Note that because this only requests 2D points, it does ' not include the Z coordinates (codes 30 and 31). This subroutine requires five parameters, ' the DXF file name, the number of sides for the polygon, the X ' and Y coordinates for the bottom end of the right-most side ' (it starts in a vertical direction), and the length for each ' side. ' WriteDXFPolygon creates a minimal DXF file that only contains ' the ENTITIES section. The following Visual Basic 6 subroutine constructs Such layers are automaticallyĬreated with color 7 and the CONTINUOUS linetype. The ENTITIES section, you can reference layer names even though you Section must appear before the ENTITIES section. No block definitions are used in the drawing, the BLOCKS section In the LTYPE table, this table must appear before the LAYER table. Need to make entries, and the entire TABLES section can be dropped Of the tables in the TABLES section can be omitted if you don't AutoCAD lets you omit many items inĪ DXF file and still obtain a usable drawing.Įntire HEADER section can be omitted if you don't set header variables. Must maintain consistency within the drawing in order for AutoCAD toįind the file acceptable. Writing a program that creates a DXF fileĬan be more difficult than one that reads a DXF file, because you
