How to set up planes to drill angled hole at bottom of another

    I'm trying to drill a small angled hole into the radius of a flat bottom hole and can't figure out how to set up the planes to do that. The angle isn't important for now, I haven't got that far, the inner dimensions still aren't fixed. I've included a jpg of what I want to do and the file as far as I've gotten. Any help would be appreciated 100.jpg

    Attached is what I think you were asking for. Look at the Equation Editor Values to see how I Named thing to make them easier to find and modify. -- Lew

    Wrong hole, it's the one 60° to that one(1/8 NPT x .355) where I sectioned the part and the reference surface is the .04 radius at the bottom of the hole but I understand where you're going. This is what I got, don't know if it could be easier but .... Thanks for getting me going in the right direction!

    Looks like we arrived at the same results but how did you place plane 10?

    That's quick and simple but now, if I have to go in and change the angle, how do I do that? How did you get the line constrained to the center line of the torus and the work plane?

    Plane tangent to a surface, learned something new! Thanks!

    Used 2D Project to sketch on edge of radius and used this sketch to constrain a concentric circle sketch. (all Sketch 7)

    The centre node of this circle is used to constrain the 3D sketch line, that will then pivot around this point and can have an angle dimension applied. This line is then used to generate a plane and the node on this plane (from the end of the line) is used as the centre for a 2D Extrude Cut.

    I've put all the steps back in this file.

    Much faster than the way I did it, obviously I need more practice in 3D!
