I have an office floor plan that was given to me in PDF.  I have Acrobat 7.  I would like to be able to color shade certain rooms - but in a transparent way so that I can still see th writing underneath.  Can I do that somehow?  Big Thanks!

Whilst Acrobat 7 gives you some great options, this is not the best tool for doing such task. Adobe Illustrator would be more appropriate if you have it to hand...

There is a way however and that is using the Tools|Commenting Markup from the menu and selecting the 'Rectangle' tool. Draw the shape you need and right click to select 'Properties'. Now you can set fill colour (default:none) and the opacity.

You will have to position these very exactly though, as the transparent boxes when overlap show accumulated transparency, i.e. 2x 33% result in 66% where they meet.

Hope this helps.

Thanks- That does help.  Are the directions that simple for Illustrator too?

Illustrator is a fully fledged drawing program, which has simple functions that work similarly. But you also have the ability to draw custom shapes, which makes the sketching of areas and even the redrawing of your floorplan much easier.

It is worth investing in if you have to do this often. It support PDF import and SaveAs PDF so it is the perfect tool for PDF manipulation.

The application is quite complex so you will need some patience getting used to all the options, but have a look at the help file for custom shapes amd fills then you are off to a good start.

Also familiarise yourself with keyboard shortcuts such as holding down shift key for drawing or moving in a straight line and you can draw in no time.

All the best
