Moving/rotating imported models

[jurekos]

Hi,
I didn't know there was such a powerful 3d viewer - the number of formats read amazes me. Great job, thank you for your work!. Is it possible to add a function that would allow you to perform simple operations to determine the mutual position of models? I import a model from a 3D scan (.glb) and a separate one in dxf - I need to adjust the zero point location and axis rotations in them. I do this separately in the dxf file, but maybe such a function could be introduced to Mayo?

Hello and thanks for your kind words about Mayo!
You would like a function that would automatically adjust position and orientation of the 3D mesh(scan) to match another model(3D object in dxf file).
How the model geometry is defined in the DXF file? Is it also a mesh?

Hi, thanks for Your response.
If automatic alignment works, that would be great, but manual alignment would be sufficient—just rotation and orthogonal translation. I have the DXF with meshes and gltf from lidar scanning. I have IFC as the source 9for dxf), but that is less important.
I can send sample files illustrating the problem.

OK you need a 3D tool in Mayo to move and rotate a part.
OpenCascade provides AIS_Manipulator class, which looks like this:

Yes, it seems to be a best/simplest solution!
This is example with merged lidar scan and dxf model:
