In the model file naming convention, what comes last just before the file extension?

The last piece before the file extension in a model file name is the sheet sequence number. This position is chosen because it encodes the page order within a set of drawings, so when you sort files by name, the sheets appear in their proper sequence. The actual file type is indicated by the extension itself (for example, .rvt or .dwg), not by a separate trailing segment. The project code and discipline designator are usually placed earlier in the name to categorize and identify the file, but they don’t sit at the very end. The sheet sequence number is specifically the final naming element before the extension, making it the last thing you see in the base name.
