THE CURRENT VERSION OF THIS BORDER SHEET MUST BE USED TO
PROPERLY IMPLEMENT THE ELECTRONIC PAPERLESS ENVIRONMENT.
Figures 5.2.1 & 5.2.2 depict drawing and title block requirements. Cherry Point's
drawing and title blocks, including vicinity and area l ocation maps, are available in
AutoCAD format from the PM.
5.3 DRAFTING MEDIA
Unless otherwise instructed, complete sets of working drawings will be plotted and
submitted full size on paper using AutoCAD version 2002, in addition to the electronic
copy. Pre-Final and Final submissions will be submitted in electronic AutoCAD 2002
.DWG format on CD-R, ensuring that all individual drawing entities are BOUND into
one drawing file prior to writing to CD. When writing CDs, do NOT "close out" the CD
as this prevents the addition of more project data to the CD.
The orientation of NAVFAC drawings should be arranged with North toward the top
(or left edge, if better suited) of the plotted sheet and normal to the sheet borderline. On
individu al sheets, if the shape of the area dictates, North can be oriented between these
directions to accommodate the site. For example, on drawings having excessive
lo ngitudinal but limited lateral dimensions, such as those for roads and railroads, North
can be oriented obliquely to make the best use of available space. All discipline drawings
should be consistent in orientation in so far as practicable.
It is customary for a building plan to be oriented with the main entrance toward the
bottom or right edge of the sheet, depending upon the building shape. It is customary for
a building plan to also be oriented in the same orientation as the site plan.
5.5 LETTERING AND SHADING
NAVFACENGCOM uses the 35mm filming system file for retention of construction
drawings. Cherry Point uses half -size bidders' drawings. The quality of these reduced
prints is a direct result of the drafting efforts of the A&E preparing the AutoCAD
drawings. The finest cameras and most carefully controlled processing cannot produce
good results unless the original drawing is of a high quality.
Unnecessary detail, i.e. poor spacing, careless lettering, weak lines, and lettering
which is crowded and too small result in illegible films for full -scale and half -scale
reproductions. Make minimum gap between lines equal to one -half the letter height. The
standard text heights for a plotted full size drawing shall be 1/8" (3mm) for typical text,
and " (6mm) for titles, and 1" (25mm) maximum for project titles on cover sheets. For
existi ng features on civil drawings, a minimum text height of 0.1" (2.5mm) is allowed.
The ROMANS.SHX font file shall be used for all 1/8" (3mm) or smaller text.
