I am trying to add some user data objects (which are derived from UserData) to
surfaces and to trims. But by saving the file the ShouldWrite is not executed
for the user data objects which are laying on the trims, but it works properly
for the surfaces.
Also if I try to edit some points of my surface the user data
method onDuplicate is not performed and all the user data is lost. That happens for both, the trims
and the surfaces. Is there a way to manually enforce the run of those
methods or to overcome this problem?
I am using Rhino Common with C#.
