Zooming in shows that the grid doesn&rsquo;t seem to always line up with the connection point of the emitters, as i&rsquo;ve modelled some of them at 45 degrees (see figure below) I&rsquo;ve tried checking this in the isometric view however due to the large building it is quite difficult to check. Is it ok to model the emitters at 45 degrees? And is there a way to check whether they are connected?&nbsp;</p> <p><img src="/resized-image/__size/960x720/__key/communityserver-discussions-components-files/275871/FF913A46_2D00_F463_2D00_48DE_2D00_B2B1_2D00_09A5529DD7A5.jpeg" alt=" " /></p> <p>My other question is regarding the system marker. Do I need to place it on the flow or return? Or do i need a single flow &amp; return pipe?&nbsp;</p> <p>Thank you in advance&nbsp;</p> <p>Seb</p><div style="clear:both;"></div>https://communities.bentley.com/achievements/460ac7df-7ccc-4c42-a204-9e05eef3be09Sun, 14 Aug 2022 00:57:00 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:cd914b63-3b1e-4747-911d-60073b39e4f4Ask a question in a forum.
