    Revit OpEd: Line Styles Embedded in Families

    Reading a thread at AUGI tonight prompted this post. Line Styles aren't a thing in Revit families, the option is disabled if you attempt to review them while in the Family Editor UI.

    The family discussed in the thread seems innocent enough until it is loaded into a project file. These are the line styles that are in the default template (imperial).

    This is the same dialog after loading the family; nearly 100 more (98) line styles show up.

    The culprit is Transfer Project Standards (TPS). It is easy to transfer line styles from a project to a family. We need Object Styles in families not Line Styles. Make sure you don't select Linestyles when/IF you use TPS.

    If you've already got many rogue Line Styles you can delete them from the project and in Revit 2016 you can select more than one at a time and click Delete. Just remember if Delete is disabled then you've got a built-in (system) line style selected.

    What about cleaning out the family itself? They don't give us a tool to do that. Purge Unused doesn't see them unfortunately. Robert Bell, in the AUGI Thread, offers a solution though. Load the bad family into a empty template (choose the None option for example). Delete all of the line styles you don't want. Then Save the family and overwrite the original. If the family is already loaded into your project just do the same thing, delete the line styles (it's just a little harder to tell) and Save the family to overwrite the original.

    While you're at it, don't use TPS on Line Patterns, like shown in the image above. You'll probably get many more than you really want too. Those can be deleted a bit more easily though.

    I checked the Autodesk Exchange Apps site to see if any offer a way to purge line styles from families. I found one that does it for projects but none that claim to do it for families; at least not based on searching for that criteria. It might be something Dynamo can be used to resolve; I'll have to check into that.
