Draw a tube using XYZ coordinates

Question

I have a set of 4 XYZ coordinates through which I would like to draw a line, then sweep the line to create a non-planar tube. Maybe there is a better way to do this? It seems as though it should be simple to import points, drawing a line chain through the points, and then sweep the line. Help? I'm using Creo Parametric 3.0 M040. I don't have the Piping module.

POINT	X	Y	Z
1	0	0	0
2	0	0	4.54
3	0.72	-3.01	4.40
4	4.91	-10.83	4.38

Disclaimer: I am using Creo 2, but I doubt that this has changed in Creo 3.

Use Point - Offset Coordinate System to create your points. If you enter the first point, then you can click on the "Update values" button, then copy and paste your coordinates into the text editor. Save, exit, and your points will be populated in the dialog. Complete the point feature.

The short way to create your tube: Search for the Pipe command (use the magnifying glass at top) which isn't on any ribbons but still exists, and you don't need Pro/Piping to use it. It uses the old-style Menu Manager, but I think if you play with it a little bit you will understand the options quite quickly.

A slightly longer, but more flexible way to create your tube: First create a Datum Curve through Points. The UI for this is the new ribbon style. The options are similar to what you see in the pipe command, but there are more options you can explore (to control tangency etc.). When the curve is complete, you can simply create a sweep using the curve as your trajectory and sketching any section you like.
