Re-Align object orientation

[Marvin_Martian]

When using 3D scanners they scan at which the orientation of the object is, is it possible to get the object re-oriented at a 0,0,0 in X,Y,Z in cloud compare, this is helpful when reverse engineering, mirroring in CAD programs etc and would this tool be the level tool ?

The issue I have with the level tool is, I understand you have to choose a center point, then an X axis followed by the Y with the X axis typically aligned with the center point. I have problems with getting it aligned based on the world axis that included the bounding box to be perfectly aligned so that I can bring into a CAD program, for example. And have it aligned for tools such as symmetry etc.

I have attached a screen shot to show.
This is the object when first loaded into Cloud compare, it's orientation is not aligned.

This is a crude attempt at getting it to align.

Hum, indeed, the 'Level' tool is not meant to perform such precise alignment (it's mostly aimed at creating a rough coordinate system, focusing on making the 3 points horizontal).

Maybe you would get better results with the 'Align' tool (point pair picking) if you are able to pick 3 or 4 known points in the cloud accurately.

Doesn't align, align two point clouds ?

How would I use to to make the mesh aligned and oriented ?

You can use it on a single entity with known points (for which you input the coordinates manually).
