Angled Holes - New to OnShape
I need some direction on how to go about making an angled hole.
Assume you have a cube 2x2. I want a 1/2" hole diagonally from the left,rear,top corner diagonally through the cube exiting the right, front, bottom. I'm stumped (or stupid). Here is a quick drawing from TinkerCAD (sorry, I know it's cheesy! to illustrate what I mean.

The answer to this is a bit convoluted.
With a some help from @konstantin_shiriazdanov, here is my take on things.
For the hole function to work we need a sketch point normal to the direction of the hole.
For a sketch point we need a planar surface (usually an existing plane or the flat side of a part, but that's no good here)
So we need a new plane.
Now I didn't want us to have to do any math(s) (to say rotate a plane by an angle) because if we change the cube later into a cuboid it'll fall over.
So in this example we have:-
(a) 3D fit spline, to pick up the ends of the hole and determine the normal direction.
(b) A "Point Normal" Plane created on the end of the spline
(c) A sketch on the new plane with the vertex of the cube projected onto it.
(d) The hole function used to make the hole.

The 2nd example shows the same method used between a couple of points on the faces of the part instead of the corners.
It's usually at this point that @philip_thomas jumps in and says you can do that in 2 steps not 10, but at least it's a start!

Any fewer steps would involve a custom feature

I know this is an old post, but just to give another idea:
you can also use a plane, sketch out the profile and use revolved subtractive. at least that's what i usually do in this cases.
I used create 3 point plane, sketched the hole and revolved.
