I find it useful to use ARCGIS at very large scales. I use it to map features at the micrometer scale. So - at measuring unit of 1 centimeter this might be a scale of , 1:0.001
However at these scales its not possible to generate smooth curves - as vertices are deleted upon finishing the sketch. Seems that the vertices are "legal" but that they cannot be processed due to proximity! There appears to be a limit to how close vertices can be to each other at these scales. See example. The width of the image is 0.3mm or 300 microns and the line was a smooth curve of vertices - until it was finished - end result missing vertices.
I have tried setting up a map without coordinates and will custom coordinates with an origin of 0,0 etc. But get the same result at very large scales. Any thoughts appreciated.
