We've got about 300 GB of Autodesk Recap RCS files of about 4km of Amsterdam citycenter environment. We're looking to extract only the building facades from those files. We have got boundarys of 1m offset of those facades.
Unfortunally, Recap can't clip within a boundary. That's why i want to bring everything to Lastools or cloudcompare to throw away 95% of all the rubbish and keep only the points within the boundary.
But Recap is extremely slow in exporting to *.E57 files. That would cost me about a week to export file by file.
I've looked into FME, but that can't read RCS files.
I've looked into DECAP.exe (the command-line tool for Recap to batch automate processes) but i can only find import commands, no export function

The only other program i could find that can read RCS files is Pointfuse, that is not available to me, and can't clip within a boundary (for as far as i could tell).
Who knows what other software can read *.RCS files or knows another way to convert about 600 RCS files of 500MB each.
Thanks in advance.
