Material
The module provides functionality to create, manage, and synchronize materials in the model.
Note.
All the codes below assumes the initial import and MAPI Key definition.

Material
Constructor
Material(data, id=0)
Creates a material with specified data and optional ID.
Parameters
data: Material data dictionary containing material propertiesid (default=0): Manual ID assignment (auto-assigned if 0 or ID already exists)
Class Attributes
Material.mats -> List of all material instances.
Material.ids -> List of all material IDs.
# Example material data
mat1 = Material.CONC("M30 Grade","IS(RC)","M30",1)
mat2 = Material.STEEL("S450 Steel", "EN05(S)", "S450", 2)
mat3 = Material.USER("Timber", E=12000, pois=0.4, den=6, mass=6, therm=5e-6, id=3)
Material.create()
Methods
json
Returns a JSON representation of all Materials defined in python.
print(Material.json())
# Output:
# {'Assign': {1: {'TYPE': 'CONC', 'NAME': 'C30', 'DAMP_RAT': 0.05, ...}}}
create
Sends the current material list to Civil NX using a PUT request.
Material.create()
get
Fetches materials from Civil NX and returns the JSON representation.
print(Material.get())
sync
Retrieves Material data from Civil NX and rebuilds the internal material list.
Material.sync()
delete
Deletes all material data from both Python and Civil NX.
Material.delete()
