I don't actually use the Graphisoft doors and windows, so I will have to do some experimenting.
It looks like they use a solid line on the inside and a dashed line on the outside.
I am unsure at the moment if the side the dashed lines are on is linked to the reveal side or the door/window orientation.
If it is linked to the reveal side you should always have consistency if you schedule the view from the reveal side (and transparency is turned off).
If it is linked to the orientation then you will have trouble if you schedule from the view from the reveal side
So of course when ever you have transparency turned on you will see a solid line - you are in fact seeing both lines.
Is there any control in the objects (or MVO settings) as to the line types used?
I will see if I can have a look a little later.
