Angle file structure

The structure and naming in Angle files are pretty straightforward, so one can read and understand them without much effort. Here, we will explain the structure of all the file types in Angle.

To keep it as simple as possible, here we will not use any XML Schemas to describe the formats of XML documents, but plain words.

In our examples we will use blue letters to distinguish XML elements, attribute names will be displayed in red letters, and their values in purple. Comments will be displayed in green letters. Mandatory elements and attributes will be in bold.

All attribute values must be enclosed with quotes. Different types of values are indicated by the following abbreviations (in italics):

• str – Non-empty string (text).
• str0 – String, which can be empty (i.e. zero-length).
• float – Positive real number.
• float0 – Non-negative real number.
• int – Positive integer number.
• bool – Logical value: only “yes” or “no”.

Decimal separator for real numbers is a point (“.”), regardless of the settings on your computer.

The first line in every Angle file is the same and it defines the XML standard and encoding used, followed by a single “angle” element, which encloses the rest of the document:

<?xml version="1.0" encoding="utf-8"?>
<angle generator="ANGLE" version="5.0" build="5.0.0.274" units="mm">
  ...
</angle>

The element “angle” must have three attributes specified:

• generator: Must have the value of "ANGLE".
• version: Minimum version of Angle required to open the file.
• build: Version of Angle which created the file.
• units: Units of length used in the file. Allowed values are: “mm” (millimeters), “cm” (centimeters) and “in” (inches).
