How to use linetypes?

[Cyberduke01]

I am trying to change the different type of lines to draw. I followed the tutorial on adding the different lines seen here:

https://ezdxf.readthedocs.io/en/stable/tutorials/linetypes.html

But when I somehow not finding how to change the type of the line I am actually drawing, here is an example of what I am trying to achieve:
msp.add_line(start,end, dxfattribs={linetype: 3})

This is not how to ask question.~

1. Please show the full code, and save to dxf file.
2. Then upload the dxf file(compress to zip) to prove your concern.

Hi, please find that here: as shown it is still just a solid line.

`
import ezdxf

doc = ezdxf.new('R2010')
msp = doc.modelspace()

msp.add_line((0,0), (10,10),dxfattribs={"linetype": "DOTTED"})

doc.saveas("TEST.dxf")
`

Most DXF resources are referenced by their name like ... dxfattribs={"linetype": "DOTTED} or entity.dxf.linetype = "DOTTED", for more information about the common graphical DXF attributes see the docs.

Please see my answer to the above post, that still shows my problem.

Resources are not setup by default, see see docs for ezdxf.new().

Solution: the word "dotted" doesn't work, when changed to something else like "Center" it worked.

Problem solved, thanks for the help

Just to follow up since I had similar question.

I don't think it's correct to say that "dotted" doesn't work. As @mozman pointed out you need to add the resources you are going to use, the key is the definition of linetypes and there is a good tutorial for linetypes
