Hello, I am trying to make a fillet in this piece, with a radius of 7, but this gives me an error when selecting a complete line, I do not see that it is cut anywhere, but even so the program only allows me to apply a radius of one and with the mode constant. Attached images and the file.

Hi Avila, it can be not so good to make objects thousands of units across. If you scale down your object to a more regular size that can help.

To do that, select your object and run the Transform > Scale command.

At the first prompt where it says "Pick origin point" type 0 and push Enter, that will specify 0,0,0 as the scale origin.

Then at the next prompt type in 0.01 and push enter and that will scale your object to 1/100 of its original size.

You can then select that edge and put a fillet on of 0.07 units and it seems to be ok.

Hello, I have adjusted the scale of the model and I have also configured my grid better, I already solved it! Thank you very much.

I have continued practicing and now I have found myself with this problem again, I cannot apply any type of fillet in these lines.

Hi Avila, can you please post the .3dm model file? It helps a lot to see what is going on if I'm able to examine the actual geometry instead of only screenshots.

But based on your screenshot I'd say this is going to probably be a difficult corner juncture here:



It would probably be good if this edge was not there:



Also something like this probably isn't good because the fillet won't be able to trim the base object if it just abruptly ends without running into other faces or other fillets that it can be trimmed against:



I can try to give you some better information if you can post the model file.

Yes, well, actually, I want to apply a fillet to all those lines that remain of the model, only in the screenshots, mark those because that is where the problem lies, and I know that the problem is there, so I don't know how to solve it :)

Hi Avila, I got rid of that edge by separating out the surfaces on either side of it and doing an "untrim" (that's where you select the trim boundary edges and use Delete) then built a new revolve that had a profile curve that was a single segment so it would make one single face when revolved.

Then revolved and trimmed and joined.

Without that edge there it should be easier to make a fillet go throught there:

Hello, I am sorry for the ignorance, but I do not understand!

Hi Avila, well it is a simpler process if you have a version saved off with your original generator curves. Much of the process I described above is about untrimming the model to recover the underlying base surfaces from which generator curves can be extracted. There is a tutorial on these techniques here:
Object repair tutorial

But the goal of all of that is to get these generator curves:



Currently with that curve in 3 separate pieces when you revolve it it will make 3 faces, one for each segment:



The change that is needed is to make that curve made up of only one single segment instead of 3 segments, so that it will make one single face when revolved:



The combining can be done using the Rebuild command in v4 or the Merge command in v5.
