can't solve chamfer problem...

Hi Michael and all,

i have a part which i can't chamfer at all. I need it with the chamfer value of 0.1
I tried to rebuild as lofted model and also tried other approaches. but all failed.
The only thing one time i got was a joined surface part, but i need a solid, so that
i can 3D print it. I have many similar parts, which i could solve with Rhino eval. etc.
but this is the only part from the whole model where i get stuck.

Any help how to solve this chamfer problem would be greatly appreciated!

Regards
Stefan

Hi Stefan,
I'm not sure what the problem is, but it looks like to many naked edges.
I would rebuild it like so.

1. Re-create the two profiles.
2. Run "Planer" on the poly-line piece
3, Trim that with the oval.
4. Extrude that.
5 Create two curves and boolean diff, removing the top and bottom pieces.
6. Run the Chamfer tool.

Works for me.

Hi Scott,

thanks for your reply, much appreciated! Unfortunately your technique does not work. I attach a picture
which shows the difference with your approach. I must learn more about this naked edges issue and how
to solve this, in case if this is the problem.

Regards
Stefan

Guess I was a little late.
Here is take two, where instead of creating two curves, you create two fairly large spheres, positioned slightly apart to account for the thickness you need.
Use one sphere and run Boolean Diff.
With the other, run a Boolean Intersect.

I began with that approach eddi, but then stopped after having the other rebuild idea.
Nice solution!

Hello,

Your construction lines are a little out of square (Align is your friend), also try moving the egg shaped seam to the midpoint of a larger face.Those construction lines have a crazy amount of points, for clarity I rebuilt and aligned, and it chamfered fine, even with or without straight edges enabled. I have some time for a video if needed.

Stefan, here is another complementation for Ostexo's tut... for rebuilding top surface.
Clean and fast with Box, Isect, Network

Envelop with box


Use Isect, after delete all solids


Cleanup and use Network


Trim and shrink

Oh, that's a great way to avoid those seam lines at all! Thank you very much for showing this Eddi!
Will be very helpful in the future.
