NCS Version 4.0 Errata

It has been brought to our attention that the Plotting Guidelines portion of NCS version 4.0 erroneously assigns line widths to display colors. Page PG-3 of NCS v4 includes a table with three columns identifying line width assignments to colors. The columns are labled MicroStation Line Width; Line Width mm; and Line Width in. However, members of the National CAD Standard Project Committee (NCSPC) approved an amendment (POP-013M-Taylor-29-Jun-06.xls) that did away with mapping colors to specific line widths. This is supported by text appearing above the table which states, "Since various screen [display] colors can be assigned to color numbers, only color numbers will be addressed." The NCSPC Steering Committee has been informed about the problem and they are reviewing it. We anticipate that an addendum will be issued to remove the columns from the table.

UPDATE: NIBS has agreed that inclusion of the line widths in the table is an error; and they have also acknowledged that text at the bottom of the table that reads, " *Red, Green, Blue (RGB) color values for gray may vary by plus or minus 5" will also be removed.
