How to constain the hole 'B' with flat surface 'A'

[soorajkakkoth]

I want to transfer the rotation motion of part 'C' at a pivot point 'D' , to part 'E' which is pivoted at 'F', while the flat surface of the part 'c' is inserted in to hole 'B' of part E.Please give solution to give an assembly constrain to hole 'B'  with flat surface 'A'

Contact sets

or

create dummy surface and Tangent Constraints

or

Dynamic Simulation 3D Contact Joint.

attach your assembly here if you can't figure it out.

What version of Inventor are you using?  Can you post the assembly, at least with parts E & C, plus support pins?  What is the range of motion of C?  There are several ways you might accomplish this, but it depends on your requirements.  Contact Set may be all you need.
