Line Category

When I create new line styles, I noticed I can not add "<>" into the new line style names like the ones built in the program.  I assume that is the reason that my newly added line styles are not included in the line category list in dynamo.  Is there a way to fix this? Thank you.

I don't understand the question. Bracketed Line Styles just indicate the legacy/system line styles that cannot be removed.  They are hard-coded.

<> are reserved for system line styles. You can certainly include any line styles in a dynamo script.  Which node are you using?

I am using Categories.

My intention is to calculate the length of the building perimeter, so I create a line style named as building perimeter. I was expecting this line style will show up in the pull down list as other line style but unfortunately, both line styles I created are not there.

The node you use is a preselected list and only shows OOTB styles.

Search for the node Select Model Lines by Style, then use a code block node to enter the name of the line style.

With that said, there is an OTTB dynamo script under Dynamo Player that calculate my multiple lines that you select.

I got error messages; I am new to Dynamo, know limited nodes, no idea how to fix it.

@hliS658H I think these 2 posts from Dynamo Forum could guide you in the right direction or atleast give you a starting point

Get line style by name - Archi-Lab - Packages - Dynamo (dynamobim.com)

Get all project Line Styles and attributes - Revit - Dynamo (dynamobim.com)

Do close the topic if this helps.
