3D Offset or Scale or Extend???

I have a rectangle shape (a 3D polyline) as in the attached DWG. I want to Offset, Scale, Extend (call it whaever you wish) so that the new 3D polyline (after the scale, offset or extend) is at the same plane as the original one.


Obviously the Z values of the new 3D polyline will be different from the original.

The old trick, turn it into a block, insert x,y,z independently.

there is no offset-method within AutoCAD working on 3D-polylines, the chances I see (asuming that there is a realistic situation in the attached drawing):

a) as long as the geometry is flat you can create a UCS by 3 points from you 3D-poly, next set the view parallel to the UCS and start command _BOUNDARY ==> here you get a standard polyline that can be offseted.

b) you use Civil3D, so you have the chance to use the grading-tools, offset as distance without a slope.
