I'm trying to change flat beams to sloping. I've created the necessary reference planes, but when I try to specify by name, they don't appear on the list.
If I place a new beam, I can pick the planes and they are added correctly.
I've tried adjusting the view range, making sure all planes are switched on and doing it in Plans/Sections/Elevations, but nothing is working.
I know this is going to be something daft, does anybody have any ideas?
Cheers,
John
