Typedef Documentation

typedef struct dxf_polyline_struct DxfPolyline

Definition of a DXF polyline entity.

A polyface mesh is represented in DXF as a variant of a Polyline entity.
The Polyline header is identified as introducing a polyface mesh by the presence of the 64 bit in the Polyline flags (70) group.
The 71 group specifies the number of vertices in the mesh, and the 72 group, the number of faces.
While these counts are correct for all meshes created with the PFACE command, applications are not required to place correct values in these fields, and AutoCAD actually never relies upon their accuracy.

Following the Polyline header is a sequence of Vertex entities that specify the vertex coordinates and faces that compose the mesh.
Vertices such as these are described in the following subsection on Vertex.

Applications might want to represent polygons with an arbitrarily large number of sides in polyface meshes.
However, the AutoCAD entity structure imposes a limit on the number of vertices that a given face entity can specify.
You can represent more complex polygons by decomposing them into triangular wedges.
Their edges should be made invisible to prevent visible artifacts of this subdivision from being drawn.
The PFACE command performs this subdivision automatically, but when applications generate polyface meshes directly, the applications must do this themselves.

The number of vertices per face is the key parameter in this subdivision process.
The PFACEVMAX system variable provides an application with the number of vertices per face entity.
This value is read-only, and is set to 4.

Polyface meshes created with the PFACE command are always generated with all the vertex coordinate entities first, followed by the face definition entities.
The code within AutoCAD that processes polyface meshes does not, at present, require this ordering; it works even with interleaved vertex coordinates and face definitions as long as no face specifies a vertex with an index that appears after it in the database.
Programs that read polyface meshes from DXF would be wise to be as tolerant of odd vertex and face ordering as AutoCAD is.
