Thanks to all who answered my previous post... Need some help, again...I'm a Micro user working in a field office with AutoCAD 2002 & 2004...with no manuals available...with cad guys seems to be working on their own thing...not thing is consistent... 1. How can I 'COPY' individual lines, arcs...etc from reference files that is attached into your active file you're in with out bring in the whole file? 2. How can I 'LOCK' the elevation (z axis) to a specific Z value as I was to place everything in a 2D plane? Thanks in advance and appreciate the response....
