    Question NCS fire rated Lines

    Does any one have, or know where to get the NCS fire rated line types found on pages UDS-06.8 through 9.

    Thankyou.

    It has been a while since I tackled that one for my office, based on US National CAD Standard Version 2. I suppose they have not changed the specifications since then. I vaguely recall that at least some of the linetype specifications were semi-vague, in that they did not give a length for the long dashes between the short dash pattern.

    My office uses imperial units and a paper space linetype scale factor of 0.375, so the mm dimensions specified in the US NCS were translated to inch units, then multiplied by 8/3, if I am recalling correctly. You may want to check that math, since I do not have access to the US NCS right now, and this was done more than four years ago.

    ADT used to have a pull-down for indicating fire walls, but it was just a dumb p-line. you had to make breaks in the p-line for doors and windows to show.

    I have used some third party applications to create patterns that appear within the wall thickness. They aren't ideal, because the patterns appear as a series of lines, instead of one solid thickness. They work, though, because they automatically break at the openings.

    We have a zero-width component in the middle of our rated walls, set to a hefty lineweight, that works well for 1/8" or 1/4" = 1'-0" plans, and apply the linetype as a Material Definition to that component. We only show the Shrink Wrap component at that scale, so all walls are essentially two parallel lines, with the addition of the "fire tape" line in the middle of rated walls. (And yes, I am old enough to have added "fire tapes" with Chartpack tape back in the dark ages of manual drafting.)

    Go to your documentation tool catalog look under miscellaneous/fire rating lines.

    I have finally had a chance to see Version 4, and the linetypes have been changed. A square diamond shape, one for each hour of rating, is used between straight segments. An "S" is added for smoke barriers. One way to achieve that would be to use a complex linetype with embedded characters. The Wingdings font has a square diamond character that can be used.

    The NCS is still the NCS. It just moved its home from NIBS to BSA.

    Thankyou.
    I just thought I would reply to this thread because I had searched these forums before looking for this very same thing, but like you, didn't find what I was looking for.

    As a result, I ended up researching how to create shape files (shp & shx) to create the linetypes from scratch.

    Look HERE for the linetype code and supporting SHX file.

    I'm assuming others looking for the same thing may want this information too.
