I need to find the SW equivalent to the functionality of Pro-e and can't seem to find how to do it.

1) I need to be able to define points in 3D by typing them in (not reading from a file) so I can see and adjust the location of each point as I go

2) I need to be able to create a spline through the set of 3D points, defining the radius of curvature for each turn between (straight) curve segments

3) I need to be able to use the resulting 3D path as the centerline for a sweep

So far all I can find is a way to import 3D points from a file which is not practicle so can't even get started.  The curve through 3D points (even if I use a file to start it) has no functions to define the sements (straight or curved) or curvature between setgments.

Is there a usable command that I haven't found or is SW not capable of this kind of task?

Thanks - Greg
