Problem with LISP program inserting custom tapped holes onto surfaces

Hey all,

 

 

I am having some trouble with a program that generates different tapped holes.  When I try to place them on a part in 3D AutoCAD it only works occasionally.  I believe that it has something to do with the UCS.  I'd ideally have the ability to select the face and then drop the tap into the model but have not figured this out yet.  I have searched through many articles and there hasn’t been a solution to fix it yet.

I have attached the code.   If you have any suggestions please let me know.

 

Thanks!
