3D sweep?

I am a recently new user of pro/e working on wildfire release. I have
no problems doing a sweep with a 2d trajectory but I can't figure out
how to make it with a 3d trajectory without using an equation. I
tried to make sketches in 2d (not in the same plane!) and even if I
link every end point of a sketch with an other sketch, it doesn't
work. I can't make it work with more than one sketch! I find it
quite easy to do with Catia but with pro/e... So if anyone could
answer me, I would appreciate!
Thanks
Vince

As you might have figured out, Pro/e does not have 3d sketching capabilities.
There are, however, a lot of ways to make 3d trajectories and two, in particular,
that sweeps will follow. The first kind of trajectory is created at the
intersection of two sketched curves (or surfaces). The two base curves are drawn
on adjacent planes, each is projected normal to the sketch plane and a third curve
is created at the intersection. When you have the two base curves sketched, you
can create the interesecting curve with 'Edit>Intersect' in Wildfire.

Another way to create a 3d curve that a sweep will follow is as a 'Thru points'
curve. The type of curve is not a spline but single (or multiple) radius with
straight sections that make a bend at each point. This is selected in the 'Curve
points' definition, along with the radius size which determines the radius at the
bend. If I'm not mistaken, the Sweep feature really needs the radiuses and ones
that will prevent it from collapsing in on itself. It doesn't take sharp turns
gracefully.

There are several other features that will let you sweep or blend from one set of
geometry to another. Some use trajectories, some, like the blend between sections,
do not. This latter is often called 'lofting' in other software. One of the better
ones that can use just about any type of trajectory is the swept blend. It's only
restricition is that blending geometry at each section entity must have the same
number of vertices. Another, the variable section sweep, can follow and vary the
section along several trajectories.

The pipe feature can also be used if the profile is a simple circle.

You mean 'Insert>Advanced>Pipe' and picking a bunch of datum points without
creating the curve first? Is this feature available without the Pro/PIPE module?

David Janes

 

Yep, that's the one.
(Insert>Advanced>Pipe in WildFire or Feature>Create>Pipe in 2001).

I don't think you need Pro/PIPE... not certain exactly which modules we
have here. Perhaps we do have Pro/PIPE. Is there an easy way to check
(other than asking our administrator or PTC rep)?

Yeah, go to 'Help>Technical Support Info', there will be a section on Configure
Option Modules that will list every module on your system, including floating
ones.

Yup, no Pro/PIPE, but also, no telling what kind of license, what license
'package' this comes with or in what module it actually resides. For example, does
this pipe feature come with the 'Foundation Advantage' license or do you need to
get one of the more upscale (e.g., Engineering II) license packages. Maybe a sales
guy could tell from this list what the package was, but I can't. And there online
propaganda doesn't help either. The most simple things seem to be the most
cultishly obscure and difficult to find anything out about.

David,

I have a Foundation II package and although the license file does not list
Pro/PIPE, I still have access to the Pipe command.
Arlin's listing is for a package somewhat more extensive than Foundation II,
though. Just for comparison, here is what you'll see in a Foundation II
license file:

Some additional info regarding Pro/E's Swept Blend and Variable Section
Sweep functionality is that you can blend from a section containing several
vertices to a sharp point--which is defined in the Swept Blend's sub-section
as a Sketcher 'Point' entity. The Variable Section Sweep can have its
cross-section height, for example, driven down to a point using a
pre-existing datum Graph feature. Powerful functionality! You can generate
geometry beyond your wildest imagination using the Variable Section Sweep
feature in Pro/E.
