I have opened the map data located at https://www.arcgis.com/home/item.html?id=f38b87cc295541fb88513d1ed7cec9fd and tried to filter out only the highway level data by right clicking on North America Detailed Streets and then going to Open Attribute Table. At the table I am Selecting Attributes "PRETYPE" = 'HWY' and then trying to export the data. I am assuming that this will filter on only the highway data and will make the data set much more manageable. I then export the data to file and I am having difficulty loading it back in. Is this the correct method for filtering out the data? Otherwise it is simply a massive amount of road data that I am not interested in and really kills my system. If I am correct in my way of exporting what is the correct way of importing and should I then be able to perform the Feature Vertices to Points functionality on the data?
