Hi,

To test the changes made to a scenario exported from the Driving Scenario Designer app in MATLAB, follow these steps:

Export the Scenario:

• Export your created scenario to a MATLAB function using the Driving Scenario Designer app.

Modify the MATLAB Function:

• Open the exported MATLAB function in MATLAB.

Save the Scenario Data:

• At the end of the function, add the following line to save the scenario data to the workspace:

save("data.mat") % It will save the data to workspace

Launch the drivingScenarioDesigne app:

• Now Run the below command to open the scenario in drivingScenarioDesigner app

drivingScenarioDesigner(data.scenario) % Here we are trying to load the scenario into drivingScenario app
% please check the scenario object name and modify it accordingly

• Now you can visualize the changed scenario in "drivingScenarioDesinger" application.

Please refer the below code for reference:

function scenario = createDrivingScenario()
% createDrivingScenario Returns the drivingScenario defined in the Designer

% Generated by MATLAB(R) 24.2 (R2024b) and Automated Driving Toolbox 24.2 (R2024b).

% Construct a drivingScenario object.
scenario = drivingScenario;

% Add all road segments
roadCenters = [38.2 9.9 0;
    37.3 -1.2 0;
    30.5 -7.9 0;
    27.6 -13.5 0;
    29.6 0.1 0];
road(scenario, roadCenters, 'Name', 'Road1'); % Chnaged the Road name to Road1
save("data.mat")

Hope it helps!
