Schematic is a diagramming tool that allows complex diagrams to be drawn with ease. Schematic allows you to combine text, pictures, shapes and connectors to create clear and informative diagrams. Schematic includes intelligent connectors that link graphical objects and includes lUML, electrical, network, flowchart, DFD, ERD libraries. Users can easily create their own object libraries. Supports export of diagrams as EMF, PNG and JPG files.

Grab It! is a Microsoft Excel based utility that digitizes graphs or charts to obtain the original data. Data can be log, linear, date, or time and can have multiple data sets. Contains a measurement function to measure from point to point on a scaled picture (micrograph, map, schematic). Output is displayed real-time directly in Excel for easy re-use. Free software upgrades forever!
