How to convert matlab plot figure into stl file ? Further I Want to use it for my uav scenario .

I created a scenario for uav trajectory testing but now i am unable to import the scenario file to my UAV scenario designer .

Here is the code for reference :

scene = uavScenario("UpdateRate", 200 , "StopTime", 2, "ReferenceLocation",[46,42,0]);

>> scene.addInertialFrame("ENU", "MAP", trvec2tform([1 0 0]));

>> scene.addMesh("Polygon",{[-100 0; 100 0; 100 100; -100 100],[-5 0]},[0.3 0.3 0.3]);

>> scene.addMesh("Cylinder",{[20 10 10],[0 30]},[0 1 0]);

>> scene.addMesh("Cylinder",{[46 42 5],[0 20]},[0 1 0],"UseLatLon" , true);

>> traj = waypointTrajectory("Waypoints", [0 -20 -5; 20 -20 -5; 20 0 -5],"TimeOfArrival",[0 1 2]);

>> uavPlat = uavPlatform("UAV",scene,"Trajectory",traj);

>> updateMesh(uavPlat,"quadrotor", {4}, [1 0 0],eul2tform([0 0 pi]));

>> addGeoFence(uavPlat,"Polygon", {[-50 0; 50 0; 50 50; -50 50],[0 100]},true,"ReferenceFrame","ENU");

>> insModel = insSensor();

>> ins = uavSensor("INS",uavPlat,insModel,"MountingLocation",[4 0 0]);

>> ax = show3D(scene);

>> axis(ax,"equal");

>> setup(scene);

>> while advance(scene)

% Update sensor readings

updateSensors(scene);

% Visualize the scenario

show3D(scene,"Parent",ax,"FastUpdate",true);

drawnow limitrate

end

>> addCustomTerrain("CustomTerrain","n39_w106_3arc_v2.dt1");

>> scenario = uavScenario("ReferenceLocation", [39.5 -105.5 0]);

>> addMesh(scenario,"terrain", {"CustomTerrain", [-200 200], [-200 200]}, [0.6 0.6 0.6]);

>> show3D(scenario);

>> buildingCenters = [-50, -50; 100 100];

>> buildingHeights = [30 100];

>> buildingBoundary = [-25 -25; -25 50; 50 50; 50 -25];

>> for idx = 1:size(buildingCenters,1)

buildingVertices = buildingBoundary+buildingCenters(idx,:);

buildingBase = min(terrainHeight(scenario,buildingVertices(:,1),buildingVertices(:,2)));

addMesh(scenario,"polygon", {buildingVertices, buildingBase+[0 buildingHeights(idx)]}, [0.3922 0.8314 0.0745]);

end

>>

show3D(scenario);

>> view([0 ,15])

>> removeCustomTerrain("CustomTerrain")

Hi Karnvir,

I understand that you want to convert mesh data to 'STL' file. To achieve this, you can download some STL file conversion tools from File Exchange:

https://www.mathworks.com/matlabcentral/fileexchange?term=STL

For example:

https://www.mathworks.com/matlabcentral/fileexchange/20922-stlwrite-write-ascii-or-binary-stl-files

https://www.mathworks.com/matlabcentral/fileexchange/36770-stlwrite-write-binary-or-ascii-stl-file

etc.

I hope this helps.

MATLAB has had STL read/write tools since R2018b

stlread

stlwrite

I don't know anything about these UAV toolbox tools, so I don't know how easy it is to get the displayed content into an acceptable form for export.
