trying to change the labels of my selected joints in etabs, but I am getting the following error

try

% Connect to ETABS

ETABSObject = actxserver('CSI.ETABS.API.ETABSObject');

% Attempt to access the SapModel property to check if ETABS is open

SapModel = ETABSObject.SapModel;

% Prompt the user to select joints in ETABS

msgbox('Please manually select the joints in ETABS to rename.', 'Info', 'modal');

pause(5); % Allow time for user to select joints

% Get the selected joints

selectedJoints = SapModel.SelectObj.GetAllPoints;

% Check if any joints are selected

if isempty(selectedJoints)

error('No joints selected. Please select joints in ETABS before running the script.');

end

% Sort the selected joints by their current labels

[~, idx] = sort({selectedJoints.Name});

selectedJoints = selectedJoints(idx);

% Rename joints to consecutive labels (1 to 1500)

for i = 1:length(selectedJoints)

newLabel = num2str(i);

SapModel.PointObj.SetLabel(selectedJoints(i).Name, newLabel);

disp(['Joint ' selectedJoints(i).Name ' renamed to ' newLabel]);

end

I am getting this error,

Error: Undefined function 'GetAllPoints' for input arguments of type 'Interface.CSi_Application_Programming_Interface__API__v1_cSelect'.

Hi Abdirahman Yasin,

The error message you are encountering in your MATLAB script indicates that the function “GetAllPoints” is not recognized for the input argument of type “Interface.CSi_Application_Programming_Interface__API__v1_cSelect”. Here are few ways to troubleshoot the issue:

• Instead of using “GetAllPoints”, consider using the “GetSelected” method to retrieve selected objects.

% Get the selected joints
selectedJoints = SapModel.SelectObj.GetSelected;

• Ensure that you are using the correct version of the ETABS API. If you’re using an older version, consider updating to a newer one.

I hope this helps!

Best Regards,
