You can have the pattern start wherever you want if you create a small gap in the sketch at the start point. The first and last features will be on top of each other, so you have to add one to the number of instances. You can also disable one of the overlapping features if you want.
that is awesome to know! im going to delete my video tutorial and redo it with this information and give you credit in the video!
Steve & David,
The way I usually do similar parts is not to use the Curve reference, but to place a Datum Point on the Curve, pattern it using Dimension, reference pattern an Axis, then a Hole. You can measure the curve for spacing, or even use an Analysis Feature to control it. An easy sub-technique is to do one half of the Curve, use the Reference Pattern technique, then Mirror.
The illustration for the Jan. 1, 2009, post seems to have been lost with the new Forum interface. Just to give an idea of possible complexity, this shows a pattern on a Curve dropped onto a Boundary Blend Surface. Hidden are the Points and Axes that were patterned first in a chain of Reference patterning.
