The rooms will all remain, and the background will be updated.&nbsp;You can then alter rooms as desired. Please see<a href="/products/building/performance/w/building_performance__wiki/31829/dxf-import---changing-a-dxf-drawing"> this article </a>for further info.</p> <p>If you wish to delete the floor, the roof will remain but you will need to &#39;Set Up Roofs&#39; once more after entering your rooms.</p><div style="clear:both;"></div>
