ENGINEERING DRAWING PRACTICES

1. INTRODUCTION

GP-435, Engineering Drawing Practices, Volume I of II, Aerospace and Ground Support
Equipment, establishes the conventions to be adhered to by engineering and drafting personnel in
the preparation, revision, and completion of engineering digital product definition data sets. This
manual sets forth the minimum requirements acceptable at Kennedy Space Center (KSC) for the
preparation of model-only, model and dependent drawing, and drawing-only digital product
definition data sets based on the engineering drawing and model requirements in the ASME Y14
series.

The engineering drawings prepared by KSC design personnel or contractors in the KSC drawing
format using KSC drawing numbers shall be known as government design activity drawings.

Although generally in accordance with industry practices and procedures, this manual does
contain specific differences and exceptions. This manual, while not intended as a manual of
instruction in the basic principles of drafting, does set forth the minimum requirements
acceptable at KSC. One of those requirements is that persons engaged in the preparation of
digital product definition data sets shall have a thorough understanding of the fundamentals of
modeling, drafting and geometrical dimensioning and tolerancing in order to produce
interpretable product definition data sets.

The widely accepted use of computer-aided design and drafting (CADD) and computer-aided
engineering (CAE) software and numerous packages thereof has necessitated the abandonment
of legacy manual drafting practices so long maintained by this manual at KSC. Typically
resulting from the use of these various CADD and CAE software packages is the existence of
software-package-provided or internally generated supplemental documents, such as design
manuals, computer-generated modeling manuals, and drawing manuals, that comply with
industry standards and may further define and standardize the creation of consistent digital
product definition data sets within the respective companies and organizations where they are
used.

The expectation now rests within the various companies or organizations producing government
design activity drawings to provide consistent product definition data sets that comply with the
industry standards discussed in this document. Clarifications of the industry standards and
additional requirements in this manual are specific to the KSC needs and are assumed CADD-
software-independent and not to cause undue burden or customization of CADD software.

Tailoring is permitted where unique contractor practices meet the intent of this standard.
Approval of tailoring is the responsibility of the lead discipline engineer for this manual as
identified in KSC-PLN-5400_LDE-LIST.

3.3 Notice

The following notice shall appear in the upper left corner of all sheets or views of government
design activity digital definition product data:

Notice: When government drawings, specifications, or other data are used for any
purpose other than in connection with a definitely related government procurement
operation, the United States government thereby incurs no responsibility or obligation
whatsoever; and the fact that the government may have formulated, furnished, or in any
way supplied the said drawings, specifications, or other data is not to be regarded by
implication or otherwise as in any manner licensing the holder or any other person or
corporation, or conveying any rights or permission to manufacture, use, or sell any
patented invention that may in any way be related thereto.

4. REVISION AUTHORIZATION DOCUMENT

4.1 Change Methods

Any changes to engineering drawings shall be recorded by Engineering Order (EO) or drawing
revision. Changes made by EOs should be incorporated into the drawing when the drawing is
revised. EO changes will be used as an alternate method of making drawing changes only when a
revision to the drawing is not feasible.

4.1.1 Changes by EO

An EO is used to change an engineering drawing only when it is impractical to revise the

drawing. When an EO is released, it becomes a permanent part of the drawing to which it is
applicable. Any change required to correct errors on a released EO requires the preparation of a
new EO. A new EO may cancel a preceding EO in its entirety only if no other subsequent EOs
are affected by the cancellation. A portion of an EO cannot be cancelled. All EOs are accounted
for in the drawing revision block at the next revision release, up to and including the last release.
An EO against one drawing number cannot be incorporated in another drawing number.

a. All EOs that are incorporated into the drawing should be listed as INC or incorporated in
the revision table.
b. If EO numbers were reserved and not subsequently used, they should be accounted for as
Not used in the revision table.
c. All EOs that have been released but have been cancelled by revision or subsequent EO
should be listed as Cancelled in the revision table.
d. An EO can be prepared on KSC Form 21-34 or an approved equivalent.
e. Changes made by EO should be incorporated into maintained drawings when the number
of outstanding EOs exceeds 10.
