Creating a sketch plane in MultiSurf

In the image at the left the aft two master curves are in frames which allow them to be set at different angles by editing the Roll, Pitch, or Yaw angles of the Frame.

The points have their Dragging constraint set so they can only be dragged in the Y or Z direction, effectively locking them into the YZ plane of the frame.The procedure below gives you some steps to complete this construction.

Create a Frame from three points or a Roll/Pitch/Yaw Frame from one point and use this as a "sketching plane".
Put points in the frame and be sure to make the Frame the parent of the points. The points should be located in the x-y, x-z, or y-z planes of the frame. Depending on the plane in which the points are located, make the appropriate dragging constraint for all the points. This way the points can not be dragged off that plane with the mouse. Most kinds of curves will lie in a plane when all their control points do (Arcs, BCurves, CCurves, Lines, FCurves...)
You can hide the construction entities when the curve is done.
