Govardhan,

 

From the FME Desktop Readers & Writers documentation for ESRI FILE GDB http://docs.safe.com/fme/html/FME_ReadersWriters/Default.htm#geodatabase/Multipatch.htm

 

 

 

Multipatch

 

geodb_type: geodb_multipatch

 

 

 

Features with this value consist of a 3D geometry, used to represent the outer surface of features which occupy a discrete area or volume in three-dimensional space. Geodatabases directly support 3D polygonal faces, triangle fans, triangle patches and triangle strips. By definition, the surfaces which compose a multipatch do not need to be connected. This value is used by both the reader and the writer.

 

 

 

Multipatches support appearances, but only one appearance per surface is supported. For two-sided surfaces, the writer will favor non-default appearances with textures, with the front side taking precedence over the back side. If this behavior is not desired, the writer can be forced to choose the front side by using the AppearanceRemover transformer in FME Workbench to remove all back appearances.

 

 

 

For writing, all 3D geometry types are supported. Any types of 3D geometry which are not directly supported in a geodatabase (e.g., solids) are decomposed into a set of 3D polygonal faces prior to writing.

 

 

 

Have you tried using the AppearanceSetter transformer when writing from Collada to File GDB feature class?

 

 

 

Happy FME-ing :-)

 

 

Cheers

 

SRG
