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:

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.
