How to set user coefficient in ETABS APIV22 with C#?

[670Lynn]

HI, I'm new here.
I’m currently building an automated structural-analysis workflow with the ETABS API, but I can’t find a way to programmatically set a load pattern’s User Coefficient or assign seismic loads that rely on it. After combing through the ETABS API documentation, it appears there’s no direct method exposed for specifying User Coefficient values.

Has anyone run into this limitation before? If so, how did you work around it, or what alternative approach would you recommend?

It looks like you can modify user coefficients through the interactive database table, which means in turn you can access this in the ETABs API.



Have you tried the database tablese get and set methods?

I have a few examples on github of using these methods.

TableKey = 'Section Cut Definitions'
TableVersion = 1
FieldsKeysIncluded = ['Name', 'Defined By', 'Group','Result Type', 'Result Location', 'Location X', 'Location Y', 'Location Z', 'Rotation About Z','Rotation About Y', 'Rotation About X', 'Axis Angle', 'Element Side', 'Number of Quads', 'Quad Number', 'Point Number', 'Quad X', 'Quad Y', 'Quad Z', 'GUID']
NumberRecords = len(flat_etabs_data)
        

y = SapModel.DatabaseTables.SetTableForEditingArray(TableKey,TableVersion,FieldsKeysIncluded, NumberRecords,mega_data)             
    
FillImport = True
z= SapModel.DatabaseTables.ApplyEditedTables(FillImport)
