Is there any way to create the new prBoundary and snap boundary object in SKILL in IC 6.1+? From the documentation, all I found is leHiCreateSnapBoundary() and leHiCreatePRBoundary(), both are interactive function that pops up a form, not the procedural SKILL function I need. fyi, I would like to transform an existing prBoundary layer into a prBoundary object silently.
