I am a bit of a novice so this may be simple. I have ACad2000 and often cut & paste from one drawing to another - this works by highlighting the view to transfer, select copy, then I can usually paste it or paste as a block on anotyher open drawing / file ( i.e. not just anohter view of the same drawing but say copy a machine elevation and then import / paste it into an overall facory layout.
I have done this successfully with a number of drawing elevartions from different suppliers but one supplier's drawings in particular causes me a problem. No matter what I try they will not copy. I have spoken to the drawing draftman and asked if there is a lock or other papameter to switch off to allow their drawing to be copy & pasted elsewhere - they do not know of such a restriction.
Any ideas ???
