Pattern holes

Create a point on the curve at either real length or length ratio, create a point normal plane axis, create a coaxial hole, create a group of the three (point/axis/hole) and use the group pattern function to pattern the hole, using the initial point offset as the driving dimension. You could even use a relation to determine the initial offset by how many pattern members you'll create on the curve. We could certainly get more complicated than that with an analysis datum feature and Pro/PROGRAM to take input.

Thanks a lot David. That was helpful.
