![]() Check this option to correctly load a model that stores coordinates in a left-handed Cartesian system. Load left-handed model as right-handed- Global Mapper recognizes a right-handed Cartesian system for 3D model formats, where the Z axis is positive coming forward. If the model labels the vertical axis as Z, check this option to orient the model correctly. Global Mapper recognized the Y axis as the vertical axis for 3D model formats. Load Z-up model as Y-up - Different 3D model formats label the axes differently. The 3D File Import options dialog will also appear when loading most 3D model formats. The 3D model can also be placed in a location using the Pad Site placement tool. The Planar Units and Elevation Units can also be set to match the model units. If this is not available for the model type, or it is not recognized from the file, manually specify the Central Latitude and Central Longitude in the projection dialog for the orthographic projection to correctly locate the origin of the model in Geographic Coordinates. Some 3D model formats support geo-location of the model, which specifies the Latitude and Longitude location of the origin. Most 3D model formats can be placed with a custom Orthographic Projection, where distance is measured away from the origin of the X,Y and Z axes. To integrate 3D Model formats with other spatial data, the projection and model orientation and units must be specified.
