Curvature Continuity

[D.Smith]

Hi I have this part that I modeled, but I don’t like the transition from radius to flat. Is there a way to make this a seamless transition (G2/G3 curve)?

Thank you

Is there a way to make this a seamless transition (G2/G3 curve)?

Yes. You could remove the fillet and replace with a surface with desired continuity using BlendSrf.

Thank you that worked, I have another question. How would I go about removing the flat spot in the model so that it’s seamless?

Thanks.

Like this?

For that you need to _ShrinkTrimmedSrf the surfaces and _UntrimAll, then you can _MergeSrf Smooth=no

Note this will create a single surface, but the surface will contain kinks at the merged locations.
Why do you need these surfaces to be merged?

Would you be able to upload that file that you edited? I wanna compare it against mine to see if there is really much change to modify the flat spot.

Thanks

Removing that seam is not going to make it ‘seamless,’ it would be best if that flat spot just wasn’t truly flat, if you’re concerned about making it look as smooth as possible.

@D.Smith

upload that file

I only merged the bigger surfaces…

if you must have it continuos: make 2 cut planes, intersect, sweep 2 with the resulting curves use add slashes at the quadrants.

note, one seam will stay, you can not get rid of that.

Okay thank you!
