2001 spline curve: z values have been reset to zero

When reading a points file with z-values added i get the messsage:
"WARNING: z values have been reset to zero"

According to the help file PRO/FEATURE should be present to allow for
the change of z-values, which is.
rel. 2001 build 2003010

Can't find anything at PTC web site.

Does your license say you have Pro/FEATURE? ('Help>Technical Support Info') As
I've never seen a package of Pro/E without this 'option', I'd be very surprised if
you turned up an installed items list without it. So, once again, a help message
is not much help.

What I know about this is as follows: Two 'points' files come to mind. One, with a
PTS extension, contains x and y coordinates, relative to a sketcher cs, of points
on a section spline. The 'z' value is always 0 as the section is planar.

The other type of points file has an IBL extension. This one can be read to create
a curve using 'Insert>Model datum>Curve>From file', specify the coordinate system
and get the File>Open menu, listing the .ibl and any .igs files in the working
directory. This will create whatever spline curves are documented in the file,
with x, y, and z references for each point inthe curve entity.

Yes, Pro/feature is listed in the info window and following let me to
believe that using a 2D-spline can be used as a start for creating a
3D-curve:

Three-Dimensional Sweeps

With Pro/FEATURE, sweeps can be created along a three-dimensional path
with a three-dimensional spline for the sweep trajectory. That is,
Pro/FEATURE allows you to modify the Z-coordinates of spline points.
All other Sketcher entities must lie on a two-dimensional sketching
plane.

In all other respects, three-dimensional sweeps are created in the
same way as two-dimensional sweeps. For such applications as creating
springs, you can also create an advanced feature helical sweep by
sweeping a section along a helical trajectory.

And as the points list for a sketched spline is written with the
Z-values it seemed logical that changes to it are accepted.

Sure, granted, but if you're giving it a .pts file to create a 'Model
Datum>Curve>From file', it is expecting the format of an .ibl file. So, give it
either an .ibl file or a file inthat format. Did you get the example of the .ibl
format file I sent you? Were you able to read that and create splines using 'Model
Datum>Curve>From file'?

Corrrection: As of Wildfire, Pro/e seems not to recognize the .pts file extension
for creating a curve from file or for a sketched curve created by 'Sketch>Data
from file'.

This claim by the help file is suggestive, certainly, informative, maybe but
definitely uninstructive. What I would be expecting after this claim is a "How
to..." or "Modifying the 2d curve to make it 3d". I have Pro/FEATURE and am unable
to do as they suggest ~ not in sketcher with Modify and not out of sketcher with
Edit. The little suckers refuse to lift off the sketch plane. You can grab and
drag the end points which changes x,y dimensions, and you can adjust the
interpolation points in between, but that's it. Sketcher Modify doesn't even
provide z dimensions. So, at this point I'm skeptical it can even be done.

As to the substantive point you raised ~ creating a 3d sweep ~ this newsgroup has
recorded two successful ways, one with a spline and one without. The first
involves creating a curve from '2 projections', the second, used for pipe
trajectories, is to make a curve 'thru points' and instead of the 'spline' option,
to pick either the 'single' or 'multiple' radius. This creates a curve with
straight segments between points and bend radiuses for the sweep. The '2
projections' curve uses two sketched curves, projectts them normal to the
sketching plane and creates a resultant of the points of intersection between the
projections. This type, while awkward to use, is the only kind of curve trajectory
that can be a spline. A 'curve thru points' spline will not work. I'm not sure
about a curve created from an .ibl file.

Ahhh, the sketched CS! That's what I skipped. Thanks, Jeff, nice catch. Sometimes
those help files do come through.
