Feature sweep or loft?

62 Views, 6 Replies

Is it possible to sweep or loft a feature or part (or surface?)? Or are they
limited to sketches? I'm trying to represent a cutter path on a part with
different z-coords.

You can loft face to face but you need a sketch and path for a sweep. You
can extrude/loft a surface from a line/lines resp. As far as lofting
features, an extrusion face will loft but I don't think a hole will loft to
a face but you could loft a surface from a hole. Might help if you
elaborated somewhat on what you're trying to do.

Well, I was trying to help W. Holzwarth with the "Barrel Groove with Emboss
tool" problem (see this group and CF). I figured if I could sweep a hole feature
or cylindrical surface along a 3d sketch path, I could accurately cut the groove
he wants. But I don't think that's possible, is it? Then I was thinking I could
make a section of coil as the part of the cam slot that goes around the radius,
with a standard extrusion to make the straight section. Except I can't figure
out how to connect them. The edges don't meet-up exactly, so I can't fillet.

Yeah ... I think the problem is that the sketch profile doesn't rotate along
the path. If you split a sweep like that where it curves you can see the
walls aren't parallel. Charles posted a barrel cam a long time back, but I
don't know if it's still retrievable.

Hi again, Larry and Dave

I went into my task with the knowledge of Charles Bliss' barrel cam, but I
think it has the same difficulty. In Charles' example it was not obvious,
because the depth of the groove was not much. Only near looking could show
the problem, that's behind the Emboss thing there.

But it's somehow interesting. Thanks to you, Dave, Larry and Japper for your
inputs.
I'm still looking for myself, too, as it's mainly my thing to solve

I haven't tried it, but if I needed a barrel cam, I think the approach I
would take is a loft with rails. Seems likely that using that method it
would be possible to coerce the profile into rotating as it should along the
path.

This might work ... check it out. The root is curved but a faceted loft as
opposed to an extruded circle could probably be used to make the bottom
flat.
