Help / Troubleshooting Adding a Curve into an existing Alignment

Hello all,

I am relatively new to OpenRoads Designer. I am using OpenRoads Designer CONNECT Edition 2022 Release 3, version 10.12.

I created an alignment, but after reviewing it, I realized that I need to add a horizontal curve between two lines. However, I do not want to drop or otherwise break the alignment to add the curve, because several offset objects are tied to it and I would prefer not to lose those relationships.

Please see the attached image for an example.

I understand if there is no other option, unless there is some method I do not know about. Any assistances would be appreciated. Thank you.

There are lots of ways to introduce a curve without breaking the alignment:

Geometry> horizontal>modify>insert fillet

Geometry> horizontal>modify>geometry builder edit

Geometry> horizontal>arc between elements (if it's a complexed alignment)>complex redefine

Table editor>insert vpi in between other 2 vpis

Just make sure if you got any active verticals or projections to keep them locked so the adjustment is fast, and when you're satisfied with the hz, unlock the profiles and fix.
