The "Transforms" group of functions are located in the top right of the display. They provide the ability to zoom into and out of the grid, and rotate and translate the grid in the X and Y axes.

The screen shot below shows a "Ground-Wall" grid with the default transform functions applied.

The "Zoom" transform allows the user to zoom into and out of the grid. The "Zoom" transform is also used to scale the picture size during export to pdf or postscript files. The screen shot below shows the updated grid after the "Zoom" is adjusted to 1.6.

The screen shot below illustrates the grid position after the horizontal roller has been moved towards the left. The grid is rotated around the Y axis.

The screen below illustrates a further transformation of the grid by moving the vertical roller and slider up. The slider moves the grid down in the viewing window and the roller moves the grid in the X axis. The translation sliders are particularly useful when the user has set the zoom to a high value for detailed viewing of the output and the desired part of the grid is not displayed.
