Group code Value type 0 Identifies the start of an entity, table entry, or file separator. The text value that follows indicates which. 1 The primary text value for an entity. 2 A name; Attribute tag, Block name, etc. 3-4 Other textual or name values. 5 Entity handle expressed as a hexadecimal string. 6 Line type name (fixed). 7 Text style name (fixed). 8 Layer name (fixed). 9 Variable name identifier (used only in HEADER section of the DXF file). 10 Primary X coordinate (start point of a Line or Text entity, center of a Circle, etc.). 11-18 Other X coordinates. 20 Primary Y coordinate. 2n values always correspond to 1n values and immediately follow them in the file. 21-28 Other Y coordinates. 30 Primary Z coordinate. 3n values always correspond to 1n and 2n values and immediately follow them in the file. 31-37 Other Z coordinates. 38 This entity's elevation if nonzero (fixed). Output only if system variable FLATLAND is set to 1. 39 This entity's thickness if nonzero (fixed). 40-48 Floating-point values (text height, scale factors, etc.). 49 Repeated value - multiple 49 groups may appear in one entity for variable length tables (such as the dash lengths in the LTYPE table). A 7x group always appears before the first 49 group to specify the table length. 50-58 Angles. 62 Color number (fixed). 66 "Entities follow" flag (fixed). 70-78 Integer values, such as repeat counts, flag bits, or modes. 210, 220, 230 X, Y, and Z components of extrusion direction. 999 Comments |
