After data loading is complete, it is recommended that you perform the actions described in the following sections to check the parcel fabric for errors and ensure good editing performance.
Re-create spatial indexes
ArcGIS uses spatial indexes to improve spatial query performance on feature classes and datasets. Identifying features, selecting features, and panning and zooming all require ArcMap to use the spatial index to locate features. Re-creating a spatial index is recommended when a large number of features of different sizes is added to an existing feature class.
If you loaded very large parcels together with small parcels into the parcel fabric, it is recommended that you re-create the spatial indexes of the parcel fabric Parcels and Lines feature classes. This ensures good pan, zoom. and selection performance in a parcel fabric after data loading.
Check the parcel fabric for topological errors
Run the Check Parcel Fabric command to check the parcel fabric for topological errors. The command identifies and reports data corruptions such as out-of-sequence parcel traverse lines, parcels with dangling boundary lines, and invalid dimensions. To run the command, right-click a parcel fabric dataset in the Catalog window and click Check Parcel Fabric.
Reported errors do not need to be fixed immediately. Errors can be fixed over time, as needed in the area in which you are working. If you are adjusting a selection of parcels using the parcel fabric adjustment, it is recommended to have all check fabric errors fixed in those selected parcels to ensure a successful adjustment.
Merge lines and create line points
Line points are not created during the data loading process. Use the Merge Courses tool 
to merge collinear parcel lines into a single line and create line points. This tool can be used to merge those lines that should form a single parcel line but have been split by adjacent parcel points. Once the lines are merged, adjacent parcel points lying on the line become line points. To use the tool, select the parcels for which you want to create line points, right-click, and click Merge Courses.
Merge points
The parcel fabric should have one common point for all coincident parcel corners, curve center points, and endpoints of connection lines. Common points maintain the internal topological connectivity of the parcel fabric and minimize the occurrence of slivers and gaps. Use the Mean Points tool 
on the Parcel Editor toolbar to merge unconnected clusters of points into a single point.
Check parcel miscloses
The difference between the starting and closing points of a parcel is referred to as the parcel misclose. The parcel misclose is a measure of the accuracy of the parcel dimensions. The smaller the misclose, the more accurate the parcel dimensions. Larger miscloses indicate errors in the original survey measurements or data entry.
A misclose ratio and a misclose distance are stored for each parcel in the MiscloseRatio and MiscloseDistance fields, respectively, on the parcel fabric Parcels table. The misclose distance is the difference between the starting and ending coordinates of the parcel traverse. The misclose ratio is calculated by dividing the misclose distance by the total distance of all lines on the parcel and expressing this value in reciprocal form. For a closed parcel, this means the misclose distance is divided by the record values on the lines that define its perimeter. Parcels with misclose ratios between 1:1 and 1:1500 should be reviewed for errors. These parcels could be corrupt or invalid and may need to be unjoined and re-entered. Misclose ratios between 1:1500 and 1:100000 are acceptable.
Identify those parcels with bad miscloses by sorting the Parcels attribute table by the values in the MiscloseRatio field.
