I&#39;m not sure why they are offered as an option, but there is no way to edit them. With regards drawing pipes into the header, the best method is to place the header, attach your incoming pipe to the centre. &nbsp;When drawing the outgoing pipes, start at the header. It may help to zoom in a little. You should try and draw from close to the centre of the header. If your pipe connects correctly the start point will be highlighted with a green circle. a light green circle indicates snapping to another pipe rather then the header and a black circle indicates no connection.</p> <p><a href="/cfs-file/__key/communityserver-discussions-components-files/275871/header.jpg"><img alt=" " src="/resized-image/__size/940x0/__key/communityserver-discussions-components-files/275871/header.jpg" /></a><br /><br />(Note: This information is also referenced in the <a href="/products/building/performance/w/building_performance__wiki/22444.netsys-faq">Netsys general FAQ</a>)</p> <p>Regards,</p><div style="clear:both;"></div>
