STL-IO

A Godot/GDScript addon to import/export in the STL file format.

Setup

1. copy the addons/stl-io directory into your addons
2. activate it in the plugins settings.

Overview

This addon is pretty simple with 3 classes:

• STLIO has the plumbing to enable the editor
• STLIO.Importer for manual imports
• STLIO.Exporter for manual exports

Usage

In The Editor

STL files should be usable as ArrayMesh resources as soon as the addon is activated.

Import

The importer returns either a Variant that is either an ERROR or an ArrayMesh.

var mesh :ArrayMesh = STLIO.Importer.LoadFromPath('/path/to/file.stl')

STLIO.Importer.LoadFromBytes is also available for custom use cases.

Export

The exporter exports all surfaces of an ArrayMesh to its destination.

var mesh :ArrayMesh = ...
STLIO.Exporter.SaveToPath(mesh, '/path/to/file.stl')

STLIO.Exporter.SaveToBytes is also available for custom use cases.
