You can create a new project by choosing General->Project->New Project.
You can update or delete an existing project by choosing:
General->Project->Update / Delete Project
When you create a new project, you choose one of the three Measuring Systems (Imperial, SoftMetric or European Metric). This can't be changed later. The format and number of decimal places are taken from the Measuring System setup (at menu option "General->Measuring Units, weights and bending gains") when the project is created, and will be kept throughout the duration of the project. Changes of format or number of decimal places in this menu option (General->Measuring Units...) will only affect new projects.
However changes in weight/length ratios and bending gains will immediately affect all new orders from either new or already existing projects. If you choose "Order->Update/Delete/Print order", type the code of an old order and print the bar list or labels, the new configuration will also be taken, but if you want the changes to be reflected on statistics like "Order->Order List" you should save the order by choosing "File->Save Order and Exit". Whenever an old order is saved with this option, its weight and bending gains are recalculated according to the current values in the Measuring System setup.
To exit the program choose File->Exit.
