... the tutorial is leaving me with open loops on the side pins when I go to extrude the sketches.
Attach your *.ipt file here.
I don't want to speak for Steve, but when I write a paper like that it is intended to be limited notes for those who attend the presentation. A suppliment to the class, not a replacement. Before teaching/learning iParts I would expect the user to have significant prior experience and be able to create any required sketch. This would be an intermediate to advanced level class.
Attach your part and someone will show you how to fix it.
I only sat down and really tried to use inventor for the second time today ....
Create your new attempt and attach it here tomorrow, but I recommed you go through these before trying to do too much and developing bad (for Inventor) modeling habits.
So the tutorial you linked to is a bit out of date in terms of the tools that were available when it was written. Attached is an example file that demonstrates a very simple dovetail joint made using multibody solids in a single part, and using the Combine tool to subtract one solid from the other. Use the End of Part marker to step through the part to see how each feature was created. Note that once the joints are create, you could write each solid out as an individual parts useing the Make Components tool. You could also, use the Thicken/Offset tool to loosen up the joints to add some fit tolerance.
Also, have a look at this link and I think you'll see some familiar issues that you've encountered already:
I hope this helps.
Best of luck to you in all of your Inventor pursuits,

That is so helpful, THANKS!
I've put the file I was working on, please take a look and let me know why those sketches wouldn't extrude properly.
I probably would work it out by following some of the links reccomended to me, so I will try those soon.
I just get the feeling it might be something in the settings because they are pretty much stock settings.
I'd like to be able to show that all dimensions are, what is the setting for that because when I push F8 like I read somewhere it doesn't show anything.
Sketch1 is missing a dimension and not placed at the Origin Center Point (most basic of all Inventor techniques - master this).
(and it is easy - as Inventor will do it for you - simply click on the projected origin as your first point when creating the rectangle)
Workplane1 is not needed because the step above was not done correctly - more extra work that Inventor would do for you.
Sketch2 is missing a dimension. The width dimension is not needed as it has already been defined. The 90° dimension is not needed as it has already been defined. Actually - all of Sketch2 is not needed (even though it is used in the original tutorial - I'll explain later.
Sketch3 and 4 have no apparent purpose and can be deleted.
I will explain step-by-step corrections.
just a follow up, on that file you sent.
I made a set of user defined parameters,length,width,thick,Tailwidth,Tailslope and pitch,
then I attmepted to adapt the model you sent to those parameters so I could change a few measurements but keep usable plans for the joints,
Thats my main focus here, and you model worked mostly..
but now I want to know why a few things didn't go so well and I have attatched the file after my attempt so you can see what I mean.
1:Why doesn't Extrusion3 have a dimension I can change for it's Y axis? (I've named it "width" in extrusion1 and could change that one)
2:Extrusion1 has a dimension (d4) that I just cant work out how it works, it makes your model a little bit different to the one in the tutorial, doesn't it?
