What tool can be used. The nose of the arc needs to be at a specific station.en-USTelligent Community 12https://communities.bentley.com/thread/766650?ContentTypeID=1Mon, 22 May 2023 06:49:34 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:42404b1b-ab20-459b-a8d3-c4b40448d99dJohannes Paulus Visagie<p>Thank Lucas for coming back. What I am trying to achieve is to generate a flexible configuration where the rules stay in tacked at any condition. I started with the ideal condition where the offsets are parallel. After creating the rules, I need to edit the base geometry to any condition without losing the design intend. Hope the video provide more clarity.<a href="https://communities.bentley.com/cfs-file/__key/communityserver-discussions-components-files/5922/ORD-Island-Geometry.mp4">communities.bentley.com/.../ORD-Island-Geometry.mp4</a></p><div style="clear:both;"></div>https://communities.bentley.com/thread/766479?ContentTypeID=1Fri, 19 May 2023 13:01:46 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:72f23cba-9617-43eb-8d36-316e8e704b91Lucas Hicks<p>I would use the extend line to pull back the to red lines to an approximate location, do the first close to where you think, when doing the second use the end of the first line as a data point.&nbsp; Then create your arc, you know the radius form the distance between the red lines.&nbsp; Then use the align elements by edge to on the arc.&nbsp; Then use the extend or trim tool on the two red lines.&nbsp; This assumes all 4 lines are parallel.</p><div style="clear:both;"></div>
