Creating Custom Metadata attributes for entities

priyanshude521

I am working on a traceability issue, which requires me to assign custom made IDs to Parts and Components(on Hypermesh Python API Hyperworks 2025.1). Manipulating already existing attributes is possible through set_attribute_value() method but making our own custom attribute (custom IDs) throws an AttributeError 'NoneType' object has no attribute 'GetValueBasicType'. Can someone help me out with this.

Hi @priyanshude521

Adding metadata to entities can be done via dedicated APIs - for example, to add a string metadata to elements ID 3, 4, 5:

import hm
import hm.entities as ent

model = hm.Model()

model.metadatamarkstring(
collection=hm.Collection(model, ent.Element, [3,4,5]),
name="String_Val",
value="Warped elements"
)

FYI Each metadata type requires the usage of the appropriate API (metadatamarkstring, metadatamarkdouble, metadatamarkint, etc.).

Thanks,
