In which dialog can the start and end posts for a railing type be adjusted?

The start and end posts for a railing type can be adjusted in the "Edit Baluster Placement" dialog. This dialog allows users to manage the placement of balusters, which includes configuring the start and end posts. The ability to adjust these elements is essential for accurately defining railings’ structural and aesthetic properties. Within this dialog, users can specify how and where these posts appear, providing better control over the railing design to meet both safety and visual expectations.

The other options, while related to different aspects of material and design management within Revit, do not directly allow for the specific adjustments needed for start and end posts. The Material Browser is focused on selecting and managing materials rather than structural elements of railings. Type Properties allows for broader settings adjustments for the type but does not drill down to individual component placements specific to balusters. "Edit Rails (Non-Continuous)" focuses on modifying the rails themselves, rather than managing the balusters or the end posts associated with them.
