Datum Curve Two Projections

It is often necessary to produce a datum curve that follows a profile in one direction and a different profile in another direction.

This can be accomplished by producing two extruded surfaces and then producing a curve using intr surf (intersecting surfaces) options.

The disadvantage is that the model can soon become a jumble of construction surfaces.

The alternative is to use Create, Datum, Curve, 2 projections. The method below avoids having to create the construction surfaces.

The two projections method requires two sketches to be produced (not in the same plane) the resultant datum curve is the intersection of the two sketches when projected normal to the sketching plane.

Pick the first sketch plane. Regenerate click done.

Pick the second sketch plane. Regenerate click done.

The resultant curve should be produced.
