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
Pick the first sketch plane. Regenerate click
Pick the second sketch plane. Regenerate
The resultant curve should be produced.
