At any time, only one color group of the Navigation Tree is active, where all the newly drawn objects are placed and listed. [[CubeCAD]] displays the active color's name in bold. When you start [[EM.Cube]] for the first time and draw a new object in [[CubeCAD]], a default color named "Color_1" is immediately created and set as the active color. Every time you create a new color, it is set as the active color. To change the active color, right click on the name of a color and select '''Activate''' from the contextual menu. New objects will now be added under the new active color.
To draw an object in [[EM.Cube]], click one of the many '''Object''' buttons in '''Object Toolbar''' and start drawing a new object in the project workspace. Alternatively, you can call on any object creation tool through one of '''Menu > Object > Solids''', '''Surfaces''' or '''Curves''' submenus. Once an object creation tool is selected, the shape of the cursor changes to a cross, signifying that [[EM.Cube]] is in object creation mode. Left click anywhere in the Main Window to draw an object of the selected type. While the new object is being drawn, a property dialog appears on the lower right corner of the screen. Also, a small '''Help Tip''' window opens up on the upper right corner of the screen that guides you through the drawing process. The property dialog allows you to customize the new object's dimensions and other [[parameters]]. The entered values for lengths are always in the currently selected project units and angles are measured in degrees.
