To create floor plan drawings that can be imported into VertiGIS FM, you must have access to and know how to create drawings using a CAD and drafting software application (for example, AutoCAD). Instructions for how to use CAD software applications is outside the scope of these guidelines.
The guidelines below must be followed for any floor plan drawings imported into VertiGIS FM.
•Drawing files must be saved as DXF 2000 files or older.
•File names for drawings must not include any special characters.
•Drawings must be able to be opened using a standard CAD program without error messages or warnings.
•Drawings must use the World Coordinate System (x, y, z).
•The unit used by the drawings must be set to metres.
•All displayed objects must fall within the coordinate range of -2000,-2000 to 2000,2000.
•Drawings must be created and saved in the model area. Views must be removed before you import the drawing into VertiGIS FM.
•Drawings must be created in a 2D format. Therefore, if creating plans with 3D applications, you must ensure that Z values are always 0.00. Minimal deviations (e.g., 000001) will cause an error when you import the drawing.
Individual layers must only contain objects of one type. For example, lines and polylines cannot be combined within a layer.
Default layers are outlined below. Settings for these default layers, including their names, can be changed under DXF Layer in CAD Administration.
This default layer contains only room polygons. Islands are not supported and must be replaced by bars (for example, if the room contains supports). The layer cannot contain any other elements (for example, lines).
Room polygons are closed polylines. In AutoCAD, use the LWPOLYLINE command. The polyline has a closed property and a z-value of 0.00.
The room polygon represents the boundary of the room. If you want to show rooms with curves, these must be recorded accordingly.
This is the default room stamp contained in each room polygon. No other elements can be used in this layer.
Fixed attribute names are used to assign data to the room. These two basic text attributes for space stamps must be present:
•ROOM
•DESIGNATION
The ROOM attribute contains the room number and, as a unique key, can only be assigned once per drawing. The DESIGNATION attribute can be empty or assigned more than once per drawing.
If the room designation is not filled, it will automatically be equated with the room number during the import.
All room data can be imported from the drawing, including the following:
•SURFACE
•SCOPE
•DIN 277
•USE BY GIF
•DIN277_USE
•MAX. OCCUPANCY
•NET AREA MEASUREMENTS
•RENTAL AREA
•ROOM HEIGHT
•PERMITTED TRAFFIC LOAD
•REMARK
•NUMBER OF RADIATORS
•FLOORING
•LIGHTING
•SUN PROTECTION
•AIR CONDITIONING
•BLACKOUT
The area and the perimeter can be imported, but they do not have to be. These measurements are calculated using the spatial polygon during the import.
The room stamp is a block reference that only consists of the attributes above. No other elements may be included. Each room stamp is assigned to exactly one polygon. The insertion point of the stamp is always within the polygon. The room stamp must have the z-value 0.00.
ACAD_Floor is the default layer for the story polygon. This layer contains one polyline without a stamp.
In VertiGIS FM, the gross floor area for a floor is calculated from the polygon.
You can create custom layers if required. Custom layers can only contain objects of the same type. For example, lines and polylines cannot be combined within a layer.

These objects can be imported directly without resolution. The viewer displays these objects in their colors and line widths as created in the drawing. Special line types (e.g. dashed) are only implemented approximately. Therefore, there may be a different view in the viewer.
