EM[[Image:fdtd_lec1_3_newproject.png|500px|left]] M.Cube’s [[CubeCAD]] Module lets you construct 3D geometries, or import them via external model files
such as *.stp, *igs, or *.stl. Once these geometries have been modified or completed, they can be moved to
other modules within EM.Cube for further simulation. On the other hand, all modules of EM.Cube offer full
[[Image:fdtd_lec1_3_newproject.png|500px|left]] 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.
