how to resize digital model to its actual dimensions?

Hello. I'm doing a photogrammetry project. I would like to know if it is possible to perform the following tasks in meshmixer.

 

1) I need to resize the model that was reconstructed by photogrammetry (model A: plaster model + coin) to its real dimensions, using another reference model (model B: coin) that was obtained by scanning. Is it possible to align and resize the coin present in model A with the coin in its real dimensions (model B), and at the same time that this happens the rest of model A (plaster model) is also resized to its real dimensions?

 

After obtaining model A with its real dimensions, I will cut it out and leave only the plaster model present to compare it with another plaster model obtained by scanning (model C).

 

2) How do I align these two plaster models (model A and model C) and select in these models only their regions in common (intersection), to export them in two STL for mesh comparison later in cloudcompare?model A.pngmodel B.pngmodel C.png

1) https://help.autodesk.com/view/MSHMXR/2019/ENU/?guid=GUID-264CA7DD-C08F-4C1C-BDD2-E7AE193F513C

Analysis > Units/Dimension > Click and drag to set a reference line along your coin > Set Target Length (to your real world measured value)

This will scale everything based on your coin.

 

2) Set one model as a target > Selcet All on the other model > Align to target > Boolean Intersection
