_fllletEdge finds a precise Torus
_filletSrf just approximates it - this will give precision issues for later steps.
it would be important that also _filletSrf finds the torus / revolve.
_filletEdge without trim/join also does not give a torus / revolve

Depending on your needs at the time, both of those seems appropriate.
What am I missing?
I am also curious about this?
Why does FilletSrf give us “just a surface” and FilletEdge surface of revolution?
Hi all- As I recall, FilletEdge was cleaned to make revolves where possible but evidently FilletSrf not - I will add this to the pile.
RH-75374 FilletSrf: Simplify to revolves
-Pascal
Above example is taken from this years fillet exercise I asked my students to do.
Same course / test as last year - old exercise see here.
if the surface is build as revolve the intersection works nice: green curve until (x).
if the surface is build as approximation by _filletSrf (what many students did) the intersection and trimming does not work in some cases: red curve not hitting (x) but an edge.

A well implemented test for a revolve / torus will give much better results for the next / dependent modelling steps an handle tolerance in a much more “economic” way. (my guess…)
hope this explains the background of my wish - kind regards - tom
@John_Brock
did my explanation / example convince you ?
@pascal
any update on this topic ?
this seams not been worked on, even if filletSrf got an (UI-) Update for V8
@menno
will you become the new fillet-Expert ?
Here is another very basic example, inspired by the Tangent Cylinders wiki example
I use this to introduce my students for “Pointy fillets”
with a correct torus / revolve rhino is able to find the target point (x)
with the approximated _filletSrf result not
thanks for some action in the field of fillets - and hopefully you can bring some early results maybe in some testcommand… “_testFilletSrfV9” “_testFilletEdgeV9”
kind regards -tom

thanks @Tom_P I added that file to the YT
I hope to grow into that role yes, as @chuck’s retirement is approaching.
