Add steel sections with MATLAB 1

[samcivil23]

Hi .
I am using this code to add steel sections.

%% Import new frame section property
ret = SapModel.PropFrame.ImportProp ('IPE180', steel, Sections8.pro, 'IPE180');

But this error was finished

Undefined function or variable 'steel'.
Error in new (line 189)
ret = SapModel.PropFrame.ImportProp ('IPE180', steel,
Sections8.pro, 'IPE180');

Where is the problem?

Hi
because Sap2000 doesn't cache letter. in this code u should use variable or instead of this, define steel as a variable.
i think in manual of Sap explain that u use 1 for steel material and 2 for concrete.
that's ok?
