question about "hatches"
hello,
i have read in the documentation, that all references are automatically corrected, when deleting an entity. for example, if we have a line entity, which is referenced by hatch and we delete it, hatch will no longer reference that entity. when i tested this, hatch referenced null object.
this is ok.
but i have a question.
if i want to split an entity (for example spline or polyline into many line segments), how can i achieve, that all objects which reference original entity are updated with object id's of new created entities?
is this possible?
regards, tomaz
if a hatch is associated with polyline you want to explode polyline entity contains hatch's object id among it's reactors.
you can use oddbhatch::getassocobjidsat() and oddbhatch::setassocobjidsat() to replace polyline id with ids of lines obtained from polyline exploding.
