Hello, \\trying to run AutoCAD from MATLAB.

Tried the code proposed here

https://www.mathworks.com/matlabcentral/answers/1921990-using-the-matlab-net-interface-to-interact-with-autocad

Unfortunately I got this error

Error using dotnetAutoCADExample

Message: Call was rejected by callee. (Exception from HRESULT: 0x80010001 (RPC_E_CALL_REJECTED))

Source: Autodesk.AutoCAD.Interop

HelpLink: None

The topic was closed so I was not able to ask questions there.

Any useas?

What I need to do is plot some objects based on numbers calculated in a loop in MATLAB

Thank you

could it be a security access issue? how would I know that? this is the full code I use

%% dotnetAutoCADExample.m
%% Locate the AutoCAD assemblies
% Change these, as needed.
rootdir = 'C:\Program Files\Autodesk\AutoCAD 2016';
Interop = 'Autodesk.AutoCAD.Interop.dll';
InteropCommon = 'Autodesk.AutoCAD.Interop.Common.dll';
%% Make the assemblies visible to MATLAB
% Return NET.Assembly objects
NET.addAssembly(fullfile(rootdir,Interop));
NET.addAssembly(fullfile(rootdir,InteropCommon));
%% Open a new instance of AutoCAD
app = Autodesk.AutoCAD.Interop.AcadApplicationClass;
app.Visible = 1;
%% Open a document 
filename = 'C:\Users\nqh1127\Documents\MATLAB\test1.dwg';
doc = app.Documents.Open(filename);
%% Add a PolyLine in the form of a rectangle and get the Exploded parts
coords=[2;0;0;4;0;0;4;4;0;0;4;0]; 
% Add the PolyLine to the Model Space
rec = doc.ModelSpace.AddPolyline(coords);
% Explode the rectangle
reckage = rec.Explode;
app.Update
app.ZoomAll
%% Create another region from an arc and a line
% Create the arc and line
arc = doc.ModelSpace.AddArc([5; 3; 0], 2, 0, 3.141592);
chord = doc.ModelSpace.AddLine(arc.EndPoint, arc.StartPoint);
% Add a region composed of different object types
% See output of:   >> superclasses(arc) and >> superclassess(arcline)
% arc and arcline have IAcadEntity as a superclass
% Create an array of type IAcadEntity
acadEntityArray = NET.createArray('Autodesk.AutoCAD.Interop.Common.IAcadEntity',2);
acadEntityArray(1) = arc;
acadEntityArray(2) = chord;
halfCircleRegion = doc.ModelSpace.AddRegion(acadEntityArray);
%% Save the changes
doc.Save

I don't know much about dotnet function, it might be possible that AutoCAD allows the access in newer versions. If you have the newer version, try with it.

Otherwise, try to start it with actxserver. You need to find out the exact name for your version though on internet. Maybe this helps.

AcadApp=actxserver('AutoCAD.Application.19.1'); % AutoCAD2014
AcadApp.Visible = true();
AcadDoc = AcadApp.ActiveDocument;
AcadModelSpace = AcadDoc.ModelSpace;
lineObj = AcadModelSpace.AddLine([0,0,0]',[1,0,0]'); % drawing a line
