Cheers for the help. I've now got rid of the dotted line.
West View issue somehow resolved itself, I had moved the elevation markers ( and the dotted line ) but that didn't seem to do anything the, today, when I went to the West elevation my building was there. Strange.
Stairs - I still have an issue in as much as when the direction arrow is selected I don't get an option for multiple/continuous. Could that be down to the street level having a taller ceiling than the other floors - I created each level separately. Also, on another floor the up/down direction arrow has completely disappeared, don't think I've deleted it, but maybe I did. I'll perhaps redraw it and see if this helps.
Please can I check something else as well with you?
On the Underlay for Level 1, I have it as Base Level set to Level 1 and Top Level set to Level 2 with Underlay Orientation set to Look Down.
On View Range from the Extents section, The Top Associated Level ( Level 1 ) is offset 2300mm, Cut Plane is greyed out but its Offset is 1200. Bottom is set to Street Level with no offset ( for my building the levels are street, level 1, level 2, level 3 and roof ). View Depth is set to Street Level with no offset.
I have just checked Level 2's View Ranges and the offsets are all 1200mm. Level 3 has the same offsets as Level 1 but both Top and Bottom Primary Ranges are set to Level 3. Street Level has been set with Primary Top and Bottom set to Street Level.
I'm not sure where these offsets or Primary Range settings came from but I was wondering what they should be set to really? Hope you can help.
