Separate an object in new groups?

Hello Blenderfriends!
I am a new Blender user…I have imported an OBJ-file (a house drawn in Google Sketchup) into Blender. Now i will work with the surfaces on diferent
part of the house, but the house appears in one objekt.

How to do? Can i ungroup it and make new groups?


if you selct a part of it in editmode and press “p” it will separate the selected faces into another object. Hope this answers your question:)

Thank you neighbour!!! You solved my problem…=)
