I have a geometry stored in an .stl file. I want to use it with importGeometry and add basic shapes to it in matlab later. How can I make it?

Import STL Geometry:

Use "importGeometry('your_stl_file.stl')" for a standalone object. (https://www.mathworks.com/help/pde/ug/pde.pdemodel.importgeometry.html)
Include in a PDE model with:

model = createpde; 
gm = importGeometry(model, 'your_stl_file.stl');.

Add Basic Shapes:

Use functions like "rectangle3", "box", "cylinder", etc. to create shapes. (https://www.mathworks.com/help/pde/geometry-and-mesh.html)
Combine shapes using "unite", "intersect", or "setdiff. (https://www.mathworks.com/help/antenna/ref/antenna.circle.add.html)

Visualize:

Use "pdegplot(combined_geom)" (requires Partial Differential Equation Toolbox). (https://www.mathworks.com/help/pde/ug/pdeplot.html)
