Circular feature pattern 1

[adymech1]

I need to make an array of 7 holes along a circular path (it's difficult to calculate the radius of this path). I am unable to use circular feature pattern as I don't know the angle between 2 holes. I only know the vertical and horizontal distance of the holes from a datum. Calculating radius/angle would be cumbersome. How can I do this ina simpler manner.

Thanks to all who read this.

I think one way is to draw a sketch with the dims from a datum that you know. Draw a circle thru the points and you will have the radius. Now go to your hole and array per the radius. Hope I made sense.

Another way to skin the cat: Have you tried curve driven pattern?

Create the points from the data as in "ctopher's" suggestion. Instead of using a circle sketch through those points, try a spline. Use that spline sketch as the curve to drive a curve driven pattern.

You will probably want to select equal spacing. This should place the pattern in relation to the points placed for the spline construction.
