Can someone tell me what are the methods for 3D constraint in sketches?

I almost always create 2D sketches to control my 3D sketches.  Can you attach a sample file that you are having trouble with?

I am doing a simple pipe run but I don't know how to use the constraint to make the lines parallel to the Axis.

I assume you are not using Inventor Routed Systems with the piping module.  You need only create 2D sketches with points dimensioned for the bend intersections.  Then create 3D sketch with bend activated to do your path.  The advantage to this method is it is trivially easy to edit.  What release of Inventor are you using?  Perhaps I can work up a quick example.
