datum planes tangent to non-cylindrical..

[BNC06]

Hi all,


I need to set up some datum planes that are tangent to a non-cylindrical surface (an airfoil) at specified points on the surface.


The purpose of this is to be able to drill holes perpendicular to the surface of the airfoil for static pressure ports.


Any help is greatly appreciated.

with your point create a datum axis >tan curve


it will ask for the curve ... then a point... you now have a axis tangent to the curve


create a datum plane thru the axis and normal to the plane the curve lies on


then you can create a second plane normal to the plane you just created and thru the point


as long as you point truely is on that curve you should be able to move it around


you may want the original point to be on the curve as point>on curve >length ratioand if you need a xy value you could create a analysis featureView attachment 1074

Worked great, I think my problem was that I was trying to use a curve (an edge of the solid) that the points were not on. I just sketched a datum curve using the offset function in sketcher with a value of 0 since I was in the plane containing the points (the original edge was .5" away).


Thanks!!!!!
