i like to place a fillet radius of .125 at the bottom of the triangular cut to simulate a ball end mill. Mr. Inventor2014 says it is too complicated to do.
how to get around? thanks.

Solved! by dho. See the answer in context.
first, i shall thank everyone who tried to help me.
got hints from all the iptS, i moved extrusion8 after triangular extrusion9 (cut). inventor processed without an issue.
also i got response from INV sales/support (43-1065-01-support.ipt). here is his approach. but seems it did not represent truly the lower left ball end mill cut per 2D drawing.
"because you created the profile first in the pocket Extrusion with 0.125 R corners. When INV tried to blend these corners it was mathematically unable (remember 0.125 may not exactly equal 0.125 - 0.125000001 <> 0.12499999. The larger radius worked because it would skip over the corners where it was unable. the correct approach is to create the pocket with sharp corners and then fillet edges including the verticals. See attached."
the actual part does seem missing the ball end mill "turning" at the lower left corner which most models here omitted.
here is my try (43-1065-01-B.ipt), no deviation taken from 2D drawing even it had "logical" error which caused all the "fuss".
thanks again to all.
I can do it (in Inventor) but first thing I noticed is that none of your sketches are constrained.
I didn't bother to go any further.
clearly a PICNIC problem
You're getting some rough feedback based on how you presented your question. But you're also getting some good advice in that you should always create sketches to be fully constrained. Often if we do not properly constrain and dimension a sketch, non-tangent points in the sketch will cause placed feature, such as fillets, to fail.
I would encourage you to spend some time tidying up your model and if you still think you've found a limitation, resubmit it, and I'm sure someone will offer some help.
I hope this helps.
Best of luck to you in all of your Inventor pursuits,

I think I would model significantly differently.
Does this part already exist in physical form?
If so, do you have a picture of actual part?
I don't think I would model the part like this in SolidWorks or in Inventor.
