Global Variables

Global variables allow you to define constants which are independent of the Argus ONE layers in your project. Global variables can be of type real, integer, boolean and string. They can be accessed from the expression dialog and thus can be introduced into any Argus ONE expression, either into parameter expression or into export expression or variable.

Group Type Layers

Group type layers enable you to organize any number and type of layers into groups. This allows you to hide, show and collapse all layers belonging to a group and thus better control your views. Group type layers have no parameters and can not store data or information of any type.

The Hand Tool

The hand tool enables you to scroll your view in the vertical and horizontal directions simultaneously.

Using the Hand Tool

If you magnify your view to a size larger than the window, you can use the hand tool to move new areas into view.

On-line Help

On-line help is available through the browser of your choice. Whether you use the Help menu, or click the help button in a dialog, your browser will open to present the appropriate section in the on-line help.

Zoom to Fit

The zoom to fit command enables you to set your view so that all objects in your document fit in the current window size.

To Zoom to Fit

• From the Navigation menu select Zoom to Fit.

Not all objects fit in the current window size.
All objects fit in the current window size.

Print Area

The print area option allows you to set an area within your project's drawing size that will print when you issue the print command.
The default print area is set to be identical to the drawing size.

Setting the Print Area

You can set the print area in one of two ways:

• Moving the Tab icons in the horizontal and vertical rulers.
• Using the Set Print Area dialog to define it numerically.

The Print Area rectangle

The vertical Tab icons defining the vertical extent of the print area.           The horizontal Tab icons defining the horizontal extent of the print area.

Select the Show Print Area menu to Show/Hide the print area rectangle. Select the Set Print Area... menu to open the Print Area dialog. Select the Reset Print Area... menu to reset the print area to the drawing size.	Numerically define the extent of the Print Area

Non Uniform Scaling

When you solve a cross-sectional problem, or a problem domain which lies along an elongated strip such as a river, one dimension of the domain would be much larger than the other. Such elongated problems present a visualization problem if the coordinate system is uniformly scaled, that is, when the scale of real world units to screen units is identical in both the X and Y axis.

Non uniform scaling is a very powerful option which enhances the Argus ONE workplace to allow one to design, work and visualize very elongated problem domains. The three Argus ONE meshing modules support this option and automatically create grids and meshes which take into account the non-uniformity of the problem domain while performing auto mesh and grid generation, thus creating elongated blocks and elements.

Scale is set to,1 to 1 and the domain density is set to 0.25.

A domain of 30 units long by 2 units high is automatically grided using the above specified density and scale. The grid might be over discretisized in the X direction. Also viewing the grid using zoom-in is relatively limited because of the exaggerated

Scale is set to,15 (X) to 1 (Y) and the domain density is left at 0.25. When the domain is automatically grided at this scale, the X density (block side length) is reduced by the X scale (~0.25x15), while the Y density remains the same. Two objectives are achieved: 1. The grid is less discretisized in the X direction, and 2. Viewing, zooming and editing is as convenient as working with non-elongated domains.
