- trimesh.path.exchange.dxf.bulge_to_arcs(lines, bulge, bulge_idx, is_closed=False, metadata=None)
Polylines can have “vertex bulge,” which means the polyline has an arc tangent to segments, rather than meeting at a vertex.
From Autodesk reference: The bulge is the tangent of one fourth the included angle for an arc segment, made negative if the arc goes clockwise from the start point to the endpoint. A bulge of 0 indicates a straight segment, and a bulge of 1 is a semicircle.
lines ((n, 2) float) – Polyline vertices in order
bulge ((m,) float) – Vertex bulge value
bulge_idx ((m,) float) – Which index of lines is bulge associated with
is_closed (bool) – Is segment closed
metadata (None, or dict) – Entity metadata to add
vertices ((a, 2) float) – New vertices for poly-arc
entities ((b,) entities.Entity) – New entities, either line or arc
- trimesh.path.exchange.dxf.convert_entities(blob, blob_raw=None, blocks=None, return_name=False)
Convert a chunk of entities into trimesh entities.
blob ((n, 2) str) – Blob of entities uppercased
blob_raw ((n, 2) str) – Blob of entities not uppercased
blocks (None or dict) – Blocks referenced by INSERT entities
return_name (bool) – If True return the first ‘2’ value
- trimesh.path.exchange.dxf.export_dxf(path, only_layers=None)
Export a 2D path object to a DXF file.
path (trimesh.path.path.Path2D) – Input geometry to export
only_layers (None or set) – If passed only export the layers specified
export – Path formatted as a DXF file
- Return type
- trimesh.path.exchange.dxf.get_key(blob, field, code)
Given a loaded (n, 2) blob and a field name get a value by code.
- trimesh.path.exchange.dxf.load_dxf(file_obj, **kwargs)
Load a DXF file to a dictionary containing vertices and entities.
file_obj (file or file- like object (has object.read method)) –
- Return type
dict, keys are entities, vertices and metadata
