0.5T Chain Block / Crane with animated chain links.
difficult with the inventor and amazing
I've added a PDF of an instruction set that goes over the basics for laying out a chain over a path. The issue you're having with the orientation of the part is probably caused by the Orientation setting on the rectangular pattern in the Chain Path sketch. This needs to be set to Direction 1. Other issues may come from not selecting the correct start point for the rectangular pattern, or by constraining the part to the wrong work point in the assembly. It may take a bit of trial and error before getting everything just right.
As for constraining the links to the chain path, I constrained the centre point of the link to the first work point of each pattern, I then constrained the origin planes of the links to the origin plane of the chain path sketch, to give them that interlocking look. Then I constrained the origin plane of the link to the straight line of the sketch to give it the correct orientation to the path. I'm not sure why Inventor won't let you do the same thing? Is the sketch fully visible in your assembly?
Nice model, Nick. The STEP file imported perfectly into SolidWorks 2013.
