Is it possible to get the room boundary line in a curtain wall to be set to the inner face of the mullion instead of the inner face of the glass?
I have looked at the System family library but cant find a setting for changing this.
Also, setting the location line is greyed out. Why?
If I draw clockwise I get the location line on the inner face of the glass even if the greyed out location line setting in the options bar is set to center.
From my observations the room boundary is on the central axis of curtain wall that by default is the central axis of the mullion.
Make a new type of curtain wall and a new type of mullion with an ofset..
If you make a mullion with an ofset of half of its thicknes you can change the position of the axis to be left side or right side as in my images. The Room boundary will be on this axis position..
You have to adjust also the position of the glass pane:
the room boundary , now, automaticaly goes on the interior side of the mullions:
Thanks for the responce.
I have one additional question to this please.
What if the Curtain Wall is curved?
if you use the same mullion type as in the previous example it will work for "curved curtain walls" too.
It is true that the Room is calculated by an arc tangent to the interior face of the mullion but if you have a large arc or many grids the arc and the chord are very closed one to another....
So, if you have a large grid. Is the only way to make the arc not overlapping the inner face of the grid frame, to use room separation lines?
We have not to forget that in true a curved curtain wall is a successions of chord that approximates an arc.
If we have few segments we can work with a chain of straight curtain walls and changing the mullions to corner or trapezoid corner mullion ( also with an offset of half thicknes if we want the room border line to be inside)... The Room limit will follow the interior side of the chained curtain wall.
If we want a real curved glass wall we can made a Basic Wall with material:glass....
