I am using ArcGIS Pro with a Basic license. I apparently need the standard license to get the feature class to polygon tool. I can't buy that right now, and another company sent me CAD linework that needs to be polygons. Do I need to go through and create a polygon for each line manually since I don't have the license or is there any workaround to make all of these lines into polygons?
Not sure if this helps: https://support.esri.com/en/technical-article/000007258
If you have the drawings themselves, you could georeference them and use it as the basemap with which to create your ploygons.
I have been fortunate to have ELA licenses my career that include Advanced, but I am a big fan of XTools Pro, an add-on for ArcMap and Pro. There are free and trial versions and they both include a lot of Standard and Advanced functionality.
