Order of lineweight to color mapping

Anonymous · ‎03-07-2003

I need help convincing my companies main office to change our company
standard pen mappings on .ctb files.

What is considered "Main Stream" as far as pen weights for the primary 9
colors in a .ctb. Meaning, how many of you start with color 1 (red) as the
thickest and go thinner down the list to color 9?

Any help from you guys (or gals) would be great....

There's a lot more ammo for you... or a lot more confusion on the way!

Which color table??
R2004 introduces 256 + RGB + HSL colors... 16+MM colors...

Use lineweights and toss the color map!
Migration Assistance will help transitions... (so I hear, nobody here has
used it yet)

(also, colors are meaningless when using STB plot tables)

I work for a Civil Engineering firm using 2000i BTW....

Switching to STB's is not a possibility (yet) for us, so I'm speaking
strictly CTB's here.

At my current location, colors 1-9 are the same weight with each grouping a
different lineweight. At my previous employer, 1 was thinnest and moving up
to 4 then repeating with every 4th color the same thickness, (4 separate
thicknesses).

We don't set pen weights by color any more. We set them my layer. Users are
much less likely to change the lineweight of a layer than they are the
color. This has cut way down on problems when people change the color of a
layer so they can "see it better" and forgetting to reset it before
plotting. You can set up the lineweights in your template file so if objects
are created on the correct layers they will plot at the correct weight no
matter what color they, or the layer they are on, is set to.

I second that ! STB is the way to go.

one trick we did was to insure that we had a bunch of colurs at the high end
that mapped to shades
also made sure that titleblock layers used colours unique to all other
layers - this way as we developed the colours we never affected the
titleblock

Hey Peter - how is lineweight assigned during entity creation? or after? or
do you use bylayer?

we use the ctb model and push objects into the various layers
(the neat part is moving objects from existing to new to demolition layers
and having the linetype and color set the display and plotted output to
exactly what you want)

You can change individual entities with celweight (like cecolor, celtype)

I use bylayer when layers are defined.
I use a similar mechanism for existing/demolition... push the object to a
corresponding layer....

(defun get_linewts() ;;; Set up basic lineweights
(setq lw_n (list ' "0.45" "0.18" "0.40" "0.25" "0.30")
;; ^ the predominant line weight settings ^

lw_Text (list ' "0.25" "0.18" "0.25" "0.20" "0.35")
lw_heavy0 (list ' "0.50" "0.20" "0.50" "0.20" "0.30")
--- etc ---
)
)

In our setup... the Layer's line type/ weight/ initial color are set up by
taking element 1 from each list (above) for NEW objects/ element 2 from
above for Existing objects... and on through the standard construction
phases.

While the issue of using CTBs over STBs and vice versa is getting the
most attention, I thought I'd aswer your question.

There is simply no reason to assign pen weights based on increasing
ACI color number (meaning red = color 1 = "pen 1", yellow = pen 2,
etc) in increasing pen thicknesses.

Autodesk assigned the ACI numbers almost arbitrarily, and they were
never meant to be assigned to pen thicknesses in this way, at least
not intentionally.

You should assign pen weights based on what you want to see on screen.
I know people who have a hard time seeing red on a black screen, but a
gray or white background is equally unacceptable because of the use of
Yellow. So why assign a hard to see color to a "popular" pen weight?

Pick colors and pen assignments based on how you want the drawings to
look on screen for maximum user comfort, and screw the ACI color
number as a guide. People will get used to it.

Hear Hear!

I hate getting files from architects in joint venture who think it's great
to have almost invisible lines represent light plotted lines - have they
never heard of plot preview or LW?

Remember - some people are colorblind (got one here)
So color should really be a "suggestion" with a standard Start point and
strategy to preserve familiarity among fellow users... then leave it to the
users to adjust...

(as I said, it's lineweight that matters!)

And for those grays ... we use the 250's screened to "nearly-match" the
screen appearance

Is anyone using, or encountered another firm who is using, the National CAD
Standard color mappings?

Anonymous · ‎03-17-2003

As standards go, I have not seen one "main stream" fit everyone.
For CTB plotting, the color table that I have had the most success with is
assigning everything that ends in a zero to a pen width (0.20mm for
example).

Everything that ends in a 1 another width, 2 another width, and so on.

You can further divide this by adding 1mm to pens in the 100 range. A pen
width of 100 might plot 1.20mm, and a color of 10-90 might plot 0.20mm

Pens in the 200 range might be shaded values with the same pen width
designation.

But I think I'm liking the "lineweight by object" option instead of plotting
using CTB or STB as we are accustom to.
