Curve->Free Form->Interpolate On Surface  (Keep "snaps" off) 

Also look at Curve->Offset->Offset Normal To Surface

	and 	

	      Curve->Offset->Offset Curve On Surface


Now Turn on Perp and End "snaps"


MEA: 8/2/15

Rhino v5.0 is now load. This file has been auto-tranlated to 5.0 tool.

v4_PerfumeBottle_Solid now has a curve drawn on the surface.

I use "Curve->Offset->Offset Normal To Surface" with offset "5" to create the second curve.

Now using Tools->ObjectSnap->End turned on, connect each endpoint to the two curves with a line using "Curve->Line->Single Line".

Using "Curve->Line->Perpendicular To 2 Curves", draw a third line between the center of the curve drawn on the surface and the curve that is offseted.

Using "Properties Tab | Details" select each line and note the there length. All three say "line length = 15".



MEA: 10/3/15 This what we want to use instead of the PerfumeBottle image. We are drawing on an actual KURBS patch.
             (The PerfumeBottle is a MESH object)

Go to menu Render->Shade to create solid surface.
