Stub-backed CPACS Behavior

The current package uses deterministic stand-ins from tigl_mcp.cpacs and tigl_mcp.cpacs_stubs instead of requiring full TiXI/TiGL installations.

Why this exists

• Local development stays lightweight.

• CI remains deterministic.

• Tests can validate payload shapes and workflow contracts without native geometry dependencies.

What is intentionally simplified

• Bounding boxes are derived from component index, not real geometry.

• Sampling and intersections are synthetic but deterministic.

• Mesh and CAD exports are format-like payloads designed for stable testing.

Utility models and parsing helpers for CPACS content.

This module offers lightweight stand-ins for TiXI/TiGL objects. The goal is to provide predictable behavior in test environments while preserving the shape of the real APIs. Geometry calculations are intentionally simplified; the focus is on producing deterministic, well-structured JSON for the MCP tools.

class tigl_mcp.cpacs.BoundingBox(xmin, xmax, ymin, ymax, zmin, zmax)

Axis-aligned bounding box.

classmethod combine(boxes)

Combine multiple bounding boxes into a single envelope.

classmethod from_index(index)

Create a simple bounding box derived from an index.

class tigl_mcp.cpacs.CPACSConfiguration(wings, fuselages, rotors, engines)

Parsed CPACS configuration used by the MCP tools.

all_components()

Return all components in a single list.

bounding_box()

Envelope covering all components.

find_component(uid)

Locate a component by UID (exact match first, then case-insensitive).

class tigl_mcp.cpacs.ComponentDefinition(uid, name, index, type_name, symmetry, parameters, bounding_box)

Description of a CPACS component.

class tigl_mcp.cpacs.TiglConfiguration(cpacs_configuration, closed=False)

Lightweight TiGL configuration stub.

close()

Mark the configuration as closed.

getEngineCount()

Return the number of engines in the configuration.

getFuselageCount()

Return the number of fuselages in the configuration.

getRotorCount()

Return the number of rotors in the configuration.

getWingCount()

Return the number of wings in the configuration.

class tigl_mcp.cpacs.TixiDocument(xml_content, file_name=None, closed=False)

Lightweight TiXI document stub.

close()

Mark the document as closed.

tigl_mcp.cpacs.build_handles(xml_content, file_name)

Create TiXI/TiGL stand-ins from XML content.

tigl_mcp.cpacs.extract_metadata(xml_content, file_name)

Extract common header metadata from CPACS content.

tigl_mcp.cpacs.parse_cpacs(xml_content)

Parse CPACS XML content into a configuration representation.
