Using Map 3D 2010, I have edited a shape file of water lines originally create using ESRI ArcInfo. I connected to it using "Data>Connect to Data" under Display Manager tab, then added features and added some attribute data in the table, then checked the features in.

Two problems:

1. ArcView 3.3 and 9.3 won't read the shapefile correctly - the new features don't show up graphically. I can see them in the table though. Perhaps ESRI products aren't suppose to be able to read AutoCAD shape files?

2. I have a "LENGTH" field that I want to populate with the actual length of each feature. Is this possible?
