Hello Roopa A,
Archieve.3d.net is not a BIM platform.
You are able to find some gsm but not lcf files.
LCF are contener files which could include texture but not into a gsm file.
So you must rebuild you surface into archicad with internal engine and maxon engine.
IG is not able to delete texture into your BimX.
Have a nice day,
