How to get all point from .xyz or .e57 file?

Hello.

I want to create morph from .xyz or .e57 file point cloud data.

Now, I create mesh with 'File -> Interoperability -> Place Mesh from Surveyors Data...' and convert mesh to morph.

But, this method only works for .xyz file.

I placed a point cloud library object using 'File -> Interoperability -> Import Point Clouds...', but I don't know how to convert it to a mesh.

I find this. Still unable to access point cloud points?

How can I create mesh using .xyz or .e57 file?

One could use an external program called "cloudcompare" to convert e57 data.

Its free and powerful but needs some time to get into.

Point Clouds are not meshed, they are just that: Points.

If you want to get a mesh out of Point Clouds you need a third-party software, just like the mentioned Cloudcompare.

You could also try Rhino 8's new "ShrinkWrap" command.

If the xyz or e57 data is formatted correctly ArchiCAD can import it as terrain, thus convertiable as morph.
But this only works with terrain data, eg. no overhangs etc.
