AIA NAS9300-100

Introduction

This document defines common fundamental concepts for long term
archiving and retrieval of CAD mechanical information for
elementary parts and assemblies. It details the "fundamentals and
concepts" of NAS9300-003 in the specific context of long term
archiving of CAD mechanical models.

CAD mechanical information is divided into assembly structure
and geometrical information, both including explicit and implicit
geometrical representation, Geometric Dimensioning and Tolerancing
with Form Features.

The NAS9300-1XX family is organized as a sequence of parts, each
building on the previous in a consistent way, each adding a level
of complexity in the CAD data model. This includes the detailing of
relationships between the essential information for the different
types of CAD information covered by the NAS9300-1XX family.

As technology matures additional parts will be released in order
to support new requirements within the aerospace community.

In scope

The present part describes:

• The fundamentals and concepts for Long Term Archiving and
Retrieval of CAD 3D mechanical information;

• The document structure of the NAS9300-1XX family, and the
links between all these parts;

• The qualification methods for long term preservation of
archived CAD mechanical information; more specially, principles for
the CAD validation properties and for verification of the quality
of the CAD archived file;

• Specifications for the preservation planning of archived CAD
information,

• Specific functions for administration and monitoring of CAD
archived mechanical models;

• The definition of Archive Information Packages for CAD
data.

Out of Scope

The following are out of scope for this part:

• Long Term Archiving of CAD 2D drawings.
