Is it possible to go for 2D modelling with the same data used for 1D modeling?

Use the "generateMesh" function in the Partial Differential Equation Toolbox to generate a 3D mesh.
Refer to the following example that imports a 3D model, creates a mesh, and displays the mesh.
model = createpde;importGeometry(model,'Torus.stl');mesh = generateMesh(model);[p,e,t] = meshToPet(mesh); %convert form of mesh
figure; pdemesh(mesh);figure; pdemesh(p,e,t);For more details refer to the following link:
