I'm trying to separate historic network data (by symbology) that I need in the same shapefile, as my data contains two different types of network "Route" and "Stairs".

I tried using the classic that is adding a field to the attribute table which actually separates the polylines by their type accordingly. But the problem resides in the fact that the data I'm about to vectorize is unbelievably big.

So what I'm really in need of here is a way to group edit the many polylines and separate them in a field with either "Route" or "Stairs", in hopes there is a way around changing the type of network one by one which would take some undesirable amount of time.

    What is your question? If there was a single question mark somewhere in your question body that would be obvious. – PolyGeo Jun 23 '20 at 20:46
  • @PolyGeo Did you actually read the post? I clearly mentioned what I needed, which is a way to group edit the Type field into the according one of two network types "?" – Mohammed Imad Eddine Alliouche Jun 23 '20 at 21:18

    I never comment on a question that I have not read. Your question body appears to contain at least two statements that could be interpreted as questions but neither is marked as one to tell us the single question that you wish to ask. Network Analyst questions are amongst the most time consuming that I volunteer time to help with here and I do not commence them until I am certain about what is being asked. – PolyGeo Jun 23 '20 at 21:36

    I'm sorry that I'm not able to volunteer more time to get this into the shape needed before I would be willing to develop an answer. Hopefully, another potential answerer will be willing to work with you on this. – PolyGeo Jun 23 '20 at 22:42

    What exactly is your question? How to group edit features? Select all the route features and set to "Route" then all the stair features and set to "Stairs". Is that what you're trying to do? – Midavalo Jun 24 '20 at 0:12

You can edit attributes of multiple selected fields from the attribute table by using the Field Calculator.

  1. Select all the features you would like to edit (eg all the Route features)
  2. Right-click on the column header (Named Type in your screenshot) and click on "Calculate Field"
  3. In the Field Calculator window enter the value you would like to populate onto the selected features, eg ROUTE
  4. Click OK to calculate the value onto your selected features.
  5. Clear the selection and now select all your Stair features and repeat the process.
