insert pdf and make it transparent

[KathleenWallis]

I used to do this years ago and cannot remember how. I have parcel maps and I want to insert them into my ArcMap and set the
transparency to about 50% percent. I can insert the map as a pdf or a jpeg, but how to I make it a little transparent so I can see
the orthophoto behind the pdf. I want to use the pdf as rough guide as I digitize over it.
Thanks
Katy

Hi Kathleen,

It sounds like you are digitizing plats over some aerial imagery. There are several ways to import the image from the pdf, but what I would suggest is saving the plat as an image, such as a .tiff or .jpg,  once you have it saved in this format, which is essentially a raster, you can use the add data tool to import into your .mxd, then use the georeferencing tools to rectify the image to the ortho-imagery.
