Building Coordinates and Heights

You can define the site origin coordinates and north direction, and the site, model and building origin locations relative to each other. When you save the model to an IFC file, the coordinates are also written to the IFC file. The coordinates are written to the origin of the plot.

1. Open the building's document browser.
2. Open Settings > Location and height.
3. Double-click Building coordinates.

Define the data in the Building Coordinates and Heights dialog box.

Site location

Coordinate format

Select one of the following as the configuration method:

• ddd.dddd - Decimal degrees, for example 61.45508644° N, 23.85375571° E
• ddd mm.mmmm - Degrees and decimal minutes, for example 61° 27.305186' N, 23° 51.225343' E
• ddd mm ss.ssssss - Degrees, minutes and seconds: 61° 27' 18.311184" N, 23° 51' 13.520569" E

Site origin location

Enter the coordinates in the text fields.

• Site latitude
• Site longitude

Model angle

By default, the model angle is 0, so the y axis of the building model is parallel to the latitude line.

You can set the model angle in either of the following ways:

• In the Deg field, enter the angle measured clockwise from the positive line of latitude.
• Click Locate in model. If the floor plan of the building was active when you selected the function Building coordinates, click two points on the floor plan. If the building model was active when you selected the function, click to two points in the model. You can first set the model to the view you want.

Note: The model angle is not displayed as geometry in the floor plan or model.

Site origin location in Vertex coordinates

Enter the site origin distance (mm) from the model origin in x and y axis directions in the text fields.

• Site location x
• Site location y

You can also click the location of the site origin in the floor plan or in the model by clicking Locate in model. Activate the desired working window before selecting the function Building Coordinates.

Note: When you click the location of the site origin in the model, you also select the distance (mm) of the site origin from the model origin in the z-axis direction.

You can make the site origin visible in the floor plan and model by selecting Site origin visible. Origin marking in the floor plan:

Origin marking in the model:

Distance from sea level

This height information affects the height markings to be added in the building drawings.

Site height from sea level

Enter the height position (A) of the site in relation to the sea level as meters in the Altitude (m) field.

Building height from sea level

Enter one of the following heights. The program calculates the other value.

• Building height from site - Enter the distance (d) of the building origin (0,0,0) in meters from the height of the site (A).
• Building origin from sea - Enter the height (B) of the building origin (0,0,0) in meters relative to sea level.

The building origin height is also used as the base height of a terrain.
