Compare two stl files

Hi,
I have to compare two different stl files referring to a 3D CAD model and its 3D printed model. (complex interconnected porous geometry) I used the distance computations and also the plugin M3C2 (after sampled the mesh). I had also read the difference between the two methods. I would like to know if there is a way to highlight the differences between the two models plotting on screen not only one of the two mesh file with the colour scale but also one of the two mesh file with the addition of the pieces, i.e. in a gray or transparent scale, of the other mesh.
Thank you in advance foor your Job.

Well, you can use the 'Edit > SF > Filter by value' tool to segment the part with distances above a given threshold?

In which way I have to use it? After computed C2M distances i have to apply it on the compare mesh or in the reference one? Or after computed M3C2 distances ? Thank you for your Answer.

It can be used after any distance computation process (C2C, C2M, M3C2, etc.). And you should apply it to the compared entity (the one that holds the distance scalar field).
