So the holes in my part do not act like typical holes and I cannot mate to them any other way than tangent or lock mates which i don't want. The holes in the part were made before the flex feature.
As Dan Pihlaja mentioned.. Reference geometry and sketches comes in handy here. Especially a reference point center of face. In this example I added 3d sketch lines with one end coincident with the ref points and perpendicular to the curve in order to align the axis of the grommet.
You have a screen capture you can share?
here is the part I'm trying to mate to.
Can you use the Temporary axis for the holes for a concentric mate? You will need to turn them on so they show first. Depending on how severe the Flex, you may need to create a special configuration of your grommet to match the curvature of your part.
i tend to stay away from mating to temporary axes. I find mating to them, quite an unstable process.
This is where reference geometry and reference sketches come in. You can mate them together.
Yes, typically this is what I do, I utilize planes and axes to position components.
For cases like this make a sketch block of a equilateral triangle and sketch the center point. You need a 3D sketch. Make any of the 3 points coincident with the deformed hole edge. That gives you now a good center point position. It depends on you deformed hole how much this point can vary depending on the point locations. But most of the time this is sufficient.
