CAD Drawings / 3D-CAD (CATIA) Models; Identification
(Marking) of Parts / Assemblies of the Products in CAD
Drawings or in 3-D CAD (CATIA) Models which Require
Documentation
Foreword
This standard defines the identification of parts, assemblies, standard parts and individual features
in CAD drawings and, using the 3D-Master method, also in 3D CAD (CATIA) models which require
documentation.
In this standard, the expression "documentation required" actually refers to two types of evidence:
safety-relevance (DS) and certification-relevance (DZ).
The codes DS und DZ are intended for the special provision of objective evidence for the relevant
components and systems. The abbreviations DS and DZ are formed of the first letter of the German
term for the type of relevance applicable plus a leading D.
Both types of documentation requirements are applicable separately in CAD drawings and 3D CAD
(CATIA) models. When applied, they represent binding instructions and form a prerequisite for
passing on data to subsequent systems along the process chain.
Changes
In comparison with edition 2004-05, the following changes have been made:
?Restriction of application to Mercedes-Benz passenger cars lifted
?Standard completely revised
NOTE: No guarantee can be given in respect of this translation. In all cases the latest
German-language version of this Standard shall be taken as authoritative.

4 Identification for Parts / Components in CAD Drawings
The scopes defined in coordination with the person responsible for the parts shall be identified in CAD drawings according to Section 4.
Identification includes parts and assemblies as well as individual features of a component requiring docu-mentation for the different drawing types:
?Component drawing/General assembly drawing in single-sheet/multi-sheet version
?Table drawings for design drawing (KZ) – see parts in single-sheet/multi-sheet version
? Supplier drawing
4.1 Identification of Documentation Requirement on a Detail / Assembly Drawing
To identify parts/assemblies requiring documentation, the additional field "Documentation required according to MBN 10 317" shall be used; for a representation of an additional field, refer to Fig. 1.
Fig. 1 Additional field "Documentation required according to MBN 10 317" for a general assembly/component drawing; not true to scale
The additional field contains relevance types DS and DZ. Two columns are available for entry of the documentation requirement: “Art/type“ and “Anzahl Merkmale/number of features“.
If the additional field is inserted into a CAD drawing, then the relevance types shall always be entered. The system default for the possible entry fields is zero (0).
To make an entry, the letter X or the character zero ( 0 ) may be used for each relevance type of an SNR. If required, the default zero (0) shall be changed by entering X.
?Meaning of possible entries for column “Art / type“
Entry X = corresponds to documentation required “yes“
Entry 0 = corresponds to documentation required “no“ (no documentation required)
Data entry version for: Complete part or component requires documentation
Entry X in column “Art/type“ and default entry zero (0) in column “Anzahl Merkmale/number of fea-tures“ is maintained.
?Meaning of possible entries for column “Anzahl Merkmale / number of features“ This column shall be completed if there is a requirement for individual features subject to docu-mentation. The total of all features for each relevance type of an SNR shall be entered here.
The completion of this column is always related to the column “Art/type“.
Data entry version for: Number of features subject to documentation
Entry X in column “Art/type“ and total number of features in column “Anzahl Merkmale/number of features“.
4.1.1 Identification on detail / assembly drawing – single-sheet version
For this drawing version, the additional field "Documentation required according to MBN 10 317" shall be added near the title block according to Figure 1 and completed in line with the relevant specifications.
4.1.2 Identification on detail / assembly drawing – multiple-sheet version
For this drawing version, the identification of the documentation requirement shall be marked on the cover sheet (sheet 0) of a multi-sheet drawing.
The additional field "Documentation required according to MBN 10 317" shall be added according to Figure 1; where it is added, an entry requirement for the relevance types always exists. Procedure for the entry as under Section 4.1.
If in addition individual features with document requirement are needed on some/all subsequent sheets, a further additional field according to Figure 2 shall be used on each affected follow-on sheet.
Fig. 2 Additional field "Documentation required according to MBN 10 317" as element for follow-on sheets of a multi-sheet drawing; not true to scale
Where the additional field has been added, it shall be completed on the follow-on sheet. The system de-fault for the possible entry fields is zero (0). If required, the default zero (0) shall be changed by entering the total sum of all features for each affected follow-on sheet.
Data entry version for: Number of features subject to documentation
Entry of total, e.g. 3features, in column “Anzahl Merkmale/number of features“meaning that on this follow-on sheet 3 DS / DZ features exist.
Finally, the sum total of all features of the follow-on sheets shall be entered in the additional field "Documentation required according to MBN 10 317" on the cover sheet (sheet 0).
Note
Follow-on sheets without required feature identification do not receive an additional field according to Fig-ure 2.
4.2 Identification for Design Drawing (KZ) – see Parts in a Table Drawing (Compo-
nent/General Assembly Drawing)
4.2.1 Identification of design drawing (KZ) – see parts on a single-sheet drawing
To identify parts / assemblies requiring documentation for the representation type "Parts representation without separate drawing", the data field “D-Pflicht/required MBN 10317“ shall be used.
Data field representation, Fig. 3.
Fig. 3 Data field “D-Pflicht/required MBN 10317“" as an element of the additional title block of a CAD drawing; not true to scale
When added to a CAD drawing, completion is required according to the relevant specification.
Two entry variants are available for the completion of the columns DS and DZ of the data field:
1. Entry of design drawing (KZ) – see part as complete documentation required
2. Entry of individual features with documentation required of design drawing (KW) – see part only The system default for the possible entry fields is zero (0).
For the 1st entry variant, an X or zero (0) shall be entered in the relevant columns; for the meaning of the letter X and the character 0 (zero), refer to Section 4.1., i.e. if required the default zero (0) shall be re-placed by entering X.
For the 2nd entry variant, only the required number of features shall be entered in the corresponding col-umns of the relevance type.
4.2.2 Identification of design drawing (KZ) – see parts on a multiple-sheet drawing
To identify parts / assemblies requiring documentation for the representation type "Parts representation without separate drawing", the data field “D-Pflicht/required MBN 10317“ shall be used. Data field repre-sentation, Fig. 3.
The data field shall be added to the additional title block of a design drawing (KZ) – see parts.
If in addition individual features with document requirement are needed on some/all subsequent sheets, a further additional field according to Figure 2 shall be used on each affected follow-on sheet.
When added, it shall be completed on the follow-on sheet according to Section 4.1.2.
Finally, the sum total of all features of the follow-on sheets shall be entered in the data field, Figure 3, of the additional title block of the design drawing (KZ) – see parts.
4.3 Identification of the Documentation Requirement on an Externally Created CAD
Drawing (Supplier Drawing)
Identification of parts / assemblies requiring documentation on an externally created CAD drawing shall be executed in analogy with company-specific CAD drawings, Section 4.1 or 4.2.
5 Identification of Individual Features Requiring Documentation on a CAD
Drawing
A symbol shall be used to identify features requiring documentation on CAD drawings. The symbol con-tains the relevance type required according to the specifications and an increment number.
The increment number depends on the number of required features in the document; the increment is consecutive and ascending and shall always start with the character 1 for the first feature.
The symbol with the relevance type “DS” or “DZ” shall be created and inserted close to the relevant feature or using a reference line connected to the feature. For a representation of the symbols, refer to Figures 4 and 5.
For other informative sample entries of symbols on CAD drawings, refer to Annex A.
Fig. 4 Identification symbol for a 1st feature with safety relevance; not true to scale
Fig. 5 Identification symbol for an 11th feature of at least 11 features; not true to scale
If one or several features requiring documentation are entered on a CAD drawing, then the respective total of the features shall be determined to provide an overview of all features. For entry of the totals in the drawing versions, refer to Section 4.
When a feature is removed from a total set of features, then the numbering shall not be changed; it is sufficient in the change note to indicate that the respective symbol was removed, e.g. ”DS 4 removed”; the total number of features shall be adjusted in the relevant SNR. It is not acceptable to reassign a feature which has been removed.
Special feature case
The feature “Functional Safety By Self-Test“, i.e. the safety function of an electronic component realized by inherent system monitoring functions, is expressed by the short form DS_I. The identification of DS_I is only required on CAD drawings and in a 3D CAD model (master data sheet). For the representation of an application example, refer to Fig. A.4 Annex A.
6 Identification of Standard Parts Requiring Documentation
The elements screws, nuts and rivets are excluded from the scope of standard parts requiring documenta-tion. For these elements, a special requirement exists regarding the provision of evidence concerning product safety.
6.1 Rule for Identifying Standard Parts Requiring Documentation
Whenever the status of a standard part requires that the part have documentation, a CAD text drawing/CAD drawing with an A-SNR is required.
On this drawing, the complete standard part data of the part shall be specified/shown and the additional field "Documentation required according to MBN 10 317" shall be added according to Figure 1. For provi-sion of evidence, refer to Section 4.1.
6.2 Procedure for Identifying Standard Parts Requiring Documentation
The fact that a standard part requires documentation shall be communicated to the standards department responsible for the Mercedes-Benz vehicle business. A-basic number allocation, creation of 3D-CAD model and specified CAD drawing by standards department.
7 Provision of Elements of Documentation Requirement on CAD Drawings
All the elements needed to fulfil the documentation requirement on CAD drawings (“additional field and data field“) are availabe for use in the CAD system "CATIA", versions V4 and V5. In addition, the creation of the identification symbol is described.
?The elements for CATIA V4 are provided in the detail library “CATIA:MB#ZNORM.P#019.MAP“ within the family “Additional fields“. The identification symbol is created using font –EUDT_MCF- and font size 3,5 or 5,0 mm with TEXTD2-CREATE-TEXT-SIMPLE or TEXTD2-CREATE-TEXT-LEADER with frame setting W (whole text) and frame type (framing) RECTP11.
?The elements for CATIA V5 are provided in the catalog “#CATALOG.MBZNORM_19 “ under “ZUSATZFELDER.catalog“. The identification symbol is created using font Monospac 821 using font 3,5 or 5,0 mm with text / text with leader and “frame” (Rechteck) setting.
8 3D-Master Method: Identification of Documentation Requirement in 3D CAD
Models of Version CATIA Version V4
For parts and assemblies created according to the 3D-Master method no CAD drawing exists. The identi-fication of the documentation requirements and of features is effected in the 3D-CAD model with master data determined by the persons responsible for the parts.
Section 8 covers the identification in 3D-CAD models of CATIA Version 4.
8.1 Identification of Documentation Requirement for Components in CATIA Version V4 The identification of the documentation requirement for components is made in the master data within the Comment file.
