Stage of conversion with options

Introduction

The first stage of import is the stage of conversion of the imported geometry into the Flux format.

Operation principle

The principle of operation of the import is as follows: all the geometric entities of the initial file (specific to the standard and proper formats) are converted into the Flux format (geometric entities of type Point, Line, Face and Volume) in the final file.

Conversion of entities

The entities of the initial file are read and converted into the Flux entities. The summary table is presented below:

The file format … CAD entities contained… Convert into Flux entities …
IGES / STEP points points defined by parameterized coordinates
lines

lines of type:

  • segment defined by extremity points
  • arc defined by origin, intermediary and extremity points
  • curve (for the unspecified lines)
faces

faces of type:

  • automatically defined by plane, cylindrical or conical surfaces
  • uneven type, defined by any kind of surfaces
DXF 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
STL VERTEX points defined by parameterized coordinates
FACET faces of automatic type, with triangular shape, defined by a plane surface
FBD points points defined by parameterized coordinates
lines

lines of type

  • segment defined by extremity points
  • arc defined by origin, intermediary and extremity points
faces automatic faces
geometric parameters geometric parameters
regions regions

Options for conversion

To perform the data conversion, different options are available to the user.

There are two types of options:

  • general options, available for all formats
    • choice of a coordinate system: locates the imported geometry in the Flux project
    • choice of the unit: chooses the units of the device dimensions
    • choice of precision: defines the minimal distance that enables the distinction of two points
  • particular options, specific to the format

Only the general options are described in this section.
