Once i finished, it turned it into a complex geometry by &quot;Complex by Element&quot;. But now i need to remove one of these circular curves and replace it with spiral curve-circular curve-spiral curveen-USTelligent Community 12https://communities.bentley.com/thread/579821?ContentTypeID=1Sun, 12 Apr 2020 14:19:31 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:2a6464db-2b42-4a83-a7d6-cdcc7d06ec81Engineer Yok<p>Thank you very much!</p><div style="clear:both;"></div>https://communities.bentley.com/thread/579789?ContentTypeID=1Sat, 11 Apr 2020 16:31:35 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:1822895b-66dd-4287-a98d-2258af424d33The Zen Dude<p>Select the alignment and go to the <strong>Properties</strong>. At the top of the <strong>Properties</strong> dialog you can expand the <strong>Complex Elements</strong>. Find the curve in that geometry tree ... it will probably be listed as a <strong>Fillet</strong> between the two <strong>Lines</strong>. If you select that Fillet the Properties will open up below. Find the <strong>Back</strong> and A<strong>head Transitions</strong>&nbsp;(those are the spirals) and change the <strong>Type</strong> from <strong>None</strong> to <strong>Spiral</strong> and add your spiral criteria right there.</p> <p><img alt=" " src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5922/0143.jpg" /></p> <p><img alt=" " src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5922/3757.jpg" /></p><div style="clear:both;"></div>
