CST Macros Code to MATLAB Code

Hlw I am wring a code in matlab where I am interfacing CST using MATLAB code.For this I have to write individual function in MATLAB from CST VBA Macros code.

This is a code for extrude in CST

Sub Main ()

'## Merged Block - define extrude: component1:solid1

StartVersionStringOverrideMode "2022.3|31.0.1|20220204"

With Extrude

.Reset

.Name "solid1"

.Component "component1"

.Material "PEC"

.Mode "Pointlist"

.Height "1"

.Twist "0.0"

.Taper "0.0"

.Origin "0.0", "0.0", "2"

.Uvector "1.0", "0.0", "0.0"

.Vvector "0.0", "1.0", "0.0"

.Point "6", "1"

.LineTo "5", "1"

.LineTo "5", "2"

.Create

End With

StopVersionStringOverrideMode

End Sub .From this I have written the following MATLAB Code for extrude function

function Cstextrude(mws, Name, component, material, Mode, Height, Twist, Taper, Origin, Uvector, Vvector, Points)

invoke(extrude, 'Reset');

invoke(extrude, 'Name', Name);

invoke(extrude, 'Component', component);

invoke(extrude, 'Material', material);

invoke(extrude, 'Mode', Mode);

invoke(extrude, 'Height', Height);

invoke(extrude, 'Twist', Twist);

invoke(extrude, 'Taper', Taper);

invoke(extrude,'Origin', num2str(Origin(1)), num2str(Origin(2)), num2str(Origin(3)));

invoke(extrude,'Uvector', num2str(Uvector(1)), num2str(Uvector(2)), num2str(Uvector(3)));

invoke(extrude,'Vvector', num2str(Vvector(1)), num2str(Vvector(2)), num2str(Vvector(3)));

for i = 1:size(Points, 1)

point = Points(i, :);

X_point = point{1};

Y_point = point{2};

invoke(extrude, 'LineTo', X_point, Y_point);

end

invoke(extrude, 'Create');

release(extrude);

end

But I am not getting exact shape from this code and I think for i = 1:size(Points, 1)

point = Points(i, :);

X_point = point{1};

Y_point = point{2};

invoke(extrude, 'LineTo', X_point, Y_point);

end this part might be not showing what

Point "6", "1"

.LineTo "5", "1"

.LineTo "5", "2" this part is doing in vba macros in cst.

Can anyone please tell me

for i = 1:size(Points, 1)

point = Points(i, :);

X_point = point{1};

Y_point = point{2};

invoke(extrude, 'LineTo', X_point, Y_point); is this part is correct?

Hi Mashrur Zawad,

As per my understanding, you are trying to write a MATLAB function from CST VBA Macro code.

In your CST VBA macro code, you define a point and then draw lines to create the shape:

.Point "6", "1" 
.LineTo "5", "1" 
.LineTo "5", "2" 

In your MATLAB function, follow the same process i.e., set the initial point using the "Point" method and draw lines using the "LineTo" method from that initial point to other points.

Refer to the following updated MATLAB function:

function Cstextrude(mws, Name, component, material, Mode, Height, Twist, Taper, Origin, Uvector, Vvector, Points)
    extrude = invoke(mws, 'Extrude');

    invoke(extrude, 'Reset');
    invoke(extrude, 'Name', Name);
    invoke(extrude, 'Component', component);
    invoke(extrude, 'Material', material);
    invoke(extrude, 'Mode', Mode);
    invoke(extrude, 'Height', Height);
    invoke(extrude, 'Twist', Twist);
    invoke(extrude, 'Taper', Taper);
    invoke(extrude, 'Origin', num2str(Origin(1)), num2str(Origin(2)), num2str(Origin(3)));
    invoke(extrude, 'Uvector', num2str(Uvector(1)), num2str(Uvector(2)), num2str(Uvector(3)));
    invoke(extrude, 'Vvector', num2str(Vvector(1)), num2str(Vvector(2)), num2str(Vvector(3)));
    
    % Set the initial point
    initialPoint = Points(1, :);
    invoke(extrude, 'Point', num2str(initialPoint(1)), num2str(initialPoint(2)));
    
    % Use LineTo for remaining points
    for i = 2:size(Points, 1)
        point = Points(i, :);
        X_point = num2str(point(1));
        Y_point = num2str(point(2));
        invoke(extrude, 'LineTo', X_point, Y_point);
    end
    
    invoke(extrude, 'Create');
    release(extrude);
end

Hope this helps!
