Would you like this command without the offset ?
Remember that you can customize commands so that it will open with your own setting. I didn't find yet how to Save As to create a new command.it is easy and fast. Just a right click on the dialog.
Your settings, or last used command settings, are saved here for 2022R1: C:\Users\<user name>\AppData\Local\Bentley\OpenRailDesigner\10.0.0_1\prefs\civil_commands
The file for this command is GEOMETRY SPIRAL PLACE BETWEENELEMENTS.xml
You can keep a safe copy if you want to distribute. I would not recommend to manually edit the XMLs.Of course it applies for many civil commands.
Some will try to also set solution to 1. But unfortunately the solution that is the one you want is not always solution 1. So you will still need the click to validate the solution to apply.
