The same polyline end point connection

[LIEPAJABUILDINGBOARD]

Hi!

Is it possible to automatically connect polyline feature end points?

I have a polyline feature class of building contours but some contours are not locked.

Is there an option to lock all of building contours automatically for all contours (to connect end points of each polyline)?

You may want to try the Snap (Editing) geoprocessing tool on a copy of your data to see if it accomplishes what you want to do.  Or you can build a geodatabase topology with the rule "must not dangle".  After validation, you will find all the lines that fall outside of the cluster tolerance.  The ones that fall in the cluster tolerance will snap to the nearest vertex or line.
