Reverse a rounder-over

I created a round-over using the chamfer tool. Left the app and now need to reverse that round-over. Reselecting the edge and trying to reverse does not bring the edge back to flat. Is there a way to do this that I am missing?

Try selecting the fillet edge and deleting it.

You tried undo and selecting the filleted face and deleting it?

Undo does not seem to work after you close and re-open the app. And deleting the face results in a “Wound won’t heal” error.

Hi!

Could you show us a screenshot / video?

The chamferted/filleted face should be delete-able by selecting it and pressing delete, even after app restart. I suspect another face causing the issue with it.

This portion is 4 bodies aligned.

Here is the single body.

The left portion has a flat section just before the round-over begins, that face can be deleted. But when I try to delete the round-over and get back to just a flat face, delete fails.


I see, the problem is the multiple filleted faces, meeting eachother. That indeed cannot be deleted:

You can work around it by subtracting this part with another body to get the straight face you want, and offset it back to the correct size.

Perfect. Thanks!

Not sure if you tried this, but if you select all four chamfers first and then do the delete it might work.

Yes, also works, as long as he finds all the related faces. Nice tip!

I’ve had to do what TigerMike said with some internal chamfers on an enclosure I designed. Sometimes you just have to keep selecting chamfers/fillets until the delete works.

I also have a chamfer I can not change once done. If I click the now rounded face it jumps to Offset and if I click Chamfer it highlights ther perimeter.
Is this a bug? Happens at another place of the model also.

No, once created, it cannot be modified as a fillet. Since Shap3D uses direct modeling, once a face is created, it doesn’t retain the history of how it was created. In this case, it’s just a rounded face, not a “fillet” anymore.

The solution is to select and delete it, and apply the fillet again.

Laci, it can not be deleted that is what is bothering me and why I think it’s a bug.

here is the shapr file

The same happens to the opposite side of the clamp

In that case, you can cut off the unnecessary part, then use offset face.

Thank you Laci, that lets me go on with the model but looks like a workaround to me, to something that should be a simple delete? Just wondering how this happened and why this face behaves differently.

Currently we can’t heal the geometry in this case. If there would be even a small part of the original face left, it would be possible:

That’s worth remembering Laci, thanks. Leaving even a tiny bit of the original face gives us a way out :+1:
