Plan:
1. set 'Door Setting', check 'use part line style' - on object info or 'setting' button, set your lineweight now-door leaf, swing and wall line for your RCP.
2. put door symbol on the class you want, make sure you uncheck 'use at creation' because it will override your line weight setting from 'use part line style'
3. Have 'sill' class on, 'ceiling main' class off.
For RCP,
1.Turn off 'sill' class
2. Turn on 'ceiling main', your wall line should already been set.
you can turn off 'wall componet' in viewport.
