I export Map 2008 mpolys with object data to shp files. ArcGIS sees some objects in the shp files as negative areas. Tracing back, I found that Map is generating random negative-area mpolys from closed polylines. Doesn't matter whether or not the original polyline is digitized in clockwise or counterclockwise direction, contains doughnut holes or not, or has object data attached or not. Also, at random I’ve selected negative mpolys, gone back to its original file and its original unaltered polyline, regenerated mpoly and now it’s not negative. Question 1, why negative areas?
I can get rid of the mpoly negative area using “MapMPedit” Rebalance, but it’s a pain when several hundred mpolys have negative areas. However, after I rebalanced all the negative mpolys and exported a shp file, ArcGIS now sees ALL the objects as negative area. Question 2, anybody seen this, and any workaround?
