I recently imported a few survey points from a DXF file that was based on the survey data as follows:

1 10000.000000 10000.000000 1000.000000 cp
2 10000.000000 9816.600000 994.740000 cp
3 10000.000000 9816.600561 994.735805 check
4 9997.599585 10001.415944 1000.008057 check
5 10004.190473 9994.843726 1002.256642 check
6 9975.669804 9860.892925 996.019052 bm1
7 9975.699483 9860.887761 996.018367 toc
8 9975.825216 9860.273152 995.556634 boc
9 9983.478256 9866.112028 995.706783 toc
10 9984.042275 9865.958938 995.300499 boc

the survey data units are feet, as usual. However, when I look at the properties of each point, it says the coordinates are 12 times the imported value. This makes me think C3D changes the units during the import, but I don't see how to undo this change. Any ideas?
