Fillet what method best on this to a point and how?

Hi, V5 then V7, same failure in both.

Just what are the actual steps, to fillet this to a point in its two places needing it ?

Talk us all through it please. or a vid.

FilletEdge is nearest but bulges out a bit.
0.045 inch rad.

why cant we have an option to pick a point in the command ?

Fillet point.3dm (2.7 MB)

sorry if grid awful, attempt to follow McNeel fix on twisted ribbon lines using gamma 2.2 caused pale grid,a fix sees this.

Cheers

Hello- you can extend these two surfaces and do some trimming.

Hi,
Would that be filletEdge then trim or explode item, filletSrf, extend yes and trim yes ? then use those surfaces to trim ?

.and then knowing that, Is that always the way on such things where fillet needs to go to a point ?

Cheers

There is more than one way that fillet can end in a point, as you have recently demonstrated. You need to learn what is appropriate for each case.
In general, don’t use the trim option if you don’t understand the implications of using that option. You can always trim surfaces later. You have complained repeatedly about surfaces disappearing. That’s what happens when you use the trim option. The base surfaces get trimmed. If you don’t want that don’t use that.

Sometimes you use the extend option and sometimes not. It depends if the fillet naturally comes to a point on its own or whether come to a point because some other surface cuts across it at a diagonal. In this case the untrimmed fillet itself doesn’t come to a point. It only looks pointed at both ends after each end is trimmed by another surface.

The above only applies to answering your question about “where fillet needs to go to a point”. If you apply it for some other purpose it may not work.
