Looks like things are coming along well Brian, thanks for posting the pics!

In order to ease the selection of the proper set of vectors in Aspire, so as to create two different toolpaths, it is helpful to save two different PDF versions from one MoI drawing.

The CNC spoilboards are attached by 48 bolts, with 1/4 inch holes, and 5/8 inch diameter countersinks.
The curve vectors for the 1/4 inch holes are circles in MoI, with style set to Blue.
The curve vectors for the 5/8 inch countersinks are also circles in MoI, with style set to Red.

Using Top View in MoI:
Hide the Red circles, and save the Blue circles to BlueHoleVectors.PDF.
Hide the Blue circles, then unHide and save the Red circles to RedCountersinkVectors.PDF

In Aspire:
Import the BlueHoleVectors.PDF into Aspire to one Layer.
Import the RedCountersinkVectors.PDF into Aspire to another Layer.
Hide the Red Layer, then select the Blue circles with a mouse selection box, and create the DrillBlueHoles toolpath.
Hide the Blue Layer, then unHide the Red Layer, select the Red circles with a mouse selection box, and create the PocketRedCountersinks toolpath.

This method avoids having to individually select 96 curves by clicking on them.

@ Brian -

Those parts turned out really nice.

Off topic question:

I have a CNC Mill, but with only 2" of X travel. It's for jewelry only and very precise. With a rotary table occupying the X table I can't use it for other purposes.

Are you open to fabricating one-off small 2D pieces in plexiglass or Delrin if the MoI drawing is provided?

If so we can connect offline for details. I'm near Seattle.

Sorry Ed, I'm not in the business, just a hobbyist :-)
