Please note that external CAD objects are always imported to [[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD]] [[Image:cubecadlogo.png]] first. From CubeCAD you can transfer all or some of the imported object to any of the other computational modules. For this lesson, first create an impenetrable surface group called Block_1 in [[EM.Terrano]]'s navigation tree with all the default settings. This means that your buildings will have the default dark brown color and their material composition would be "Brick" with ε<sub>r</sub> = 4.4 and σ = 0.001S/m.
To import the building models, go to the File Menu and select <b>Import...</b>. The standard Windows Open Dialog opens up with the file type set to <b>.STPSTL</b>. Browse your folders to find the downloaded "Ann_ArborAnnArborDowntown.STPSTL" file. A total 83 solid objects appear in the project workspace of the CubeCAD Module as shown in the figure below.

Next, you have to move all the imported buildings to the Block_1 group of the [[EM.Terrano]]. To do so, select all the building names on the navigation tree: Default. Start with Right-click on the selection and select '''Move To → [[EM.Terrano]] → Block_1''' from the contextual menu. All the objects will disappear from CubeCAD and will reappear in [[EM.Terrano]]'s navigation tree under the "Block_1" group. If the imported building model contains many solid objects, <bi>Solid_1e.g.</bi> , Solid_1, Solid_2, …. Solid_n, in order to move all the imported buildings to the Block_1 group of the [[EM.Terrano]], select all the building names on the navigation tree. Start with Solid_1 and select it. Then hold down the keyboard's {{key|Shift}} key and click <b>Solid_83</b>Solid_n. While still holding down the shift key, right-click on the selection and select '''Move To → [[EM.Terrano]] → Block_1''' from the contextual menu. All the objects will disappear from CubeCAD and will reappear in [[EM.Terrano]]'s navigation tree under the "Block_1" group.
