Hi sayd, one other thing that can happen with fillets is that they won't be generated if there isn't room for them to fit.

Sometimes it is easy to mis-judge what size will fit. So if you are running into problems you might try dropping the fillet radius down in stages, maybe try a smaller value like 0.1 or 0.05 and see if those work, and then you can try larger values until you find the spot where it won't fit anymore.

If you have your original model that had the problem in it, can you please post it here? I can then take a look at it and see if there was something in the model that was preventing filleting from happening, or if it was a bug in the filleting.

Also, it would really make it easier to answer questions if you could post the .3dm model file with the objects that you are having problems with instead of just a screenshot - it is a lot easier to examine the model to see what is happening.

Problem solved michael, it somehow worked well when i tried it again.

Heres a screen. I made the metal closing but i deleted all the lines and circles so i had to do it new and well it didnt work out so i erased it. Will finish it sometimes. But this tutorial teached me alot.
