![]() The keyboard pops up for you to type something, and then you are done. Just tap a point on the image, keep your finger on the screen as you drag, and then release your finger where you want the callout text to go. This is easy to do with the new callout tool. Often, when I'm working with an exhibit, I will want to draw a line to something important and then say something in the margins about what it is or why it is important. And you can even create a cloud shape to draw more attention to an area. You can fill your shapes with colors or hash patterns and you can change the border type and size. With the new polygon and polyline tools, you can create countless different shapes with straight edges. PDF Expert already had tools that you could use to create rectangles, circles, lines, and arrows. But I've had many times during litigation when I needed to estimate the length of a wall or the area of a room or a warehouse or a parking lot and this is a tool that help to perform some quick-and-dirty calculations. ![]() Obviously, you cannot count on these measurements to be exact, although I suspect that with high-resolution PDF files that are drawn exactly to scale, you might be able to get pretty close. For example, in the following image, I compare the area of the floor portion of the Senate Chamber to the Hall of the House of Representatives. You can also calculate the area by selecting three or more points. Capitol visitor center, the actual diameter is 96" so that is a pretty good guess just based on this image. Using the measure tool, the app estimates that the diameter of the Great Rotunda is 96" 1.5" - and according to the U.S. Capitol, which has a scale at the bottom. For example, here is a public domain floor plan of the U.S. Once you have set the scale, you can then use the distance tool to measure the distance between any two points. And for some images for there is a scale, PDF Expert will intelligently detect the scale. ![]() Use the new Calibrate tool to put a point at both ends and then tell the app what that distance represents. Or perhaps the drawing has a scale at the bottom. Perhaps the drawing already tells you in feet and inches the length of a wall or something like that. Start by finding two points in the drawing for which you already know the distance. Any time that you are working with a drawing that has a scale, PDF Expert can now perform measurements. The first new set of tools are useful for determining rough measurements. You need to pay for a PDF Expert PRO subscription to get access to these tools ($50/year), but I already considered that a bargain for my law practice for reasons that I have previously described, and now the subscription is even more valuable. And while I'm sure that these tools would be useful for contractors and architects, I can see lots of uses for these tools whenever an attorney works with floor plans, schematics, designs, aerial photographs, and many other exhibits. PDF Expert, my go-to app for working with PDF files on my iPad, was updated to add what the developer Readdle is calling construction tools.
