I have a civil drawing (site plan with contours both existing and proposed) and Autocad will not allow me to select any of the object with a non-zero elevation (z-value).
If I draw a line or polyline with a zero elevation, I can select it as usual for move, copy, list, etc. But if I change the elevation, I can still see it, but can't select it.
Any else ever had this problem? Anyone ever had it and been able to fix it?
I have opened the file in BricsCad and can select all objects as selected, but when I save the drawing and re-open it in Autocad, I get the same, no-select, problems.
Thanks,
David
