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!

You forgot the parts...

I attached the assembly again.

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...
