Hi all,

I'm looking into what Up To Surface means to different people when it comes to drilled/machined holes.  I've attached a model to this post where I have a twist drill (red) and an end mill (blue) and I was hoping some of you could help me out by taking the model and positioning the drill and mill bodies where you think they should stop when using Up To Surface if the yellow surface was selected.  You can use I3D to drag the bodies up and down or get crazy and edit the revolve sketches to constrain it how you wish.  If you could also provide some explanation as to why you think it should be where you placed, that would help greatly.

The image below shows the setup and how to drag the bodies using I3D.  The model was made in 2015.

Thanks for your help.

Jody
