Point transformation from Local to Global WCS

Hi,

I'm trying to transform a point3d information from a JT component inside JT assembly.
The point is based on the WCS of that particular component.
I need to transform this point to the WCS of the whole assembly.

The code showed in the links below are not working.

I'm using C# for performing this operation.
Kindly help me on this.

Thanks
