**3.1 Creating a new building project**

As shown in **Figure 2**, a new building project named "Sample Housing Project" was created by clicking the New sub-menu under the File menu in ArchiCAD. The default template set was selected for the template option of the new building project in ArchiCAD. First, the working unit settings were set in the sample housing project. "1/ 50" for the scale unit, "cm" for the length measurement unit, "m2" for the area measurement unit, and "m3" for the volume measurement unit was selected in the working unit settings in ArchiCAD. After the working unit settings were set, the sample housing project's floor information was named respectively -1. Floor, 0. Ground Floor, 1. Floor, 2. Floor, 3. Floor, 4. Floor, 5. Floor, 6.
