Get coordinates from entities

[JorgeFernandes-Git]

Hi @mozman

I'm using this parser and I would be glad if you can help me.

I have this code so far:

from steputils import p21

# Read the STEP file
file_path = r'step.STP'
stepfile = p21.readfile(file_path)

entities_to_get = []
for entity in stepfile.data:
    for instance in entity.instances:
        instance_params = stepfile.get(instance)
        if hasattr(instance_params, 'entity') and hasattr(instance_params.entity, 'name'):
            if instance_params.entity.name == 'TESSELLATED_SHELL':
                for param in instance_params.entity.params:
                    for i in param:
                        if i.startswith('#'):
                            entities_to_get.append(i)

print(f'entities_to_get: {entities_to_get}')

Which print:

entities_to_get: ['#27', '#28', '#29']

Now, with these entities, how can I get the respective coordinates?
Maybe with those entities, I have to use a library like pythonOCC?

Thanks in advance.
