# STL Exporter

Section Name [ENF2STL]

## AsciiMode

Specify the file format of output STL file.

- Default Value: 1
- Values
  - 0: In binary format
  - 1: In ASCII format

## ApxLengthTol

Specify the maximum distance tolerance for approximation in generating polygon from B-rep by tessellation. (Unit: mm)
Specify by a positive real number. The default value will be used when this is not set, or an invalid value is set for this.

- Default Value: 0.1

## ApxAngleTol

Specify the angle tolerance for approximation in generating polygon from B-rep by tessellation. (Unit: degree)
Specify by a positive real number. Please ensure that the value is greater than zero. The default value will be used when this is not set, or an invalid value is set for this.

- Default Value: 10

## ConvertPolygonFromBrep

Specify whether and when to tessellate B-rep in ENF to generate polygon and convert to STL file.
Please note that polygon in ENF will always be converted to STL file when available regardless of this value.

- Default Value: 2
- Values
  - 1: Tessellate B-rep for parts that do not have polygon
  - 2: Tessellate B-rep only when all parts do not have polygon
