Hello All,
I am trying to create a simple hole with threads for a set screw on a hub. I cannot figure out how to select the tangent plane I need to create the sketch. I'm using Inventor 2013 and have attached the file below. All suggestions are welcome! Thanks.

Sketch1 is not constrained.
I recommend you read this document http://home.pct.edu/~jmather/SkillsUSA%20University.pdf
see attached file for one method.
Thanks, that worked great! Another question... After the hole/cutout has been created, should there be any problems assembling items in it? I created the hole on the hub itself and tried creating the hole in assembly. When I go to insert the set screw, it will select every hole in the hub except the one on the tangent work plane. Any advice?
Create an axis through the center of the hole (if one of the Origin axis does not already go through the centerline).
Create a workpoint at the intersection the axis and the workplane.
The hole, workpoint and workplane can be used to place fastener.
Attach your assembly here if you can't figure it out.
I still could not figure out how to do this... I have attached the file. The set screw is not the one that I plan to use but I just needed a simular one to work with. Thanks!
The assembly file specifies how the parts are put together, but it doesn't define the parts. We need the component files (.ipt), too.
Ok, got it. The set screw I got from the conent center so I just attached the hub. Sorry for the mix up!
OK, easy constraints. You already have the workplane there, so constrain the flat top of the set screw to the workplane (with an appropriate offset), then constrain the axis of the screw to the axis of the hole. Finished.
By the way, why did you extrude the hole in the hub and then thread it, instead of just making it a threaded hole feature? You have the sketch there with the hole center located, just make it a hole to the center bore of the hub. Then it will annotate correctly on your drawing.
I also looked through the rest of your model-- you haven't had any training, have you? Please read the document that JD mentioned in his post-- your sketches are not constrained, so your results are probably not what you want-- look at your four countersunk holes...
Here's another example to go with JD's. It's all constrained and easily and predictably editable. Your original hub has four countersunk holes that are a mystery since they are threaded, and they're too close to the hub. A #5 flat-head screw would run into the hub in that position. Pull the EOP up to the top and go through it feature by feature; ask if anything doesn't make sense to you.
Thanks Sam! The first solution worked perfectly. And no, I have not been trained in this or any Autodesk product. When I learned CAD, we used SolidEdge but I have been trying to self-teach some of the Autodesk products for a project that I am working on. Trying to get it done the quick and dirty way, I often forget to constrain my sketches... Thanks again.

If you do it right - you don't have to constrain your sketches - Inventor does this for you.
That is why you should worry about it now, once you learn how Inventor will do the work for you it all gets must faster.
In my experience the "quick and dirty way" always ends up being the slow and dirty way. No winning solution in that.
I am trying to create a hole on a surface that is not flat. I am unable to create a sketch or a work plane due to the curved surface. I need to place a hole on the side of the open end 1.125" up from bottom. Any help would be appreciated. I am workinng with Inventor 2013
Thanks, BB
I noticed that several of you sketches are not fully defined?
see attached for one method. (I didn't take the time to try to get hole in precise position as I don't know relative to what?
Sorry about that, I need the hole perpendicular to the surface you have it on, Ive relocated the hole into proper location, just not clear how you were able to create the work plane. Did you create WP 5 and 6 to get the axis?
Thanks
BB
I will come back tomorrow with instructions on more precise way of placing the hole.
The key is to get the perpendicular pierce point where the axis of the hole passes through the curved surface.
Hell, I need help modeling the exaust pipe seen below at the atached files, the main problem is creating the axis for the holes, normal to the multiple curved surfaces, and using some kind of patern after that
