Hi, I am using a trial version of Adobe Acrobat X Pro, with a view to purchasing the program for several members of staff. However, it does not seem to be able to do something fairly simple which I need.. unless someone can help please! I work with maps that come to me as pdfs, and I need to be able to add text items (with arrows) to these maps that are then visible only when certain layers are selected in the new pdf, so that the three sub-contractors I distribute our completed maps to can view either all the text/arrows we have added, or only the info relevant to them if they prefer.
 
We've tried saving three maps each with different info on then importing them as three new layers to the original map, but that doesn't give the functionality to interchange views and it's very time-consuming. We've tried using InDesign on trial version but the layers are messy in the exported pdf (adds obsolete layers as a 'feature', an administrator in an InDesign forum said). I've experimented with the pre-flight functions in Acrobat Pro but found them not so user-friendly. Maybe there is a way to select some text items and export them to a tiff with transparent background, then import these back in as a new layer perhaps? Or please someone tell me I'm being stupid and this was addressed in a simple function since Acrobat v2?!

My Product Information:
Acrobat Pro 10.0, Windows

To change the visible layer you can create a form field, like a drop-down box. One of the built-in actions is "Set layer visibility" which allows you to select which layers to show and which to hide based on the user's selection.
Since form fields are not bound to a specific layer, this drop-down will always be visible.

Hi try67 and many thanks for your response. I've been experimenting with what you have suggested, but it doeesn't seem to work unfortunately. Set layer visibility is only an action that can be requested on mouse up, down etc, which doesn't help me assign text boxes to certain layers that are then easily selectable by my customers - or am I misunderstanding? Also I'm unclear whether you are suggesting I need to create the layers first before turning text boxes to fields, if so do I just import layers as blank documents, how best done? Perhaps my suggestion is easiest about exporting the text boxes from Acrobat into a tiff with a transparent background, then importing this tiff as a new layer, that would solve the prob if anyone knows how to export to a tiff with blank background? Or to import then change the background?!

Paul, can I suggest using the commenting tools? You could add the text items with the arrows and assign each (layer) as a reviewer. This would also provide you with a lot of flexibility since the commenting tools are extensive.
You can then choose to see one set of comment at a time or all at once.

Sounds simple, but I thought it might be a solution for you.

Acrobat can't create comments (annotations) on OCG layers; by default all annotations exist in a "level" above the entire document and so are unaffected by any change in OCG visibility, and everything Acrobat's UI tools can draw on a page will be placed in the base (non-OCG) level. Acrobat is not like Photoshop - just because a layer is selected doesn't mean you're writing on it.

You can move annotations to an OCG *after* they have been created (using Preflight) but it's a complex process, and you can't use the author or content of the annotation to decide where it's going.
