DEPTH NOTCH ON A CYLINDER
DEPTH NOTCH ON A CYLINDER
(OP)
I am dipping my toe into a big pond I know, but I am trying to create some SOLIDWORKS CAD models with no training at all except for the tutorial offered with SOLIDWORKS 2003. Can someone explain to me the basics of putting a rectangular depth notch onto an extruded cylinder? This silly monkey can not figure it out. I appreciate any help you guys/gals can offer me.

If you need the bottom surface of the hole to be concentric to the outer cylindrical surface, you'll need to offset your cut (or create an offset surface before you create your cut feature) by your depth and select your cylindrical surface as the surface your prescribing an offset for. For instance, select the option to Cut->Offset from Surface and pick your depth, the direction you need the offset to be from the surface, and the surface you're offsetting the depth of your cut from.
This sounds complicated, so you can also check all this from the help menu under offset cut or offset surface or whatever. SW has excellent help.

Theophilus is correct in his first paragraph, but I would add the following.
If your cylinder has its axis coincident with the part origin you could put your sketch on any of the standard planes that is coincident to its axis. Sketch the notch cross section and extrude cut both directions. Saves the extra planes, etc.
One asumes you would have made your original sketch for the extruded cylinder with the circle center on the origin (so it is nicely fully defined). So this should work.
As to your second paragraph, Theophilus, I'm sure you know what you are talking about, but I don't have a clue.... so I doubt that our novice will either. How can something rectangular be concentric with a cylinder?

Yes, that's a bit of a confusing way to put something.
What I meant was a rectangular cut being extruded into the cylinder from the outside--from a plane offset from the axial planes and then cut back toward the axis. The bottom surface of the rectangular cut could be made to be concentric with the cylinder's outer surface. (Not sure how you would make a truly rectangular cut of that sort in real life, but who knows?)
I've had to make radial cuts in pipe-like forms before, and those aren't made with quick straight extrusions, but with surface thickenings, etc. (where all the walls radiate from the axis of the pipe or cylinder)--a slightly different trick. Since I've had need of this sort of thing I figure STOGY could just as well have need of a curved-bottomed rectangular cut. (Not sure.)

If your cut extends to the end of the rod, simply go to the end view, open a sketch there and sketch a rectangle and dimension the inner line at the appropriate location relative to the rod center. Drag the rectangle lines outside of the rod boundary if necessary and cut to desired depth.
If the cut doesn't extend to the end of the rod, make a new plane, offset from the end face, at the cut starting point. Sketch your rectangle and cut to suit.
