How do we change a linestyle , how to get the linestyle value?
Johannes
Johannes,
You can download a custom node from archi-lab.net that will get a line style for you:

Then obviously you have to collect all lines that you wish to change the line style for. Lines are category OST_Lines and can be either Drafting or Model lines. Just filter those out in any fashion you wish. Let me know if you need more help.
In 0.6.3 I did this by pushing the model line to another subcategory (that’s basically what a linestyle is), but working with subcategories does not seem to possible in Dynamo 0.7 … 
I filed an issue about this on GitHub a while back: https://github.com/DynamoDS/Dynamo/issues/2460
This is as easy as getting your lines, getting the line style (see my first comment) and then doing this:
Start Transaction
for line in yourLines:
lien.LineStyle = newLineStyle
End Transaction
Andreas,
What did you have problems with?
Konrad,
thank´s, it works !
Cool, looks like it’s a lot easier in a project file than in a family file (and quite a different method as well).
Nice work, Archi-Lab nodes have been really helpful, I’m glad you solved your issues.
I have a related question. How would someone rename the line styles in their project?
Example: “xxx - Thin Lines” --> “Thin Lines - xxx”
I have been able to do this with family names, but having some issues with line styles.
Where did “Get Line Style By Name” go (or turn into) in Dynamo 0.9.2?
