Layers

[Mike Missimer]

Good morning

I have a basic question about layers in a pdf.  Some pdf's allow you to see layers and others do not.  Is this related to how the pdf was originally created?  Is there a way to see layers in all p

Is this about Acrobat or Reader or some other Adobe program used to create a PDF?

Only some PDF files have layers.

This is on Adobe Acrobat DC

Post follow-ups under your original question, and don't post your private details.

The PDF needs to be created with layers. With some PDF files it is quite interesting to have layers like geo-data or technical drawings. It's the creator ('s software) who decides if layers are in the PDF or not.

By seeing layers, do you mean the "layers" listed in the Layers Panel on the left side of the Acrobat Window? This window is used to set layer visibility and other properties. 

There is an internal PDF setting that determines whether or not a "layer" is listed in this panel. This setting is not available in the Acrobat UI, but it can be controlled with JavaScript. 

You'll find more info in this article:

Can you be more specific "in all programs" you are thinking?
