3.4 Global environment

An optional global environment block provides a few ways to affect the entire scene. The block must appear as the last text in the sketch input file. It may include definitions, but note that previous definitions at the top level (not nested inside blocks) are also available.

Syntax:

     global { environment_settings }

The contents of environment_settings are discussed in the sections that follow.

• Global options: Attributes of the entire drawing.
• Camera: A final camera transformation of the scene.
• Picture box: Setting the bounding box and 2d clipping.
• Frame: Adding a box around the drawing.
• Language: Setting the output language.
