Boolean Union failure

I have tried everything I can think of to union these objects. It fails every time. Any thoughts?

For me Union works for all except for three (adding them individually singles the failing ones out).

Try move the failing ones slightly, and then they will also Union.

As Rolf has pointed out, where the proximity of the pips coincide with the edge of the shape is part of the problem, I’d try to tidy up the pips and make them a little simpler (not less detail but a cleaner model)

Are you using the FlowAlongSrf command for this? Probably the easiest way. You can extract the surface and use the CreateUVCrv command to create the shape and then offset the edge by a fraction or make sure they are overlapping the edge as an example.
