Changing ipt files without the Autodesk

I downloaded a 3d model and it only came in ipt, iam, and ipj files. Is there anyway I could get these to be formatted in blender? I do not want to buy any converter software because this should hopefully be a one shot thing.
The quickest someone can answer this the better. I am on a time crunch right now

Im not able to convert it, but someone on the site should be able to help you out shortly.

Another option is to use the Workbench, uploading the model and then downloading it in whichever format was desired.
See if this link helps:

I'm not familiar with Blender, but let's hope it can import OBJ files.
Let us know if these work.
