Experiencing some difficulty slotting the cap screw shown. The problem is this: an additional sketch is created using a rectangle .313 * .094 centered .2815 * .047 from the center of the screwhead. The sketch gets finished the extrusion is created but does not show up. The extrusion is not visible even though a new sketch was created.
Here is the drawing with the extrusion. However, when the screw is rotated from the isometric view to a front view the extrusion is no longer visible. What needs to be corrected?
Have you had any training? Worked through any tutorials?
You have produced two disconnected surfaces and then extruded a third one through those two, producing a third surface. I think that you want a single solid, correct?
I don't have 2012 installed at home, so I can't produce a model for you. But you want to fix your first sketch first- it's not fully constrained (constrain it to the origin point), and the center line is actually two lines which are construction type. Change it to one normal (non-construction) centerline type line. With a centerline-type line, dimensions to other features are taken as diameters rather than radii.
Now your second sketch needs to be incorporated into the first one-- I don't see any benefit to making it a separate feature. When you revolve that sketch you should get a solid model rather than a surface model.
Now for the slot-- again, the profile needs to be closed, and it should cut the slot exactly as you wish.
JD Mather has a very good basic skills white paper available. I don't have the link saved at home, but a quick browse through his responses to various problems should turn up the link.
