A new release from Pythagoras:
Some of the new features:
Automated point cloud vectorization
Classification of point cloud
Enhanced DTM performance
Updated profiling tools
General performance upgrade

There are now several software packages with the ability to vectorize of point clouds, but I've yet to see a comprehensive review of these products, comparing tools, features, price, and performance.

The classify ground looks like it did a good job, but this is possible in lots of software.

The vectorise edges from an image of road markings had a lot of extra lines created that would need clean up. Creating those manually would be quicker overall I reckon.
As for the vectorising of the building facade from point cloud data, there was even more extra lines created where no detail exists.

Unfortunately, it still looks like the cleanup time is too much in this sort of product that a well skilled CAD monkey can't beat and probably with tidier CAD practice. (not lots of unneeded nodes in the linework etc).
