SceneRootObject instead of ObjectMesh

[VoRodin]

After recent updates, the loadSceneObject() function in Python API returns the new type for loaded step files.

How can I go back to the previous type, I was using its function extractMesh() to return meshes inside and
with recursive extraction from obj.children()?

Should I switch to other approach in latest library version?

Hello, the Python module has been updated to match the C++ API. You can now check an object for the 'ObjectMesh' type and retrieve its mesh using the mesh() method:

if obj.typeName() == 'ObjectMesh':
    mesh = obj.mesh()
    mesh.transform(obj.worldXf())
    ...

Or you could use these methods to re-create the extractMesh function:

def extractMesh(obj):
    if obj.typeName() == 'ObjectMesh':
        return obj.mesh()

if mesh := extractMesh(obj):
    mesh.transform(obj.worldXf())
    ...

Hi @oitel , sorry, I still don't understand how to proceed from here:

obj = mm.loadSceneObject(stp_file)

because obj.typeName() here is a RootObject

You can process it as a usual Object instance because RootObject is its subclass and contains the children() method for iterating.

Hi, yes I got it now👍
