588-599: Add handling for 3D cases.The added code correctly handles 3D cases by defining
elements_sec,boundary_sec, andedges_sec. Ensure that the boundary and edge definitions are accurate.
628-634: Ensure degree elevation logic is necessary.The degree elevation logic ensures that all degrees match the maximum degree. Verify that this operation is necessary and does not introduce unintended side effects.
644-663: Ensure knot vector formatting is correct.The
kv_secfunction formats knot vectors for export. Verify that the formatting meets the requirements of the MFEM format.

Clarify the purpose of ncps and its calculation.
The variable ncps is initialized to 1 and then multiplied by the second element of each knot vector. A brief comment explaining its purpose would improve readability.
# Initialize ncps to 1, will be used to calculate the number of control points
ncps = 1
for kv in knot_vectors:
degrees.append(kv.pop(0))

Ensure safe evaluation of knot vectors.
Using eval can be risky as it may execute arbitrary code. Consider using ast.literal_eval for safer evaluation.
