ArchiCAD IFC geolocation

From Wiki.OSArch

To meet the MVD requirement, prior to exporting your IFC4 file please setup Archicad as below.

Firstly you will need to locate the 'real world' origin of the project. Open the Project Location dialogue by navigating to Options > Project Preferences > Project Location... completing the following fields:

MVD Variable Project Location Attribute Description
{latitude_longlat} Latitude The latitude of the site
{longitude_longlat} Longitude The longitude of the site
{elevation_number} Altitude (Sea Level) The elevation of the site

Also for the purposes of geolocation exchange, it is necessary to place an Archicad Survey Point object in your project. This should be located at a known point. After placing and while the Survey Point is selected, open the Object Selection Settings dialogue. Under the Survey Point Settings tab, navigate to Geo Referencing Map... and enter corresponding values from the below table.

MVD Variable Survey Point Attribute Description
{coordinate_reference_name} Name The name of the CRS
{description_value} Description The description of the CRS
{geodetic_datum_coordinate_reference_name} Geodetic Datum The geodetic datum of the CRS
{vertical_datum_coordinate_reference_name} Vertical Datum The vertical datum of the CRS
{map_projection_coordinate_reference_name} Map Projection The map projection of the CRS
{map_zone_coordinate_reference_name} Map Zone The map zone of the CRS
{eastings_number} Eastings The eastings of the model must be offset by this value to derive its global coordinates
{northings_number} Northings The northings of the model must be offset by this value to derive its global coordinates
{height_number} Orthogonal Height The height of the model must be offset by this value to derive its global coordinates
{rotation_number} X Axis Abscissa, X Axia Ordinate Using a Polar Coordinate calculator, transform the required project north rotation to 3 o-clock into the X Axis Abscissa and X Axia Ordinate. Clockwise rotation clockwise is negative, anti-clockwise is positive
{scale_number} Scale The model must be scaled along the horizontal axis by value to derive its global coordinates
