Description |
|
100 |
Subclass marker (AcDb2dPolyline or AcDb3dPolyline) |
|
66 |
Obsolete; formerly an “entities follow flag” (optional; ignore if present) |
|
10 |
DXF: always 0 APP: a “dummy” point; the X and Y values are always 0, and the Z value is the polyline's elevation (in OCS when 2D, WCS when 3D) |
|
20 |
DXF: always 0 |
|
30 |
DXF: polyline's elevation (in OCS when 2D; WCS when 3D) |
|
39 |
Thickness (optional; default = 0) |
|
70 |
Polyline flag (bit-coded; default = 0): 1 = This is a closed polyline (or a polygon mesh closed in the M direction) 2 = Curve-fit vertices have been added 4 = Spline-fit vertices have been added 8 = This is a 3D polyline 16 = This is a 3D polygon mesh 32 = The polygon mesh is closed in the N direction 64 = The polyline is a polyface mesh 128 = The linetype pattern is generated continuously around the vertices of this polyline |
|
40 |
Default start width (optional; default = 0) |
|
41 |
Default end width (optional; default = 0) |
|
71 |
Polygon mesh M vertex count (optional; default = 0) |
|
72 |
Polygon mesh N vertex count (optional; default = 0) |
|
73 |
Smooth surface M density (optional; default = 0) |
|
74 |
Smooth surface N density (optional; default = 0) |
|
75 |
Curves and smooth surface type (optional; default = 0); integer codes, not bit-coded: 0 = No smooth surface fitted 5 = Quadratic B-spline surface 6 = Cubic B-spline surface 8 = Bezier surface |
|
210 |
Extrusion direction (optional; default = 0, 0, 1) DXF: X value; APP: 3D vector |
|
220, 230 |
DXF: Y and Z values of extrusion direction (optional) |
Xdata with the "AUTOCAD_POSTSCRIPT_FIGURE" application ID may follow a polyline entity. This contains information related to PostScript images and PostScript fill information.
