Radius on curve

[krunoslav_knezic]

Hi all,

I was struggling to create some geometry on my latest project, and I would use your help.

I'm trying to create radius that will fallow curve on geometry.

Background

This curve is basically parting line where parts will be split in mold, so I want create radius that will fallow parting line in order to smooth design.

So far I tried sweep and loft, but without success.

Sweep create geometry, but radius isn't tangent on all geometry.

Loft is giving me trouble, but, also if I manage to create it, geometry is still not tangent on all sections.

Here is link to part

Can you enable the download option on the public link? I wasn't able to download the design, only view.

Have you tried adding G2 to the fillet options?

You may also consider taking advantage of the sculpt environment to get some nice smooth results! Check out this screencast:

I hope this helps.

Thanks,

Have you tried the varible fillet command?

[krunoslav_knezic]

Guys, thank you for your comments and suggestions.

PS I have made model download.

With both solutions I can create smooth tangent radius over geometry.

But what I'm trying to create is that the radius follow split line / plane.

This is important because of injection mold tools.

If radius goes above splitting line, I got undercuts on top part, and vice versa.

Here are additional images to explain.

Split plane with split line, but radius goes above split plane, making undercut for top part in mold.

Variable fillet gets quite close. If you need it better you could add more points, i've attached the file with my attempt.

Thanks for solutions!

I guess I was over thinking with control, that I missed this kind of simple solution.

This is why I love Fusion 🙂

Looking at the draft analysis it looks like there's still an undercut, I'm not sure you can get what you want if you need tangence with both surfaces.

Hi, here's one more attempt with loft. At the and I've picked wrong geometry for draft analysis, but that except that whole vid is ok. I've also attached f3d.

[krunoslav_knezic]

Yes, that's the complete solution I'm looking for.

Was trying also loft, but I was doing it with solid modeling, instead surface.

Thanks for the solution! 🙂
