Hi,
I would love to be able to place a plant and it automatically assigns to a class, regardless of the current class setting.
Can't offer help on this issue, but would like to be able to have plants assigned to a particular class as you said.
Also, apart from the overall class of plant object, we have long struggled the problem of the sub-classes of the components of a plant (they have default classes for trunk, canopy, etc).
We'd love all the classes and sub-classes to be ones that are part of our company system and not Vectorworks Defaults.
