If I understand correctly...
- Center your umbrella above the flares
- Create a sketch on the bottom of the umbrella and project this sketch to the flares making a split line.
- Hide the sketch
- [Coincident] Mate the umbrella OD to one of the split lines.
Something like that.
That's the gist, no time at the moment for a model, but that'd be my plan of attack.
Try this (see attached SW 2017 assembly and video).
Technically, you could add in some curve to this line here to get a more realistic "approach". But the idea is sound.
So here is what I did:
1) edited the revolve or your part2.7 to put the sketch from the revolve in the middle of the part rather than at one end.
2) Used the arcs from the sketch that made the revolve in part 2.7 and the arc from the revolve in your base part and made them coincident (since they were the same radius, this was convenient). If they weren't the same radius, this would have been a little trickier.
3) Added a limit angle relationship between the bottom line from the sketch in part2.7 to the top of the sketch line in your base plate. I made it range from .001 degrees (you get problems of it reversing sometimes if you let it hit 0) and 45 degrees. (this angel can be tweaked....but 45 degrees looked good to stop at interfering with the slope on the outside of your base plate.
4) edited your part2.7 and added a sketch to the side of the part (which is where the dome will make contact) and converted entities on the edge, then added a 50mm line to the top (line 3). You could have made this some sort of curves line to better simulate an approach....but I ran out of time. (I added a 2nd one on the other side, but it turned out it wasn't needed at all).
5) Then exited the sketch and created a 3D sketch and used fit spline to fit to the sketch I just created.
6) added another dummy part that is just a point in space. (part3.4)
7) Mated the origin of the dummy part to the fit spline, then mate the origin of the dummy part to the edge of the dome. For this to work, I also fixed the base plate in space and then mated one of the planes on the dome to be parallel to the main planes (so that it wouldn't spin).
Hide all the sketches and Done.
Edit: Added a 2nd video....shows it better,

LOL....oh....he said the central post of the umbrella I missed that.....that is what I get for reading too fast. LOL
Well, the same concept should still hold.
Dan,.. oh.. well, I thought the same when I first saw it.. but your's looked like it was... anyhow, it's a similar idea and you also changed the rotate to be mid..
Wow guys you are awesome, Dan's solutions is working perfectly. I would have never though of it by myself, shows i still have a lot to learn.
Thanks all for the quick responses!
