Adding an adjacent fabric feature causes the existing adjacent feature to be duplicated,

I couldn’t figure out why adding an adjacent fabric feature causes the existing feature to be duplicated,

For example, in the screenshots below, it is needed to add a parcel adjacent to parcel#13. As the new parcel is digitized and saved, it is observed that parcel#13 is duplicated.

What might be the issue here?

Thank you

When you enter a parcel in the parcel fabric, you must enter the WHOLE COMPLETE traverse loop. Even if the parcel shares a boundary, you still must enter the whole parcel traverse, close it and then join it.

Thanks Christine,

This will add much of work that we need to digitize the shared boundary! And how to make sure that they will be identical? What if one point is missed and thus gap\overlap\new polygons are created?

The idea is that you are entering a parcel from the legal recorded document (that has boundary dimensions on it) - not digitizing. If you are digitizing, then the parcel fabric might not be the best or most efficient tool for you.

The idea of the parcel fabric is accountability, and accuracy. The parcel fabric is used to get your data accurate to the legal record and spatially accurate to survey control

The parcel misclose lets you know if there is a blunder in your data entry.

Practically, there is no why to have the new data surveyed from the field (by total station or GPS device with 2cm accuracy) to be 100% identical to the data already stored in the fabric. At the end, the shared boundaries between the data stored in the fabric layer and the new added one needs to be manually modified (reshaped) so that the common boundary gets identical.

You are correct. Thats why we have the joining process. If you look through the doc here you will see that lines can bend and flex to misaligned boundaries... YOu can use two join options - move the new data to the existing boundaries OR move/bend the existing boundaries to the new data being joined.

If you run a least squares adjustment, you can use accuracy levels to weight down the good data so that the less accurate data adjusts around it and the good data maintains its shape.
