Stairs disappear in the Layout Book

[Martin Jules]

Some stairs appear correctly in the View Map but are missing from the Layout Book. What could be causing this issue?

Operating system used: Windows

It's a bug! Just copy and paste the stairs into a new file, then copy and paste them back into the original file.

In the file where it does not appear on the Layout, is your project located far from the Project Origin? That is one factor that may cause elements to not appear on Layouts.

No.
