FIGURE 2: CALLOUT IDENTIFICATION FOR CROSS-SECTIONAL VIEWS

NOT TO SCALE – FOR ILLUSTRATION PURPOSES ONLY

K. External References. CG-LIMS STIP does not allow for the tracking and control of external reference files (XREFs). Therefore, all XREFs shall be embedded into the drawing file before submission to TIMB.

2-7

L. 3D Models.

1. All 3D Technical Data Packages (TDP) shall be developed in accordance with MIL-STD- 31000. The 3D Product Model shall be in an ISO 10303 STEP compliant format.

2. Tessellation lines may appear on drawings if desired. Hidden line removal, if required, shall be set. The drawing shall not require the user to set hide options prior to plotting.

3. 3D models and 3D model extracts such as solids, wire frames, or surfaces are acceptable.

4. Shading or rendering, while permitted, shall not be required to view or plot a drawing, and drawings shall be comprehensible without the use of shading or rendering.

M. Dimensions. All dimensions shall be in Paper Space with a DIMASSOC value of 2, and all DIMSTYLES shall adhere to the following:

1. Dimensions shall be associative and shall not be exploded.

2. Dimension styles preloaded within standard drawing templates shall be used and modified for scale purposes only when necessary.

3. Dimension style STANDARD shall not be used.

4. Fractional dimensions shall not be “stacked”.

5. Dimension appearance shall remain consistent with all present and new DIMSTYLES.

6. Fractional unit (CG-FRAC) DIMSTYLES add an inch mark (") to the dimension as a suffix and shall not be used for angular dimensions. These are generally used for objects measuring up to 72".

7. Architectural unit (CG-ARCH) DIMSTYLES are generally used for objects measuring 6'-0" and over.

8. Millimeter with inch unit (CG-MMIN) DIMSTYLES are used when the border template geometry and associated blocks have been scaled up by a factor of 25.4.

9. Paper Space DIMSTYLES automatically scale to the viewport when the variable DIMASSOC is set to two (2).

10. Scale Factor (SF) DIMSTYLES are used in Paper Space but have a “measurement scale factor” of DIMLFAC assigned. SF styles must have the variable DIMASSOC set to 1 to work properly. These DIMSTYLES may be copied and renamed to accommodate additional scales if the DIMLFAC is changed to match the scale factor.

2-8

N. Text.

1. Text shall be “Romans.shx” font, except for in cases where text is used in illustrations.

2. Text height in paper space shall not be smaller than 0.1 inches and shall be in accordance with ANSI-Y14.2. Text in model space shall be scaled appropriately.

3. Text width shall be at least .8 inches.

4. All text other than dimensions shall be placed on layer “Text”, unless the text is embedded within block geometry.

O. Line Types. Only line types native to AutoCAD™ shall be used.

P. Line Weights. SFLC standard drawing templates have predefined line weights which should not be altered without consent from TIMB.

Q. Color.

1. All drawings created or revised in AutoCADTM shall have the background set to Black.

2. All drawings shall be created using colors visible on both the digital .dwg file and the plotted drawing.

3. The list of authorized colors for plotting are embedded in each SFLC standard drawing template.

R. Revision Symbols.

1. An attributable triangle style revision symbol (rev triangle) shall be used to identify changes made as part of a revision to a drawing.

2. Rev triangles for each revision shall have the appropriate revision letter inside the triangle and the revision item number in superscript outside of the top right of the triangle (REVTRIBLK on any standard template).

3. Other attributes embedded in the Rev Triangle Block are for amplifying information and are not required.

S. Wiring Databases. Wiring databases are documents that detail electronics connections. They are formerly known in the Surface community as Computer Oriented Electronics Databases (COEDs), and this name is used interchangeably with “wiring databases”. The term COED may still be found throughout official documents and used in day-to-day discussions (See TS 085-0 for more information).

1. Published PDF files for wiring databases shall include front matter developed using AutoCADTM, using the Wiring Database standard template.

2. Front matter files shall contain a Coast Guard Title, Drawing Number Block, USCG

2-9

Approval Block, Command or Contractor Block, Revision Block, Applicability Block, Sheet Revision Status Table, Special Notations Table, and Reference Plans Table.

3. Additional sheets within the CAD template may be utilized if space is required for continuation of information.

4. Existing files may be found where the wiring database (COED) is embedded into the AutoCADTM front matter file. These are no longer utilized and shall be deleted when the drawing is revised. CG-LIMS STIP stores the master database file, and this embedded file is no longer required.

T. Proofing Drawings Prior to Submission. Prior to submitting either a new or revised drawing to TIMB for check-in, several steps shall be followed:

1. Remove any unused block definitions, layers, line types, etc., to keep file size to a minimum.

2. Remove any geometry present in Model Space that is not depicted in a Paper Space view, unless needed for design development.

3. Remove any geometry or text outside of the drawing borders in Paper Space.

4. If a drawing was associated to a sheet set, the association must be removed prior to submission to avoid the lost set association error. To remove the association, open the drawing in the absence of the sheet set file and select “Remove” on the Lost Set Association dialog and save the file.

5. Delete any unused layout tabs.

6. Delete any unattached XREF paths and embed any XREFs.

7. Zoom to Extents on Sheet 1 and save the drawing in a format compatible with the most current version of AutoCADTM installed on the CGDN.

U. Plotting Instructions.

1. Plotting shall be in accordance with USCG Color-Dependent Plot Style Table, found within all SFLC standard drawing templates.

2. Plot Scale shall be set to “1:1” with 1 mm = 1 units for plotting the drawing to actual size.

3. All layers shall be turned on, except for the “No-Plot” layer, which contains special plotting instructions.

2-10

V. Signature Authority. Drawing Signature Authority is established in Chapter 13, Section E of the Naval Engineering Manual COMDTINST M9000.6 (series).
