Walls show on sheet but disappear on print

[Anonymous]

I've started a new contract and have taken over a lot of pre-existing models. The model I am working on is in Revit 2018 and I've noticed that the internal walls don't show unless the view is set to Wireframe. This isn't really a problem but when I print or print preview, the walls show initially as it's loading but then disappear when fully loaded and they don't show on the PDF/print.

I've checked view template settings and walls are turned on in both my model and the linked model and I've tried printing to Raster instead of Vector but it made no difference.

Does anyone have any ideas?

Many thanks,

Look like you are working in a reflected ceiling view, have your checked you underlay settings ?

-Check the View Range/cut plane.

-Check Worksets

-Check View Filters

-Check Phasing/Phase Filter of View

-Check if any Design Options

-Check visibility of Linked models

-Check if there could be a masking region, or even a Floor could be obscuring the view.

Do you have a custom view crop region?

...Replace Halftones with Thin Lines (under print setup)?
