I have a strange happening. We've had surveyors prepare a site plan for a commercial site and have imported his DWG drawing into Archicad, converting it into a PLN. Scales are sorted and it looks good. We now want to import the contours from the PLN drawing into another site plan for the same project and can't do so. We can copy it from the original PLN drawing. However when we PASTE it into the other site plan all is well - we can see and adjust the contours to their correct position - until we cancel the marquee around the pasted image. Then, the imported contours disappear. Opening all layers doesn't find it and I don't know where it has gone. Is this an Autocad or an Archicad bug? Or have I missed something?
Useful suggestions are appreciated!
