When I try to fillet, it tells me to select two faces to make it from, and while I hit ok, it makes just a copy without trimming the excess material. Why happens not to trim?
Which one to trim first? line 1, that goes along all the shape, or line 2?
For line 2 i believe that I can do a boolean after…
FilletSrf can only trim the two input surfaces if the edge of the fillet runs to the edge of the surface at both ends - it does not try to trim any but the two input surfaces. i.e. it is a surface level operation and not a ‘Solid’ operation like FilletEdge, which will try to trim the fillet surface into all of the surrounding faces of a polysurface.
