Difficult fillet

puzzle 005.zip (631.5 KB)

Hi All

I’m trying to figure out a simple way to fillet all the inside corners.

Does anyone have ideas?


Hi paul - it will be hard to work with this object - it is just too complex and messy for the shape



There are places with zero-thickness -

I say this needs a re-think and clean-up.


I’m not sure where I went wrong.

I’ve worked with it flat, slicing up a surface, extruding all the surfaces, cutting them up in layers and finally booleaning the interlocking parts together.

I’m stumped.

@pascal is right, what he can do is draw the upper curve and correct the error that indicates pascal in the image 1
Then use the ExtrudeCrv command, then create a loft between the curves that I have indicated colors, but before you make a fillet a bit larger than the outline fillet and split the solid with the surfaces.
there is an area that gave me problems
what I did was cut it where I pointed and do the FilletEdges separately.strong text

Sorry for not uploading the file but I forgot that the solid had a curved cut on the bottom, I made the entire splice without making the cut :sweat_smile:

I see where you are going with this.
Thanks for your suggestion I’ll give it a try.

Did you have any problems doing the fillet curves after you created the square outlines of the future loft curves?

yes, in fact at the corner where I mark, I had to split in two parts to create the fillet without problems, and the piece with very closed angles was made with sweeps


I’ve been able to clean it up more .

This piece is saying there are 12 naked edges,but for some reason they won’t appear for me.

Hi Paul - use ShowEdges > Naked edges to see this - the Zoom function in that tool helps. My general feeling is still that the modeling here is a bit messy - there are surfaces that are in the range of .001 units or less, across and for some reason the file tolerance is set to .00001 mm. There should be no reason to model this at lower than .001mm and the very smallest feature or surface should be 10X that at the very smallest.


I think you just need to be a couple of notches more careful in how you arrange the surfaces and even then, make a careful inspection of the geometry when you’re done.


I nknow the area of which you speak as I was lofting there to be Aable to join everything. I did use the show edges and zoom commands, but I have to tell you that my screen is not revealing any naked edges at all. I believe it’s still open and this must be a glitch in the program.
I Was hoping that winging it with the lofts might do the trick, but I’m going to have to trim some material off the bottom part near where it connects to the top and try another loft. I am dissapointed that depite my trynig to get all the parts accurate b efore I did a flow along curve, I see that that command won’t deliver the results I need. The shapes curved and they also got a little out of shape at the ends so they would no longer fit together perfectly. Was I wrong to think that flow along curve would deliver the top parts accurately to meet the 4 shank pieces under them?


I have imported the initial file to avoid any problem other than the configuration
you can use the FlowAlongSrf command and then with the DupEdge command, extract the outline of the sides and create the sweep of the bottom.

Thanks for the advice. I was also thinking along those lines.
