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

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

A DXF file consists in 4 sections:

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)

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
Import in 3D or convert in 2D	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
Convert the ENTITIES	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
Convert the BLOCKS	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
Import the EXTENDED ENTITIES*	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.
