https://communities.bentley.com/products/building/performance/f/hevacomp-forum/177974/modelling-of-duct-passing-through-riser-at-45-degreeHI I HAVE A DUCT PASSING VIA RISER FROM L1 TO L6 AT AN ANGLE OF 45 DEGREE OR SAY NOT IN A 90 DEGREE VERTICAL WAY. PLEASE COULD YOU BE SO KIND TO DEMONSTRATE HOW THIS CAN BE MODELED. MANY THANKSen-USTelligent Community 12https://communities.bentley.com/thread/516047?ContentTypeID=1Wed, 10 Apr 2019 12:24:52 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:97fc4b10-b5cb-431f-b636-9166c24ab2dcGL<p>This helps.

You would just need to work out the geometry needed to achieve the required angle.</p> <p>I will try to demonstrate this in a video, more info to follow.</p><div style="clear:both;"></div>
