10.10 Cross Sections Filters

When you view an individual cross sections you can see if it has errors because the cross sections has points that should be marked as filtered. Instead of going to the points cloud containing the cross sections, eliminating the points and recalculating the cross sections, you may access the selection filters, using the corresponding toolbar. The difference is that the cross section will be recalculated automatically by eliminating and including points.

Here you can see a faulty cross section because there were points which should have been filtered. The points correspond to the roof of a van that was close to the scanner.
