Class Attributes
CreepShrinkage.mats -> List of all creep and shrinkage instances.
Methods
json
Returns a JSON representation of all Creep and Shrinkage properties defined in python.
print(CreepShrinkage.json())
# Output:
# {'Assign': {1: {'NAME': 'CS_M25', 'CODE': 'INDIA_IRC_112_2011', ...}}}
create
Sends creep and shrinkage data to Civil NX using a PUT request.
CreepShrinkage.create()
get
Fetches creep and shrinkage data from Civil NX and returns the JSON representation.
print(CreepShrinkage.get())
sync
Retrieves Creep and Shrinkage data from Civil NX and rebuilds the internal list.
CreepShrinkage.sync()
delete
Deletes all creep and shrinkage data from both Python and Civil NX.
CreepShrinkage.delete()
