Shorten polylines a given distance

Question

I have a polyline dataset with lines of different lengths. I want to shorten all polylines the same distance on both ends (e.g. 10m each side). Is there a tool or script available that could help me do this? I want to automate this process, so manual editing is no option.

I´m using ArcGIS 10.0 with an ArcView license.

you can use this simple steps as arcpy script, or as Model:

use the tool Feature vertices to points with BOTH_ENDS option.
Buffer the resulted points with 10m.
Erase the lines using the buffer result.

in the case of Arcview i have found this erase script , or this question about using erase in arcview

Good idea. Unfortunately I only have a ArcView license. Both, "Feature vertices to points" as well as "Erase" require ArcInfo. I´m able to do the "Feature vertices to points" using a free ArcGIS extension, but I don´t know how to do the "Erase" without adequate license. – Martin Mar 26 '13 at 10:49

Thanks, the first script is outdated I think, but the second link was helpful – Martin Mar 26 '13 at 16:03
