Autodesk Inventor

[#1]

I am trying to create an iFeature from some basic features but Inventor throws up the following message:

Objects that are not supported by iFeatures will be removed from the selection

I have uploaded the file. Can anybody please shed some light on this for me?

I am using Inventor 2011 and Windows Vista.

It is the last loft feature in the browser that is causing the problem.

Thanks

Thanks for the help so far. Unfortunately I have still had no luck with this, I'm now having great difficulty placing the iFeature to the extent that I have invested a whole working day trying to get this to work.....it's driving me mad!

I have switched to a revolved iFeature in an attempt to simplify things but this seems to have made the problem worse. I have attached the part file. I would like to create a revolved iFeature from the last two revolutions in the browser. I don't have a problem doing this but do not know where to include relevant work planes/axis/centre marks etc. etc. I think this is what's causing a problem when placing the iFeature. Please help!?

The attached part contains one set of revolved features, the finished part will have identical features all over its surface, this is what I am trying to achieve by using the iFeature.

Any further help will be much appreciated.

Thanks
