Alignment on Irregular Shapes

Can someone give me an idea of how to fixture and base align this part? I am used to doing parts with flat planes perpendicular to each other that I can use for the alignment, but this part does not have that. 

I was thinking I would lift the part on standoffs although I am not sure how I will square it up or keep it from spinning (side note, if anyone has a recommendation for fixturing items that you find versatile or game-changing, feel free to pass those along!) Then I was thinking I would combine the tops of the two "wings" into a single plane and use that as Z origin. But as far as X and Y origins, there are not any planes perpendicular to those that I could use. I thought about making a plane on the back side of the tail and another on the top ledge of the tail and creating an intersection line and using that as the X origin, but I that still leaves Y and clocking. 

I am just completely stuck right now, so any input you have will probably generate a bunch of follow up questions from me, but I would appreciate any direction you can give.

Since you are in Inspect section, then i would not bother to help you with a fixture - i don't have such knowledge to have proper scans.

But for alignment. That comes mostly from a drawing and/or real shape of that part.

If you want to have fine alignment, then use Geometric instead of ISO/ASME - this way you should be able to use side plane and bottom plane.
Also you could use those 5 holes as RPS. But i often go with local bestfit.

Thank you for pointing out my mistake. I meant to post this in Calypso. 

Is there a way for me to delete this?

 Use the CAD file to create a reference point system (RPS) alignment. This is a common alignment system used in the auto industry for things like body panels that lack standard geometries. There are threads on here about RPS alignments in Calypso. I haven't used RPS alignments all that much in Calypso, but I do remember that looping the RPS alignment at least 3X is important. Hopefully someone with more RPS alignment experience chimes in. Best of luck sir.

Thanks for the suggestion. I have never heard of that type of alignment, so I will look into that!
