Phil,
I have posted 2 files: Before.cal and After.cal example files of the
distortion in Autodesk.autocad.customer-files. All the LD2005 stations in
office produce the same error while rubbersheeting. We used triangular
rubbersheeting in this example but polynomial method yields the same error.
Before.cal - raster before rubbersheeting
After.cal - raster after rubbersheeting,
4 anchor points at 4 border corners
2 anchor points at North and South end of line labeled 97.37'
1 source - destination point at the East end of line labeled 125.18'
1 source - destination point at the East end of line labeled 124.17'
Requested shift at the 2 source - destination points was no bigger than 1%
of the length of entire raster image in this example.
We tested much smaller shifts with exactly same very bad, unacceptable
result.
We had to switch entire office back to LD3 where rubbersheeting works.
Any help will be greatly appreciated,
