applying .ctb file to all layers?

[kwoky1988]

I am an new architectural student, recently working for a research center for summer. They sent me a .ctb file which included all the line weight i needed to complete my drawing. However, I am no idea how to apply them into the layers. I am currently copying the line weight from the table manually one by one. Is there anyway i can do it automatically?

 

Thank you very much!

A CTB file maps line weights to colours. In this case, don't set your lineweight in your layers (Leave it set at 0.0). Instead set the colour of your layer to the colour that represents the lineweight you want . You can get this information from the CTB file (pen table).

 

This technique is bit old fashoned now, but if it's what your client requires, then you should do it this way. IMO Your client should be able to help you apply their CAD standards. Why not give them a call and see if they have a written CAD standard you can refeer to? (i.e. One with a table that tells you which colour represents which line weight!) I would be supprised if you client didn't also have a list of layers that they wanted you to use. They probably have a table of layer names and colours ready to go.

Hi,

The CTB file is the plot style used for plot with standart of architectural firm.

You just transfert in plot styles directory

Go to Output tab/Plot panel/plotter Manager

and open plot styles

After when you setup to plot choose your plot style table see image below

But you have to use a firm template also ?

Bye

Probably this one can help:

Pablo, I believe the layer lineweight has to be set to Default for the ctb or stb to work.

[kwoky1988]

so, normally when i open layer manager, what is shown there is stb?

so i have to turn stb into ctb?

Are you talking about the Layer Properties Manager or the Layer States Manager?

 

If you received a ctb file that has lineweights already assigned then you shouldn't need to add anything to your drawing unless you want to assign lineweights within the drawing itself (in the Layer Properties Manager) and not within the ctb file. CTB and STB are plotstyle files.

i think it is Layer Properties Manager.

So why are you doing this then? The ctb file will take care of the lineweights.

[kwoky1988]

however, i have no idea which layer go with which line weight.

From your AutoCAD Help file.

 

Plot Style

 

"Changes the plot style associated with the selected layers. If you are working with color-dependent plot styles (the PSTYLEPOLICY system variable is set to 1), you cannot change the plot style associated with a layer. Clicking the plot style displays the Select Plot Style dialog box."

 

A color-dependent plot style file has been given to you. Open it using the Edit option found to the right of where the plot style name is shown in the Plot dialog window (see screen shot above - upper right hand corner of window). Then look on the Form View tab.

If you work with ctb plot style, you have to know what colour to to assign for each object of your drawing.

Example : Walls=>Blue, Doors=>Red etc.

But if your drawing use STB plot style in this case, lineweight are assigning with layer.

I have one question, why your firm sent you a ctb file.

normaly, they would be send a stb file also ?

[ReMark]

Named plot styles (STB) can be assigned to layers or objects.

 

Color-dependent plot styles (CTB) use an object's color to determine the lineweight.
