How to 3D sketch not on a plane
(OP)
How can I 3D sketch, so the sketch is not on a plane? I am trying to sketch a wire that goes from one place to another in 3D space using the top down (in assembly) method. I am going from "near" one part to "near" another part. In Inventor or Pro-E I would create work points at the intersection of 3 planes, a plane and an axis, etc... and create the 3D sketch by going from one point to the next. I have done this in SW by going from one sketch point to the next. I would like to create work points (which seems to be a SW weakness, although I can create work axis and planes just fine)and go from one point to the next or free sketch the line and use relations to tie the end into 3 planes to locate it. Is there a way to do this? Am I missing some way easier to do this?

Perhaps use two separate 3D sketches? One for key points (I also include construction lines for wire direction at key points), and the second for your actual wire.

Another question. Is there a way to make a segment of the spline between two spline points perfectally straight? I can do it by stopping the spline sketch.....then sketching a straight line between two sketch points.....then starting up the spline and finishing. But being able to just pick a segment you want straight would be easier.

A question regarding the statement in the previous post about making the lines and arcs concentric with existing features. Does this just mean having an arc concentric around a round post or is there more I am missing?
Thanks again

You can create the sketch with in-context relations. Then when you reopen the part to edit the sketches and create the sweep, you can break the relations if your company doesn't allow in-context relations to other parts. Many companies don't allow this due to being burnt in the past by having parts change unknowingly if another part changes.
I'll create a quick example of what I'm talking about.
