Help mating two parts together

houtan_movafagh

Hi, I am a novice when it comes to CAD but have made a multiple parts over the last year and am getting better.  Having said that, I am stuck and would be appreciate if you could help me out.

I would like to mate this PCV nipple to my short air intake.  I have the two parts made, and in the assembly, I have the nipple offset 30 degrees, but I cannot figure out how to mate the two pieces together.  The location of the mating I have marked with the hole on the intake.  Can someone please help?

Something like this:

I assumed you wanted the the elbow mated to the location you had in the part studio? I created an explicit mate connector in the part studio to use as a reference, useful for any "non-obvious" mating scenario.

Even though in this case you can also just mate directly to the hole in the air intake with offsets:

Eric, thanks for taking the time to look at my file.

so this gets me closer, but it still doesn't seem to be one item.  When I look at the elbow, it is not one piece with the larger pipe. For example if i were to extrude something and "add" it to another item.  Is this possible with the way I have tried to create this or do I need to go a different direction?

I think you are saying you want them in the same part studio (i.e. as one solid piece)? Your post title mentions "mating" so I assumed you were talking about assembly mates...

In that case you probably want to use the "derive" feature to insert the elbow into the intake part studio and then use a transform (using the "by mate connector" option is probably the easiest), then you just have to figure out how you want to make the "connection" between the two. Here's one way of doing it using an extrude with the merge scope set appropriately:

One alternative would have been to just model the elbow in part studio1 (unless you are going to "re-use" that elbow geometry in multiple places).
