How to set unit when using IImport3DFile?

Discussion created by swdmike on Jun 26, 2011
I use IImport3DFile to import a skp file into ArcGlobe, but there is a error. ArcGlobe cannot understand the unit of my model. The model file's unit is in meter,but ArcGlobe is in degree.

Is there a method to transform the unit?
