help me for create advanced surfaces (Swp sez var blend sweep)

what the command in pro/e for create surface whit 2 rail? (rhino 3d)

Thanks Fabio

If you are in Wildfire, the command is 'Insert>Variable Section Sweep' or in 2001,
'Insert>Surface>Variable Section Sweep'. One 'rail' (in Pro/e jargon, a
'trajectory'), called the Origin Trajectory, needs to be selected first. It is the
one that the section will stay normal to. The other trajectory(s) control the size
and shape of the section. It depends on the sketched section geometry just how
much control can be exerted over its size and shape. Sketches composed of splines
are the most variable and controllable; sections with conics are the next most
variable or anything with 'soft' dimensions controlling lengths and angles of
straight geometry. Geometry that is completely nailed down, with hard dimensions
and constraints, is least variable.

.....Variable Section Sweep ...

Hi, David.
This might be a good suggestion. Rhino's Sweep2 command is actually more
like a Swept Blend using two trajectory curves, but there are no section
plane definitions (the "sections" don't even have to be planar curves).
Pro/E doesn't have an equivalent function that I know of, but one of the
other functions may work out if VSS doesn't fill the bill.

Fabio,
If you can't get what you need and can make the curve set available,
holler back.

Seems, from your description, Jeff, that a boundary blend surface might be as
close as Proe comes. Or, for that matter, ISDX can do the same thing with non
planar 'sections'. I guess we've got a little Rhino built into Pro/e.

Yeah, all of them have their uses and none of them is directly equivalent to the
functions in other programs. When I wanted to compare the result and operation of
doing a feature in SolidWorks using their 'Sweep with guide curves', with the same
in Pro/e, I had to use a VSS, nothing less would produce equivalent results. While
I could have done it with boundary blend surface and produced the tangency I
wanted, it would have been much more cumbersome and time consuming. But you're
right in suggesting trying different ways of doing the same thing. Experimenting
is a good way to rapidly get the modelling experience and be able to compare
within and between modelling packages.
