I am using autocad 2004 and I'm drawing a floor plan. I xref in the 2d points including levels and string lines etc (created using a theodolite on site by a surveyor) and bring them in on layer 0 and lock the layer, but when trimming or extending I am able to select the seperate lines on the xref which I do not want to do so I then locked all the layers in the xref but I can still select them when trimming and extending as the cutting line. The last version of Autocad I used was r14 and have only just recently changed, is there a way in 2004 to stop the selection of xref lines or is it something I am going to have to get used to? I think once a layer is locked you shouldn't be able to do ANYTHING with that layer, it makes no sense to me.
anyway, any usefull replies will be appreciated
