So i will give a quick background, this are two stl files, one is fully deformed at bottoma and other is non deformed. I want them to overlap as to measure displacement of nodes from non deformed to deformed. I have tried to show pair them with pointcloud function byt somehow they are not aligning and sitting at a distance from each other.

Do both the stl files have same number of nodal connectivities and nodes? If so you can subtract them. If not you can make your own grid and get the respective Z values for both the stl files; now they have common (x,y) and then you can find the difference and get the displacements.

Hey, can you spoon feed this please? The stl files are generated from MRI of same person just with different base (hard/soft and one side hanging). So I will need to go with grid. Can you explain how to go with that?

Read about griddata.
