==Operational Modes of CubeCAD Tools==
Each of [[CubeCAD]] tools performs a certain operation or transformation on one or more selected CAD objects. [[EM.Cube]] provides a number of different ways to use these tools. First, you have to activate a CAD tool. Each tool has a button with a particular icon on '''Tools Toolbar''', which you can click to activate. If you hover your mouse on one of these buttons before clicking, a small tooltip shows up displaying the name of that tool. You can also enable a tool from '''Tools Menu''' at the top of the screen. Many tools have a keyboard shortcut, which you simply type on your keyboard to enable that tool. You can also access some tools from the contextual menu of individual objects either by right-clicking on the surface of an object in the project workspace or by right-clicking on the object's name in the navigation tree. When you access a CAD tool from Tools Toolbar or Tools Menu, one or more '''Help Tips''' appear on the upper right corner of the screen, which guide you along the different steps of usage of the enabled tool.
The first step in using each CAD tool is to select one or more objects. When you activate a tool from Tools Toolbar or Tools Menu, a help tip prompts you to select an object by clicking on it. If the enabled tool allows the selection of more than one object (e.g. Group Tool), you can select the objects one by one and then press the '''Enter Key''' to finish the object selection. At this point, another help tip instructs you to take the next action. For most tools, alternatively, you can first select the object(s) and then activate the tool in one of the ways mentioned earlier. This is often more convenient and spares a few mouse clicks.
