[OR 10.10] An tip on creating geometry arcs between corridor elements independent from corridor

Question

Hello,

I'm looking for a quick tip on creating geometry arcs for point control between corridor elements. For example like in the picture between existing circle and road lane. Creating any type of arc using the elements descending from corridor creates a recursive solution. I was wondering if there's a way to use the corridor elements but avoid "dependency". I have ways but they seem more or less inaccurate and really inefficient when there's everything I need right in front of me.

Reinis, 
 As far as I know, there are only two options to achieve what you're looking for. 
 
 You can create geometry elements that model the exact dimensions of the corridor, but they can not in any way be related to the corridor to avoid dependency. From there you can create any arc or other element and use that as point control. 
 Create the arc you want between the corridor elements in a separate file, using the corridor file as reference. Detach the reference containing the corridor, this will break the dependency. It will also remove the design intent rules, making the arc a fixed element that will not change when the corridor changes. Use the arc as point control. 
 
 Personally I suggest using option 1, because that will keep the design dynamic, even when you have to manually change the base geometry to mimic the corridor.
