You can open the pointcloud/mesh in CloudCompare and pick points there and export to dxf. You can also draw lines and export.

You can also use the orto and dsm in QGis.

Welcome!

The WebODM UI has some tools for measuring that Andreas is referring to.

But can you pick points and export in WebODM?

#6

You can get point location information, yes.

But no export. I thought I missed something.

CloudCompare is really a goldmine for pointcloud editing.

If you’re working with just ODM, you’ll need to pass the proper flags:
