I am trying to add an unknown number of holes at random locations up and down a pipe.  Because of the geometry of the pipe, I cannot simply use the Part Hole Feature.  I'm trying to use the Part Extrude Feature and I'm lost as to how it actually works.

In the assembly design I have 

Child pipe_1 as ipe

End Child

In the pipe design I have:

Child Hole As :IvPartExtrudeFeature
    distance = 2
    operation = :cut
    extentDirection = ositive
    sketchPart = pipe_1
    sketchName = "Sketch7"
    face = "XY Plane"
    origin = "Center Point"
    xAxis = "X Axis"
End Child

In the Sketch7 I have a circle drawn in space without any reference lines crossing through the circle.

I'm getting the error "No such rule 'pipe_1' (parameter) "

I'm not sure what I'm doing wrong.

Is there a better way to add the holes to my pipe?

OK.  sketchPart cannot reference the part I am trying to cut a hole in.  Therefore, I needed to create an .ipt file with a sketch of the profile that I wanted to cut out.   my code now looks like this :

Child HoleSketch As :HoleSketch
visible? = False
End Child

Child Hole As :IvPartExtrudeFeature
distance = 10
operation = :Cut
extentDirection = ositive
sketchPart = HoleSketch_1
sketchName = "Sketch1"
face = "XY Plane"
origin = "Center Point"
xAxis = "Y Axis"
End Child

good luck
