Kubla Cubed has extensive tools for importing site plans into your projects. A number of different file formats are supported (.pdf, .jpg, .bmp, .tiff). You can import as many site plans as you need, switching them on and off when you need to view them.
Being able to display multiple site plans makes it much easier to complete a take-off if you have your existing and proposed elevation data on two separate drawings. You can also use the crop, move, and align tools to 'stitch' drawings together in situations where a single site plan is spread across separate pages of a document.
