# NAME

GDX_PRECISIONS - Precisions

# GENERAL DESCRIPTION

A GDX Precisions entity is an entity to store the model tolerance when a GDX model is saved or restored. The functions gdx_RestoreModel and gdx_SaveModel must be used to set or restore the GDX tolerance values in a Precision entity.

# DDF SPECIFICATION

    entity 110:0 GDX_PRECISIONS "Precisions" {

    double
    PRECISION

    double
    ANGLE_PRECISION

    };

    };

# FIELD DESCRIPTIONS

PRECISION

The maximum linear distance between two points in model space where the points are considered coincident. Corresponds to the GDX model space tolerance.

ANGLE_PRECISION

The maximum angle between two vectors where the two vectors are considered to be parallel. Corresponds to the GDX angular tolerance.

# RESTRICTIONS

Each GDX model should have zero or one precision entity.
