Mesh¶
The MESH entity (DXF Reference) is a 3D mesh similar to the Polyface
entity.
All vertices in WCS as (x, y, z) tuples
Changed in version 0.8.9: Mesh
stores vertices, edges, faces and creases as packed data.

 dxf.version¶
 dxf.blend_crease¶
0

 dxf.subdivision_levels¶
0

.
 vertices¶
Vertices as list like

. (read/write)
 creases¶
Creases as
array.array

 edit_data() Iterator[ezdxf.entities.mesh.MeshData] ¶
Context manager various mesh data, returns
MeshData
.Despite that vertices, edge and faces since ezdxf v0.8.9 are accessible as packed data types, the usage of
MeshData
by context manageredit_data()
is still recommended.
MeshData¶
 class ezdxf.entities.MeshData¶
 vertices¶
A standard Python list with (x, y, z) tuples (read/write)
 faces¶
A standard Python list with (v1, v2, v3,…) tuples (read/write)
Each face consist of a list of vertex indices (= index in
vertices
).
 edges¶
A standard Python list with (v1, v2) tuples (read/write)
Each edge consist of exact two vertex indices (= index in
vertices
).
 edge_crease_values¶
A standard Python list of float values, one value for each edge. (read/write)
 add_face(vertices: Iterable[Sequence[float]]) Sequence[int] ¶
Add a face by coordinates, vertices is a list of
(x, y, z)
tuples.
 add_edge(vertices: Sequence[Sequence[float]]) Sequence[int] ¶
Add an edge by coordinates, vertices is a list of two
(x, y, z)
tuples.
 optimize(precision: int = 6)¶
Try to reduce vertex count by merging near vertices. precision defines the decimal places for coordinate be equal to merge two vertices.
