no2,

Attached you will find two files:
- your house with roof and windows
- the roof with windows, before using export/import (see tutorial).

To make such a roof, and make sure it fits nicely on the house, it's wise to give your walls exact X,Y coordinates. Mouse-drawn coordinates are not very precise, and therefor it will be difficult to make a roof that fits well.

Study the files, and let me know if this is what you wanted.
