The Export Collada (DAE) Command is accessible from either the File > Export Vector Data or the File > Export 3D Data options. This export allows you to export loaded mesh and area features to DAE format.
3D File Export Options
Specify the axis orientation to use in the export. Global Mapper labels the vertical axis as Z, but in some 3D formats the vertical axis is designed as the Y-axis. Check the Export model as Y-up option to use the Y-up axis orientation.
3D Mesh features do not support cropping within mesh objects. With a specified export bounds, mesh features inside the export bounds will be exported, uncropped. Mesh features with no part inside the export bound will not be included in the export.
For more information on the bounds specification options see Export Bounds.
