Cable tray has a parameter for bottom elevation which is used in all our tray tags.
When the tray slopes up or down I want to be able to tag it with the 'start' bottom offset and 'end' bottom offset.
Like this:
200x30 LV Basket sets from 3000 to 3300
Currently it will only use the start and end offset which is in the middle of the tray which is completely useless.
