Using the Erase Short Objects cleanup action, you can locate any objects shorter than the specified tolerance and erase them. This removes short isolated linear objects and short linear objects that are part of a polyline.
This action erases any objects or separate segments shorter than the specified tolerance.
This action is like the Dissolve Pseudo-Nodes action, except Erase Short Objects removes both the linear object and associated nodes.
Depending on your data, use Snap Clustered Nodes next, to correct errors that might result from the Erase Short Objects option.
