  It's much simpler to construct a plane in FeatureScript with opPlane than with cPlane.  If you want to make a line-angle plane using cPlane you will need a Query for a linear edge, a Query for another reference entity, and angle at which to offset from the reference entity.  It will require a lot of trial and error to get the directionality of the angle correct, and probably won't work in the generic case.
  
  What sort of inputs do you have?  It's very easy to make a plane with opPlane as long as you know a point in your plane and the normal of the plane.

  simple is good! 
  I have 1 line, 2 endpts of the line, midpt of the line  and the plane normal to line.
  I would like to create different planes along the line.

  Sounds like you could just do:
  
  

  opPlane(context, id + "plane1", { "plane" : plane(endPointPosition1, normalDirection) });
  opPlane(context, id + "plane2", { "plane" : plane(midPointPosition, normalDirection) });
  opPlane(context, id + "plane3", { "plane" : plane(endPointPosition2, normalDirection) });
  

  to create the three planes.
  
  Not sure if when you say you have a line and its endpoints, you're saying you have a Line and 2 Vectors or if you have Querys for all three of those things.  If they're Querys, you can do the following:
  
  

  var endPointPoisition1 = evVertexPoint(context, { "vertex" : endPointQuery1 });
  var normalDirection = evEdgeTangentLine(context, { "edge" : lineQuery, "parameter" : 0.5 }).direction;
  etc...

  it doesn't seem to work.
  plane needs origin,normal & x , correct?

  Plane has a number of interfaces.  For your purpose, the x direction doesn't actually matter, so the `plane(origin is Vector, normal is Vector)` should be sufficient:

  Can you post a screenshot of how it's not working?
