We had added some of our own symbols into our symbol library and modified
the dwg for those symbols to be equivalent to the Carlson symbols already in
the library. We enter initial survey points, do some editing of the drawing
and then go back to enter more points and then new points come in at a
miniscule size (about 1/100th of normal) but carslon symbols still come in
correctly. When using the symbols in a new project, they come out at the
size we want and equivalent to the Carlson symbols. Any idea where some
other scaling factors are that might affect symbol size in this way?
