PlotCalc is a program that extends the functionality of CorelDraw application for working with plotter. After installing PlotCalc in CorelDraw, there is an additional toolbar that allows you to work with cutting layouts. With PlotCalc you can quickly select film waste, save raw materials by placing graphic elements on the film more compactly and calculate the total length of the curves to calculate the cost of cutting. The project is then prepared for cutting (to turn shapes into curves, and to remove fillings, among other things). The PlotCalc function enables you to layout an entire sheet using the A4 format. Using the program, a user may determine the cutting angle on a plotter knife, select the priority of vertical or horizontal movement of the plotter knife, use a test mode, etc.
