<b>EM.CUBE</b> to start the program. By default, EM.Cube opens up a blank project with the name “UntitledProj1” in

its [[CubeCAD]] Module.

You can start drawing objects and build up your physical structure right away. Or you can initiate a new

the menu <b>File &rarr; New Project…</b>). This opens up the New Project Dialog, where you can enter a title for your

new project and set its path. You can use the Windows Explorer to go to the desired folder where you want to

CAD operations by themselves. Therefore, you can build a new project from the ground up in any of EM.Cube’s

computational modules.

Before you begin to set up the geometry of your project, let’s quickly ensure that the project units are set up correctly. First, open up the Units Dialog box by selecting the <b>Units</b> button of the Simulate Toolbar (or using the keyboard shortcut <b>Ctrl+U</b>). Make sure the length units are Millimeters, and select <b>OK</b> to continue. Similarly, for frequency and bandwidth, select the <b>Frequency</b> [[Image:fdtd_frequencyb2.png]] button of the Simulate Toolbar (or use the keyboard shortcut <b>Ctrl+F</b>) to open the Frequency Dialog box. Make sure both the frequency and bandwidth are 1GHz, and select OK to continue.

The default view in EM.Cube is a 3D Perspective view of the project workspace. A different view can be selected by one of the 7 window selection buttons on the View Toolbar. Further, the 3D window can be split into the Top, Front, Right, and Perspective viewports by clicking on the “Split Viewport” button. This will display four smaller windows simultaneously, allowing you to view your structure from each of these four angles at once. Clicking the “Merge Viewport” button, right next to the “Split Viewport” button, brings the split view back into a single view.
