As I understood things, the ability to import and export Parametric Constraints was part of Open Roads. If this is true, where is its interface within the tools? And if it is not, when will it be made available. This was a valuable capability. Actually, a similar capability for all of the corridor controls would be extremely valuable.
Please refer to the wiki below for the answer to your question.
