Around a two years ago, I made the permanent transition from ArcMap to ArcGIS Pro. All of the data is stored in the same SDE. I noticed that after the transition, when I brought the parcel polygon layer into the map, it came pre-symbolized the same way I had it set up in ArcMap. Hollow fill with bright yellow outline. This happens regardless of the pro project that I bring it in to. I can open a new project and bring parcels in and they are symbolized with a hollow fill and bright yellow outline. It comes in the same everywhere, whereas it used to come in filled with a random color and a solid black outline. You could bring in three copies of it and each copy would by a different color. Now, if I bring in three copies of it, all three will be symbolized the same way. In fact it even pulls in a labeling expression. I actually love this and want to figure out how to replicate it (without having to deal with layer files) because it would be a good way to create and maintain a good cartographic standard. Any ideas on how to change this?
I think what you are referring to is the feature template in the database?
