Geometry importation: DXF standard format

Conversion

The entities of initial file in DXF format are read and converted into Flux entities as in table below.

Entities of initial file are converted into …
POINT points defined by parameterized coordinates
LINE lines of segment type defined by extremity points
POLYLINE N lines of segment type
ARC, CIRCLE lines of arc type defined by origin, intermediary and extremity points
3DFACE faces of automatic type, with triangular shape, defined by a plane surface

Options for conversion

The options for conversion proposed to the user are of two types: general options for conversion available for all formats

  • particular options, specific to the format

Structure of a DXF file

A DXF file consists in 4 sections:

  • HEADER
  • TABLES
  • BLOCKS
  • ENTITIES

Only the ENTITIES and BLOCKS sections are interpreted by Flux.

Section Contents
ENTITIES information about the entities (geometrical data) : points, lines, faces ...
BLOCKS information about the texts, sizes, etc. (data of pictures)

Specific options

The options for conversion specific to the DXF format are presented in the table below.

Option Choice Description
Import in 3D or convert in 2D 3D (by default) Flux imports the data in 3D
2D the user choose to convert the initial file in 2D
Convert the ENTITIES yes (by default) Flux reads and converts data from the ENTITIES section
no Flux does not read the data contained in the ENTITIES section (ignored data)
Convert the BLOCKS no (by default) Flux does not read the data contained in the BLOCKS section
yes Flux reads and converts the data from the BLOCKS section
Import the EXTENDED ENTITIES* no (by default) the DXF file is imported in standard format
yes the DXF file is imported with the extended data *
Note: * The extended data (EXTENDED ENTITIES) are the data specific to every user. Contact us for more details about the using of this option.
