Is it possible make Round fillet for this fin shape, as like in the 2nd screenshot? I want to make it without adjusting fillet dimension.
The only thing I can come up with Maha is to do an edge 6mm fillet. I noticed that picture you are trying to duplicate does not have merged faces on the loft. Also looks like there is a split along both sides. So I cut off both sides then Boundary Surfaces, knit to solid. then the fillet. Then added a couple of lofts on the sides. I imagine there is a better way to go about it but I was unable to come up with anything (not a fillet expert by any means).. It does look like you pick and the is a single line dividing the front and back.
I think these type of fillet has been intentionally made to mold easily. Otherwise fillet makes parting surface with combination of curved surface.
For this first picture you shared, try Dome feature as well. You may get results close to what you are looking for.
