I'm totally lost here. The 2 people who were in charge of this project left last year and now it's time to update this data. We have a Geodatabase with multiple features. One being SLEEVES, we have 4 updates to these from our client. They sent them in an email in Excel format. So I have the coordinates of each point and other descriptive data. That's all I have to work with. Basically I need to add these 4 lines to the database with all the other sleeves so they show up in the affected MXD maps as well. If anybody could walk me through this I'd really appreciate it. Not sure where to begin. ArcCatalog or ArcMap or both? Thank you
