Ok, so my initial review said that these files did not work as I was trying to use this model to teach hydraulics without having to lift a large cylinder to demonstrate the construction. I was wrong. This model worked perfect in Shapr3d on my iPad and works perfectly with the coloring tool in shapr as well as the AR function. This model is a life saver!!! I did struggle with which file to import as I was unfamiliar with solid works, but it was the 2355024_HC-25_63x45x250.sldasm after i downloaded them all and got them saved onto my iCloud.
