OpsSection is the outer boundary produced by a single producer (raster assembler, material test grid, vector cut). StateBlock nests inside OpsSection and delimits sub-regions where device parameters change.

Consuming the new APIs

Iterating sections by type and mode

sections = ops.sections()

raster_sections = ops.sections_by_type(SectionType.RASTER_FILL)
variable_power = ops.sections_by_mode(RasterMode.VARIABLE_POWER)

for sec in sections:
    print(sec.section_type, sec.raster_mode)

Extracting section content

section = ops.sections()[0]
content = ops.section_content(section)
content = section.content(ops)  # convenience

Reading section params

st, uid, mode = ops.section_params(idx)
# mode is None for VectorOutline, RasterMode variant for RasterFill

State blocks within a section

section = ops.sections()[0]

blocks = section.state_blocks(ops)
for b in blocks:
    print(b.name)
    print(b.marker_indices)
    print(b.content_indices)
    block_ops = b.content(ops)

labels = section.state_blocks_by_name(ops, "labels")     # exact match
cells = section.state_blocks_by_name(ops, "cell-*")      # prefix match

Flat iteration

all_blocks = ops.state_blocks()  # across all sections

Assembler output with markers

The raster and material-test-grid assemblers now emit section and state block markers:

result = raster(part, mode="power_modulated")
sections = result.ops.sections()
# Each section has raster_mode set appropriately

result = generate_material_test_grid(params, size_mm)
sections = result.ops.sections()
labels = sections[0].state_blocks_by_name(ops, "labels")
cells = sections[0].state_blocks_by_name(ops, "cell-*")
