Measuring Systems: Imperial, SoftMetric and European Metric.

Double-click on the icon named RebarWin to start the application.

When you start the application for the first time, the Measuring System window shows up. You can call this window later at any time by choosing menu option General->Measuring Units, Weights and Bending Gains. Here you can choose which of the three (Imperial, SoftMetric or European Metric) is going to be the default measuring system, decide format and number of decimal places of the measuring units, setup weight/length ratios and bending gains for each bar size.

You can use a different measuring system in each project. When you start a new project, you choose which of the three measuring system you are going to use in its orders, and the one you choose as default in this Measuring System window will be the preselected one.

Here is an explanation of the three systems:

 

IMPERIAL SYSTEM: Bar lengths are expressed in inches or feet. Weights are expressed in pounds. The initial bar sizes ( which you can change, delete or add to ) when the program is installed are:

Bar Size

Diameter (inch.)

Weight lb/ft

SOFT METRIC SYSTEM: The default bar length unit for this system is millimetres. You can easily choose centimetres or metres instead by pressing the Soft Metric System Setup button. Weights are expressed in kilograms. The initial bar sizes ( which you can change, delete or add to ) when the program is installed are:

EUROPEAN METRIC SYSTEM: The default bar length unit for this system is centimeters. You can easily choose millimeters or meters instead by pressing the European Metric System Setup button. Weights are expressed in kilograms. The initial bar sizes ( which you can change, delete or add to ) when the program is installed are:

To adapt the measuring system(s) you are going to use to your needs press its setup button. Press one of the following buttons: Imperial System Setup, SoftMetric System Setup or European Metric System Setup.

Here is the Imperial System Setup window. Those for the other two systems are similar.

In this window you can choose the format for the bending length and total bar length measuring units. In the case of the Imperial System you can choose from:

You can also decide the number of decimal places for weight (lb.) and angles (degrees).

In the case of the SoftMetric and European Metric systems the available formats for the bending length and total bar length measuring units are:

You can also decide the number of decimal places for weight (kg.) and angles (degrees).

Please be aware that changes made here regarding measuring units, rounding and decimal places will only be reflected when you create a new project. When you create a new project, you choose which of the three measuring system you are going to use in this project, and the format and number of decimal places are taken from this setup, and will be kept throughout the duration of the project. Changes of format or number of decimal places here will only affect new projects which choose this Measuring System.

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.

Let's go on. Now press the continue setup button and you will be able to change the bar sizes properties (diameter, weight and bending gains). You can also delete or add new bar sizes. To add a new bar size choose Edit->Add Row, and to delete one choose Edit->Delete Row. The sequence of the rows has no importance.

In the first column you can type the machine number and, in doing so, the weight and bending gain settings in this row will only apply to bars of the machine and bar size indicated. So you can have a different setting for each machine. You can also leave it empty, and the settings will apply to all bars of the indicated bar size, regardless of the machine. You should only inform the machine column if you intend to apply different weight/length ratios, bending gains or hooks depending on the machine. Of course in this case you should fill many more rows, one with the setting of each machine-bar size combination.

Here is the window for the Imperial System:

Here is the window for the SoftMetric System:

And here is the window for the European Metric System. In this system the diameter is the same as the bar size:

You can inform the bending gains for the following angles: 15, 30, 45, 60, 75, 90, 115, 130, 145, 150, 165, 180, 270, 360. Bending gains for other angles will be calculated from these values. For instance the bending gain for 50 will be calculated from that of 45 and 60.

The column ARC360 is the bending deduction applied to a 360 arc. This means for instance, that if the arc is 90, only one fourth of the deduction in that column will apply. If the arc is 180, one half of the deduction in that column will apply. Initially, as you see this column is empty. So if you want deduction to be applied to arcs you must fill this column.

In the last columns you can change the default hook values for each bar size. The column captions are:

When you have finished, choose File->Save and Exit.

You are again in the measuring system window. You can now setup another measuring system if you are going to use more than one or press the Exit Setup button.
