### Output Details and Examples

The DXF output report file is formatted according to the “Data Exchange Format” standard rules for representing CADD type coordinates. The file can be used in several inexpensive, shareware or freeware viewers. Quickview PlusTM can display DXF files as shown in Figure 1 below. A free program originally from AutocadTM, Voloview ExpressTM, can display solid model rendering as shown in Figure 2. Other viewers are available from MicrostationTM, VisioTM and other shareware or freeware vendors.

This file is generated when the following line is included in the IDF.

Output:Surfaces:Drawing, DXF;

You can ask it to triangulate surfaces with >4 sides:

Output:Surfaces:Drawing, DXF, Triangulate3dface;

In addition to the building shape (including detached shading elements), the DXF view includes a “true north” arrow (at ground level) and the name from the BUILDING object.

Even in the Quick View version, you can see that the different building elements have different colors. These are the “original” colors used in EnergyPlus. The current default color scheme is shown in the following figure of the solid model.

The DXF file of itself is an ASCII file, with a specific structure as specified in the standard. An excerpt of the file is shown below:
