I am trying to figure out how to place some holes on the surface of a cylinder that have to be machined out. Drilling holes on the outside of the part but along specific angles.
I might be approaching this the wrong way, but what I did was create lines along the locations I need and wanted to then create my holes along the surface by snapping to the line and project them on the surface at the proper angles.
I can't seem to figure out how to get the holes to lay along the surface of the cylinder.

A Picture and project is worth a thousand words so I have attached my bobcad file.
Any and all help / suggestions is appreciated.

I am not exactly sure if this is what you want. But I took your hole and Extrude cut it through the cylinder then extracted the edge of the cut.

Unfortunately I can't open the file. It is from a newer version (I am on V26 Build 1335)
It sounds like you may have done what I needed, but were you able to get the hole center to snap to where my line intereseted the cylinder? That is where I am having the most difficulty.

Not sure I unerstand.I am short on time,,,but you might want to learn using the UCS ,,,check help files and Al's video's,,,hope that helpa.

To get the holes to align with the angles correctly I rotated the part so the angle where the hole is required is at 90 degrees (Top view), I created a circle the diameter of the part at the same plane as the angle line ( 2.0 in Z) and where the two lines intersect I placed a point, then snapped the circle for the hole to the point and extruded the circle as a solid and then just did a Boolean subtract and ended up with a hole the correct diameter that was cut at right angle (90 degrees) to the circumference of the part.

Hope that isn`t too involved for you but it is probably easier than messing with the UCS(s) if you aren`t up to speed with doing that, anyway have a look at the attached file and the image, not sure that`s what you are asking for but it may be of some help to you

OIC now Rob,,,,,,UCS takes awhile to learn,,,I avoided it like plague.Decided to finally learn it one day and now I have another powerful tool to use,,,I agree,,,not for the new guys.
