sketch on angle
(OP)
i have a question i have a 6 inch dia circle .250 thick, i need to put a .125 in hole on the top of the circle at a 20 degree angle to put a hole thru how is this done in solidworks, any help would be appreciated

RE: sketch on angle
Like Chris said, use the axis to drive the plane at your desired angle. I'm assuming you want the hole centered on the thickness .250". If so then the base feature should be thickened (mid-plane) about a plane. Then that plane should be used to create the axis which will be tied to the outter edge of the circle. Then create a plane Normal to curve.

RE: sketch on angle
What I do is create a construction line in the initial sketch of the 6 inch diameter circle at the desired 20 degree angle. When I create the .125 hole, I first select the cylinder face then start HoleWizard. After selecting the hole size and clicking next, a point is automatically located on the cylinder face. I use relations to make this point horizontal (or depending on the orientation, vertical or along-Z) to the end point of the 20 degree line (I resisted Heckler’s suggestion of extruding the circle using mid-plane because then all I would have had to do was make the point coincident with the end point of the conctruction line. Besides that, design intent will not always let you extrude this way.) I then dimensioned the point .125 from the end of the cylinder by select the end face and the point. Finally, I clicked finish to create the hole and then re-hid the circle sketch.
To make it easier to see what I did, you can download my example file from http://www.yourfilelink.com/get.php?fid=9712

Yes, if the hole is off center then you would have to use ctopher's solution.

I prefer creating a recess first & then placing the hole on the flat surface. It makes it easier for starting the tap when a tapped hole is required. Also the recess can be cut in both directions so that no lip is created in the hole.

Does the machine shop then manufacture the part with the recess?

RE: sketch on angle
If you select a flat face, hole wizard will generate a 2D sketch which can be used to position the hole
If you select a cylindrical face, or don't select a face at all, a 3D sketch is generated which can be used to position the hole. In general 2D sketches are much easier to control, so where possible a face should be selected before use.
Only found that out recently when reading SolidWorks for Dummies - quite a useful book even though I have used SolidWorks since 1998.
