I am looking for a 2D to 3D tool for inventor. According to some posts there is a tool at Autodesk Labs but this appears to have been discontinued.
Are there any tutorials / videos of how to achieve this goal now?
Are you trying to take your autocad data and make it 3D in Inventor?
You can simply copy and paste into your Inventor sketches.
I would immediately convert to Inventor Sketch Blocks.
I've never used sketch blocks before but from what I can see it is only good for flat extrusions. What happens if I want to extrude something which is round on both the X and Y axis?
Well I don't recommand using autocad sketches much but if you do do what JD said.
You will find more issues doing this than to just redraw with Inventor.

I don't recall ever seeing an extrusion like this.
Attach the dwg here.
In any case, I'm pretty sure that labs add-in would have only automated what I just described - copy and paste into sketch.
It was not an Easy Button that would magically produce 3D geometry.
As jim noted - most find AutoCAD stuff to be not of the best quality on import and usually just start from scratch in Inventor using the AutoCAD only for reference. If you did the AutoCAD work - and know it is good quality, then use it. Otherwise expect to find a lot of fudge.
I think it would take significantly less time to create from scratch than to use that labs tool to import.
I was thinking you were using far far more complex geometry.
See attached Inventor ipt example file.
As I suspected - one of the dimensions does not make logical sense. And the AutoCAD information is incomplete or confusing (see extrusion feature). (as jim just confirmed in his response)
