Help need with Hole in Cylinder

Hi

This is my first post. I am a total beginner to Inventor.I need to put holes in the side of a cylinder. I have watched a few video tutorials but they have no voice over and they go so fast I just can't keep up. I want to understand what I am doing and why rather than just following it blindly. Anyone know of a good video on this that I could look at. Alternatively a written tutorial would be fine. I'm using Inventor 2012

Thanks in advance

If you are looking for a book, I did a blog post about some good ones on my blog. http://inventortopix.blogspot.com

Here is one called Mastering Autodesk Inventor 2012, http://inventortopix.blogspot.com/2011/07/mastering-autodesk-inventor-2012-and.html

Here also is one for about six other books, http://inventortopix.blogspot.com/2011/08/autodesk-inventor-2012-books.html

Hope this helps a little.

I'll have a look at these. Thanks for getting back

If you can't figure it out - attach your file here and someone will walk you step-by-step through the process.

Here's the file. Its simply a narrow tapered cylinder through which I need to drill 8 holes through the sides and in about half way. Various holes will be drilled through at 90 degrees to each other and the ability to relocate them slightly along the length of the cylinder would be great. Any help would be appreciated.

I don't see where you have made any attempt at all to create the holes?

You might check out the examples in this document while I try to guestimate what you really want and work up an example.

You might be interested in the curve driven pattern information.

Revolve rectangle sketch to create hole and pattern?

Create workplane tangent to cone sketch hole centerpoint, add hole and pattern?

Any specs on the location size and depth of these holes?

Threaded?

Standard 118° drill point, or flat bottom?
