36572) with development, who will be working to improve this behavior. I believe that this may be due to the fact that, when all the fillets are selected, the cylindrical face the teeth are coming out of is fully split be the new face, as new faces fully intersecting the cylindrical face are created with this feature. I found that splitting the cylindrical face on both sides of the teeth allowed me to select all the desired edges initially with no errors in all files I tested this in, as shown in the screencast below.
Please let me know if you have any questions!
