I looked at you sample can you explain what it is to be honest I cant tell..
The tool didn't work very well anyways. I know, I tried using it myself and was quickly frustrated. In the end, unless you have way complex geometery, you're much better off drawing it from scratch in Inventor. You'll find it to be faster and resulting in a better, friendlier model.
The fact is, there's just too much different about drawing in AutoCAD versus drawing in Inventor for there to ever be an easy button.
The dimension does not make much sense as this was quickly bashed together, from the original, for demonstration purposes
Thanks guys, for your opinions. We'll have to look at each drawing and decide whether it is worth using Inventor Sketches or redrawing....I suspect the later in most cases.
