This query has come up twice recently. “Is there any way you can stop a stair from masking out in a room colour fill, so that the stair itself is the same colour as the room fill?” In essence, what is not required is this……
Instead this is actually what is required…..
There is no automatic way to do this unless you setup some smart filters, but if you assign a colour override to the stair the same as the colour fill of the room, it works fine, not ideal, but it solves the problem quickly & promptly.
Remember the stair is not included within the room calculation & you can’t do much about the railing!
