Before
After
### Directionality for Parallel Work Lines
You can now choose the direction in which you want to offset parallel work lines when creating or editing them.
### Persisted Work Lines
Work Lines are no longer removed when you refresh or close a project. Instead, you can now Delete All Work Lines from the Work Lines collection in the right panel or multi-select and delete just the ones you're done with.
### Set Component Type for Feature Pattern Trusses
If you create a truss using the feature pattern method, you can change its loading type between Roof and Floor from Component Properties without using Convert to Settings.
