how to export model coordinates?

Hello,

I am running the example spiralInductor.

Is there a way to export the geometry for fabrication?

Thank you

Hey Naftali,

I understand that you want to export the model geometrically. While there is not a straightforward approach, you can refer to the “mesh” function to try and generate a 3 dimensional surface:

https://www.mathworks.com/help/releases/R2023b/matlab/ref/mesh.html

Once you are able to generate a suitable mesh,you can install the “stlwrite” function from the Add On Manager:

You can refer to the below MATLAB Answer as a guide to install Add Ons:

Hi Naftali,

To export the geometry of a spiral inductor from MATLAB for fabrication:

Ensure the spiral inductor object is created.

Use the "exportGeometry" function to export the geometry. For example, to export as an STL file:

 inductor = spiralInductor('NumTurns', 5, 'InnerDiameter', 0.001, 'OuterDiameter', 0.005);
   mesh = generateMesh(inductor);
   exportGeometry(inductor, 'spiralInductor.stl');

Choose File Format:

- STL: For 3D printing.

- DXF: For 2D cutting.

- GDSII: For semiconductor fabrication.

Check the exported file using a CAD viewer.

Hope this helps.

Great, This is what I was looking for.

Thank you

I tried your suggestion and did not work.

Got this messgae

No results for exportGeometry in MathWorks documentation.

Did you mean: importgeometry (98 results in MathWorks documentation).

is this a MATLAB version issue?
