HI ALL,
I can't seem to view parts of drawing when in model space. it suddenly vanished, so i tried to copy and paste these parts from previous version of drawing. But it would not paste and not even paste from within the same drawing. Tried all copy with base point etc. So i redrew these parts and when i went to print in paperspace the bits were there, with the new lines on top.
Have checked all layers are not off etc, but to no avail.
 
Any help would be appreciated.
 
Thanks.
