Hi Michal - I do not see a good way to do this with any guarantee that the shape will not change too much if the points are to be moved but it seems reasonable to figure out a way to remove points to eliminate short segments - would that be OK?
@michal.sowa - see if this python helps at all -
CullShortSegments.py (1.2 KB)
To use the Python script use RunPythonScript, or a macro:
_-RunPythonScript "Full path to py file inside double-quotes"
-Pascal
